Stupid Evil

""Crush! Kill! Destroy! Crush! Kill! Destroy! Crush! Kill! Destroy!!!!""

The logical extreme of the Obviously Evil motif. These are the people who seem to think having an evil alignment means doing nothing but evil every waking moment, even out in broad daylight. Like, say, stabbing a peasant while several high-level town guards are watching for no reason other than you were bored. If the other party members are lucky, this sociopathic insane behavior will extend solely to the NPCs. If the other party members are lucky, that is. The Stupid Evil character is frequently the type who will betray and murder his teammates on the flimsiest of pretenses (even if he'd gain no advantage in doing so), simply because it's EEEEEEVIL.

Oh, and they get angry when they have to suffer consequences for their actions, like guards and bounty hunters after them. It's all about them, after all. If a Stupid Evil person has a choice between accepting a reward for accidentally finding a dog or killing the reward giver, they will choose killing every time. (Somehow figuring out how to do both requires systematic patience and intelligence that isn't part of being Stupid.)

Similarly, the D&D sourcebook Book of Vile Darkness spent a good while detailing how to run an evil character without being a mass-murdering lunatic; but it does give tips for that, too, since even cartoon supervillainy has its place.

Sadly, if a computer-based RPG offers an "evil" path, it's usually Stupid Evil, and it involves committing completely random acts of violence just to get those precious Karma Meter points required to unlock the top tier evil abilities. Only relatively recently did they start adding options for players who want to play sneaky evil characters, with opportunities to manipulate other characters into doing your bidding, or even cooking an Evil Plan. Sometimes, however, this is played anyway because of the Rule of Fun. Watching the ensuing chaos from randomly attacking people is sometimes fun, even if the novelty soon wears off.

This is different from Complete Monster, usually; those monsters almost always have some kind of goal, desires or something else that they're willing to commit atrocities for; Stupid Evil means doing it when it is both pointless and stupid, although the former sometimes does actions that are considered this and earn a fitting Karmic Death.

It is notable that this is, along with Chaotic Stupid, is often given as an official reason in a work for why the forces of evil haven't completely destroyed the forces of good yet: They're too busy behaving like this, usually towards other evils, to focus on uniting against good and conquering the world. There's often a conscious concern on the part of the good guys of this fact.

Compare Lawful Stupid, Chaotic Stupid, Stupid Neutral and Stupid Good. Contrast as well Pragmatic Villainy; a villain who is evil only when it benefits them more. Chaotic Evil is the alignment most likely to be reduced to Stupid Evil, for some reason. Threw My Bike on the Roof often overlaps with this.

Anime and Manga

 * Hansel and Gretel, the insane twins from Black Lagoon. After being hired to perform an assassination, they proceed to abduct and torture a bunch of random mooks for sport, and then murder the person who hired them, not because he was planning on betraying them, but because they just felt like it. They then decide to go through with the assassination anyway, even after it's pointed out to them that they are no longer being paid. It should also be noted that their target makes a policy of surrounding herself with some of the most deadly soldiers in the world, is a world-class markswoman in her own right, and is justifiably considered within the series to be the most dangerous woman alive... and the twins try to take her out armed only with an axe. It turns out exactly how you'd expect.
 * Another example is Chaka from Fujiyama Gangsta Paradise, who got the bright idea of kidnapping the daughter of his boss, a Yakuza. This incurred the wrath of not only Ginji Matsuzaki, her hulking samurai-sword wielding bodyguard, but Revy as well. Needless to say, his fate was not pleasant.
 * The Apostle Wyald in Berserk, a berserker who put so much effort into being a vicious sadist that he tried to kill Griffith, the one person he was absolutely not supposed to kill. When he's called on it, he mouths off to his superior, Zodd, who tears Wyald in half for being such a moron.
 * Pretty much the entire cast of villains in Ranma ½ have moments of acting like this, particularly in the manga version and particularly if "Smart Evil" threatens the status quo. Two of the most notable examples are Soun Tendo stealing a cure for Ranma's curse with the intent of blackmailing him into marrying Akane with it, only to blab about it in front of Genma Saotome, who promptly stole it himself... and Nabiki's attempt to sell Ranma Saotome's engagement to one of the other members of his Harem during her stint as his official fiancee, only for the girls to spontaneously decide that it would be better to simply kill her rather then pay her price. If it wasn't for the fact Ranma is a Jerk with a Heart of Gold, she would have died.
 * Ribbons in Mobile Suit Gundam 00 blows up his own allies, and replaces them with worthless kamikaze machines that are a complete waste of technology and time; the only goal they achieve is making him look even more evil for using such machines. Most of the atrocities his puppets committed early in the second season including blowing up a country or two were committed for no solid reason. The only reason he gets away with it as long as he does is due to Kataron's ineffectiveness; without the Meisters, Ribbons can do what he well damn pleases, as resistance will be effectively taken out in about a couple of years.
 * Lolly and Menoly of Bleach. "Let's beat up the human girl our boss told us to specifically not hurt, as she is useful to "the plan", for no reason other than we're jealous! Then, let's act surprised when our immediate superior mauls us up for it. Ooh, ooh, and then we can hate her even more despite the fact she took pity on us and saved our lives!!! And we can try it again, only this time let's have our other immediate superior kill us!!"
 * Their ungratefulness, while no less stupid, is at least explained by Fridge Brilliance: the two Arrancar were terrified of Orihime after she used God-like abilities to bring them back, since they are creatures of death.
 * Arguably, Aizen himself falls into Stupid Evil territory when he, with his justification of getting rid of those he considers weak seeming completely ridiculous; that person was still one of the strongest on his side and, more importantly, this was in the middle of a battle where his own forces were severely weakened already. He should have at least just waited until the battle was over.
 * Aaroniero Arruruerie was obviously far superior to Rukia, and could essentially have killed her immediately. Instead, he feels the need to pointlessly mentally assault her. The only possible reason is that he's just really sadistic. But what's the point?
 * Zommari is in a similar boat: his body control powers are so broken he could have killed Byakuya with little effort, but he proved so full of himself and explained everything about his powers in such painstaking detail that he ended up dead.
 * The buffoonish Complete Monster Genma of Darker than Black has a scene where he uses his Instant Armor powers to dismantle a truck and then amuses himself by beating up the protagonist while transformed into a human mech. This wasn't the brightest idea for two reasons: First, the protagonist was interested in the MacGuffin in one of the trucks, and Genma showed him which was the decoy. Second, when the protagonist starts escaping, Genma's first reaction is to get in the truck to pursue him, but then he remembers he just disassembled his mode of transportation.
 * Paul from the Pokémon anime trained his Chimchar vigorously enough that it was legitimately exhausted enough not to be able to battle the next day. We know this because Nurse Joy, a medical professional told him this. So what does he do? He forces Chimchar to battle anyway, and then when she turned out to be right, he was, for some reason, disappointed by this and left Chimchar, thinking it was simply too weak. This led to Ash taking Chimchar into his care and raising it into one of the strongest members of his team.
 * In Fullmetal Alchemist, both Lust and Envy fall into this, loving to inflict pain so much that they can't resist "twisting the knife" and antagonizing the heroes, even when it is foolish to do so. In some ways, Lust is the worst of the two, as while Envy is a deranged psychopath, he at least generally avoided trying to kill humans who were "sacrifice candidates", whereas Lust was inexplicably unconcerned about this.
 * In Yu-Gi-Oh! doing at least one dumb thing that leads to your defeat is practically a prerequisite to being a villain sometimes. Examples that stand out:
 * Yami Marik does this quite a lot, most notably when he sabotages Noah's computer system during the Virtual Nightmare Arc, not seeming to realize that destroying it would kill both Yugi and Kaiba, ruining the most vital part of his master plan: gaining their two Egyptian God Cards. To make things worse, he laughs like a lunatic while doing it.
 * This regular Marik does something very stupid too (which was the biggest reason his Super-Powered Evil Side was able to subdue him and take over in the first place). First, he puts a counterfeit copy of The Winged Dragon of Ra in Rishid/Odion's deck, and given the fact that every other minion who tested these phonies died horribly (as Ra does not like being insulted), it really wasn't smart to have such an important minion have one. Rishid, on the other hand, is smart, and knows that it would likely be dangerous to use it; he would have beaten Jonouchi/Joey without it, but when it seems likely that everyone will figure out that Rishid is acting as Marik's stand-in, Marik orders him to use it in order to cover up Marik's true identity. Rishid reluctantly complies, and... it turns out Marik really should have listened, because the real Ra ended up destroying the fake copy while smiting both duelists, and Jounouchi managed to win by technically...
 * Yami Bakura shows this in his duel against Yugi in the final arc of the series. He uses a card which forces Yugi to discard the same number of cards from his deck as the number of monsters that are on the field, and combines this with another card that eliminates his own graveyard, making him immune to the effect and allowing his monsters to remain on the field as phantoms (without the ability to attack or defend, but still counting as monsters), the intent being to cause Yugi to lose the duel by "decking out". It eventually gets to the point where Bakura could win the duel simply by ending his turn without making a single move, something he even points out, but he decides instead that watching Yugi squirm would be more fun and continues the duel, using a monster whose effect further depletes Yugi's deck by five cards. Yugi is left with only one card left in his deck, but it just so happens to be the exact card needed to defeat Yami Bakura's strategy, which costs him the duel.
 * Moving to the Sequel Series Amon showed this in Yu-Gi-Oh! GX. His ace card was Exodius the Forbidden Lord. It seemed completely indestructible and immune to all card effects, and granted him an automatic win if it attacked five times. But he became so Drunk with Power because of it, he challenged Yubel using it... Completely forgetting that Yubel was the one who gave it to him. You'd think if anyone had known weakness in this card, she would, and she did. It ended badly for Amon.
 * Yu-Gi-Oh! 5D's: Divine, Aki's Evil Mentor and a complete asshole. After having been tricked into revealing he was responsible for the death of Misty's little brother, he mocks him and her anguish over his death... Doing so while Misty has her Earthbound Immortal (a lizard-demon the size of a skyscraper) summoned and in plain view. Cue Divine getting Eaten Alive as payback.
 * Aporia, much like Amon, tries to turn against Z-One with incredibly powerful cards that Z-One himself gave him. Aporia doesn't even manage to scratch Z-One, and is defeated in the most humiliating way possible.
 * Yu-Gi-Oh! Zexal:
 * Tron has a habit of giving his henchmen cards that are too powerful for them to control, which cause disasters when played. The first example was when he gave IV a Spell Card called Flaming Hell Blessing to use in a duel against Rio Kamishiro; it won the duel for him, but it also caused a raging fire that destroyed the building they were in. Rio was in the hospital for months recovering; IV managed to get out, but not unscathed. The accident  left a scar on his face that never healed.
 * Even worse was the card he gave III to use against Yuma, Angolmois. The true effect of this card was to open a portal to the Barian World, which would basically have done the same thing that a black hole does. If it had worked, it would have killed everyone, Tron included (and he didn't even seem to care; he was laughing his head off as he watched the duel).
 * In Yu-Gi-Oh! ARC-V, after Sora true nature is revealed in his duel against Kurosaki/Shay, Sora gleefully mocks his opponent about how much he enjoyed decimating Shay's home dimension and reducing it to a war-torn wasteland. He seems to completely forget that they're in the middle of a duel and Shay has just summoned his second-most powerful monster, the Duel Monster's equivalent of a B-52 Bomber, and when he brings out his most powerful monster, well, suffice to say, Sora gets thrashed within an inch of his life.
 * And of course, the movies:
 * Anubis from Yu-Gi-Oh! The Movie: Pyramid of Light. How else would you describe someone whose plan involved manipulating Kaiba to get to Yugi, which, in effect, opposes both of them simultaneously?
 * Paradox from Yu-Gi-Oh!: Bonds Beyond Time was worse. A bad guy challenging the main protagonist of a series is one thing, this idiot decides to challenge the protagonists of three series of a franchise simultaneously.

Comic Books
"Psimon: So who do we blow up first? Mammoth: I want to destroy the United States for putting us in jail all those times! Psimon: Shimmer, please explain to your brother that it's a bad idea to nuke the United States. Where we are."
 * The vast majority of Comic Book villains between 1930 and 1980 qualify, especially the ones made during World War II, where they really needed to convince the nation that the enemies of the USA were all dog-kicking, baby-eating, nuclear-war-mongering bastards.
 * Special mention should go to The Joker, where this seems to be his power. At many point, the Joker is simply Chaotic Evil bordering on Chaotic Stupid, and his M.O. can arguably be summed up as the definition of this trope. Only replace "evil" with "funny". Of course, The Joker is sometimes considered a Genius Magnificent Bastard. What is not up for debate, however, is that he is 100% insane.
 * Superboy-Prime also goes from Woobie, Destroyer of Worlds to this; he's a psychotic teenager with the Hair-Trigger Temper to end them all, though with a very strong Freudian Excuse. That notwithstanding, he flies off the handle at the slightest provocation and responds by destroying everything in sight and killing anyone who looks at him funny.
 * Norman "Green Goblin" Osborn had the world as his oyster during Dark Reign, with him in charge of the US security, the Avengers replaced with a team of villains loyal to him, and all the regular heroes incapacitated or wanted fugitives. But he just had to defy the President and go rogue and attack Asgard for some reason, losing everything and getting the good guys back in power in one day.
 * The fact that the Norse god of mischief tricked him into doing it explains, but does not excuse, his behavior.
 * The Monitors in Countdown to Final Crisis, whose plan makes no sense, accomplishes jack shit other than pissing off a bunch of other villains, and involves grandstanding to cover for The Mole even though there's no one for them to grandstand for. Then again, this is the Countdown to Final Crisis.
 * Any villain in Marvel who tries to rebuild, use, or - especially - upgrade the Sentinels. Ever since these monsters first appeared in X-Men #14, a wide variety of bad guys have gotten ideas about improving upon the original design, and almost without exception, the Sentinels malfunction, turn against whoever uses them, and become as much a threat to humans as they do to mutants, the upgrades often making it worse. You'd think someone would learn after a while.
 * Mammoth of the Fearsome Five:


 * Iznogoud, while displaying intelligence occasionally and being much smarter than both most people around him and the Caliph, still falls into this trope: a lot of his plans backfire precisely because he made idiotic mistakes, or couldn't resist the temptation to Kick the Dog at the wrong time.
 * Nicky Cavella tries to make The Punisher angry(er) by digging up the bones of his family, urinating on them and filming it. It works.
 * The mere existence of the Suicide Squad seems to be showing how much an idiot Amanda Waller is, seeing as she usually uses them to covertly clean up some other mess she started and lost control of.
 * In a story in the Batman: Streets of Gotham, third-rate villain Jennifer Duffy (aka the Carpenter) is hired by the Director to build a Death Trap complex with the intent to use it on Batman and film it, intending to market the footage as a Snuff Film. And he doesn't plan to stop their either, having "scripted" similar films with Superman and Wonder Woman as victims. He even advertises these movies. One movie poster shows Diana's dead body hanging from a gallows. Duffy's own opinion of this is, Batman is going to curb-stomp him, and she hopes to be paid and get miles away before that happens.

Fan Works

 * Dr. Brainstorm in Calvin and Hobbes: The Series rarely invents something that doesn't blow up. His sister Sheila barely even counts as an inventor.

Film

 * Evil Bill and Evil Ted from Bill and Ted's Bogus Journey. They try to run down cats while steering their time-traveling phone booth, just because. Of course, they are evil duplicates of the Stupid Good heroes, so it's no wonder.
 * The Umbrella Corporation in the Resident Evil film series seem to live and breathe Stupid Evil, not unlike the games they're based on. Their actions are geared entirely towards nothing more than propagating the existence of a deadly, uncontrollable virus that has no discernible practical applications.
 * A big problem in Johnny Mnemonic.
 * The thought of an evil Mega Corp profiting from distributing a cure for a deadly virus affecting half the world's population lacks the real oomf villains need, so they try to suppress it instead. However, they still want to go through the very specific trouble of cutting off and cryogenically preserving Johnny's head (the only remaining source of the data for the cure), even though they could just shoot him or completely destroy his head, and the cure would be permanently suppressed.
 * Of course, the bad guys are not immune to infection -- should any of them personally end up hit by the virus, they would need the cure. Also, it's stated that since the cure is cheap and requires only one dose, but the palliative treatment used to help disease-sufferers before the cure was invented is expensive and requires repeated doses, the corporations would genuinely make a greater profit by not distributing the cure. (Personally, I don't see how this works -- after all, the above calculation assumes that your entire potential market can afford the expensive version, which they probably couldn't -- but it's a plausible enough logic chain that the corp execs don't look like total morons for following it.)
 * Sebastian Shaw, the mutant villain of X-Men: First Class, plans to purposely start a nuclear war between the United States and Russia, resulting in humans killing themselves so mutants can rule the world. Yeah, plans that start with "start World War III on purpose" never end well. First off, despite being labeled homo superior, most mutants aren't much tougher than humans, meaning he'd probably kill as many mutants as he would humans. Even if they did outnumber humans in the end, what would be the point? All they'd have to "rule" over would be a nuclear-ravaged wasteland.
 * Marvel Cinematic Universe examples:
 * Ego the Living Planet from Guardians of the Galaxy, vol. 2. His goal was to destroy all mortal life in the universe in order to become the dominant species. Yeah, no-one's really certain what he'd do after that. Not only is this a stupid plan, it makes very little sense, as he previously claimed to be lonely, the reason he fell in love with a mortal woman.
 * Thanos from Avengers: Infinity War and Avengers: Endgame. For most of his career, the Mad Titan (who truly deserves that title, no matter how sick he gets of hearing it) considered himself a Well-Intentioned Extremist and Necessary Evil who claimed the only true way to save mortals from doing themselves in was to reduce populations of inhabited worlds. Gaining the Infinity Gauntlet gave him god-like power, able to complete his goal with a snap of his finger, but also made him the most hated and reviled man in the cosmos, as survivors had to watch family and loved ones turn to dust. He never considered that, maybe he could abandon his original plans and instead use this omniponent power to, say, construct more livable planets and heal existing ones, while providing them with infinite supplies of food and drinkable water. He'd have been viewed as a heroic savior instead of the horrific villain he became. Word of God has indeed admitted that Thanos is not as well-intentioned as he claims, and is desperately trying to prove that his previous plan could work to the point where it blinded him to all better options.
 * The schemes of some James Bond villains can be pretty dumb sometimes, and not just for the obvious reason:
 * Elliot Carver, the Big Bad of Tomorrow Never Dies. A media mogul who is the embodiment of New Media Are Evil he seeks to provoke a war between the United States and China to boost sales and ratings of his news divisions. This guy can actually blackmail the President, something he does as a Character Establishing Moment; if he has that much influence, maybe he could fulfill his goal by manipulating something with, you know, much less chance of extensive civilian casualties and global economic crisis? Not only does this plan get 007 after him, but China's equivalent, who eventually sides with Bond.
 * Gustav Graves, the Big Bad of Die Another Day. He plans to use his solar-powered Kill Sat to destroy the Demilitarized Zone between North and South Korea, so the North Korean army can invade South Korea. Even the guy's father - an actual North Korean general - realizes low ludicrous this is and the one-sided slaughter such a blatant violation of the treaty they hold would result in. Graves actually murders his father as a result, proving to everyone he's a bonafide lunatic.
 * The Wishmaster films, in a big way. The Jerkass Genie actually has motivation for his job: once the person who releases him makes three wishes, genies will be freed from the hell-dimension they're trapped in and rampage across the Earth. Time and again, however, he proves not just to be Obviously Evil, but also a unique combination of Stupid Evil and Chaotic Stupid. He could simply trust that the person who released him would have three things that they wanted to wish for - and the odds of that are pretty high - but instead, he insists on causing mayhem and destruction whenever someone makes a wish (particularly random people who aren't the person who can free the genies with three wishes), ensuring that whoever actually did free him will never make their three wishes.
 * It's justified, although it tends to depend on the movie. In all movies, granting somebody's wish effectively allows him to take their soul when they die (and the interpretations of these wishes usually end up with the person making the wish dead); in the third movie, it's mentioned that he needs 1000 souls before he can achieve his goal, although this detail wasn't present in the first two movies.
 * Helena Bonham Carter's version of Bellatrix Lestrange in the Harry Potter movies borderlines on this. She's portrayed as an insane character who delights in petty acts of vandalism like shattering windows and setting houses on fire. In the books, she's described as much more serious - she's considered insane only because of the level of her devotion to Lord Voldemort.
 * Super Mario Bros; man, where to begin here?
 * King Koopah's evil plan is to merge his world with ours so he could conquer it. Assuming this didn't cause two Earthshattering Kabooms, his world has only one settlement, Dinohattan, meaning he'd be facing off against multiple armies with his limited forces, and speaking of which...
 * Koopa raises the Surrounded by Idiots Trope to an art form. The police of Dinohattan are overworked, understaffed, and incompetent, Koopa's enforcers are the woefully stupid Goombahs, which were purposely made stupid via devolution, and he trusts Iggy and Spike to get the MacGuffin he needs. These two morons kidnap the wrong girl five times before managing to grab Daisy.
 * Also, for a totalitarian ruler, Koopa is rather careless, seeing as every citizen is armed, and weapons are lying around everywhere, just waiting to be picked up. Half of the movie is one big case of Boss Arena Idiocy, giving the heroes easy access to bombs, high-tech guns, and rocket shoes. (Which, in all fairness, are kinda cool.)
 * The Empire in Star Wars. Seriously, the oft-copied and oft-mocked thermal exhaust port that renders their "invulnerable" battle station completely vulnerable to a single proton torpedo wasn't something a smart organization would overlook. Some fans point out that the intent of Rogue One was to explain this, but in truth, it only made the Empire look stupider. Galen Erso might as well have had "Rebel saboteur" printed on his forehead, and once he was exposed as one, a smart dictator would have demanded every project he had been involved in checked with a fine-toothed comb. But again, the Empire is stupid.
 * The time lapse between Erso's being exposed as the traitor and the destruction of the Death Star is maybe 48 hours (remember that the ending scene of Rogue One is immediately before the start of ANH), and the Scarif facility holding the reactor plans has been destroyed and Erso's death makes the original designer of the reactor unavailable, so faulting the Empire for not re-examining all of Erso's work after his death is a bit unfair. They have no time to complete such an examination and arguably don't have a clean copy of the schematics to examine with.
 * The Big Bad in Catwoman is an evil cosmetics CEO who plans to market an anti-aging cream which has rather dangerous side effects: prolonged use makes the user's skin deteriorate and atrophy if use is halted. She thinks this will ensure customers continue using it and bring a constant cash flow. She never considers that the FDA would likely outlaw it first, nor the onslaught of lawsuits she'd have to deal with.
 * Deacon Frost in Blade. This vampire's Evil Plan involves turning everyone on Earth into vampires. Several more sensible vampires in the movie see the obvious flaw here - vampires prey on humans, and without them, they'd starve. Even if Deacon planned to keep supplies of blood in cold storage, it would be a limited supply, and he'd just be ensuring the extinction of his own people.
 * Loki does a lot of dumb things in The Avengers, but yelling at the Hulk was probably the dumbest. As anyone who knows the Hulk can tell you, insults never do much but make him angry, and the angrier the Hulk gets, the more dangerous and destructive he is. This ends rather badly for Loki.
 * Jerry in Fargo. He needs money (cause he's got none) and his scheme, being the Stupid Crook he is, consists of paying some other Stupid Crooks to kidnap his wife so his rich father-in-law will pay a ransom, planning to split the ransom with the hired kidnappers, a stupid and dangerous plan that works as well as you'd expect. Jerry also doesn’t notice some obvious warning bells, like his hired thugs bringing along “Carl”, someone nobody seems to know anything about. Sure enough, Carl is the one who messes the whole thing up.
 * Batman and Robin gave us two iconic villains turned into morons with another, “destroy the world without thinking about the long term” plot. Mr. Freeze plans to freeze the world so Poison Ivy can cover it with mutant plant life, so they can rule the world as Adam and Evil as Freeze calls it. The idea that two villains with such vastly different goals acting as a team is dumb enough without trying to consider what they'd do if they succeeded.
 * Die Hard was a great movie with great writing and an equally great villain, but one has to wonder why Gruber expected his escape plan to work. Surely he realized he couldn’t fit all his henchmen with their duffle bags loaded with stolen bearer bonds into that one ambulance? Even if he did get away, it’s obvious he’d be the prime suspect when the authorities found the empty vault, especially with no bodies indicating anyone died in the explosion.
 * Remember that the explosion was intended to kill all the hostages - the 'no bodies' problem would be solved by there being a whole lot of bodies, all blown to anonymous hamburger. As for escaping with the bearer bonds it's only necessary for the bags to all fit in the ambulance - the anonymous mooks can mingle with the crowd and exfiltrate on foot.
 * The Cabin in the Woods; while the SCP Foundation-wannabes in this movie are clearly kind of lax with their plan from the start, what ultimately dooms them when they're discovered is Dana and Marty hitting the system purge button, which releases every monster from their cells, who proceed to decimate and devour their former captors. Which begs one simple question: Why would they have this button in the first place?

Literature

 * The Forsaken from the Wheel of Time series pretty much ran the areas they were in charge of during the Age of Legend into the ground, because the only thing they were capable of doing was fighting. Asmodean, a relatively weak Aes Sedai, was made one of them because he only did things like kill all of his musical rivals, instead of feeding everyone to trollocs. When they were released from their prison, they didn't do much better. Most of the times they are seen holding the Idiot Ball, because they don't seem to understand that they can hold off on being evil for one day. Rahvin allows, and Sammael does such a poor job running Illian that the . There are implications that they were picked by the Dark One precisely for being people with huge issues.
 * And all the less important Darkfriends (anyone who pledges himself to serve the Ultimate Evil) are even stupider. They spend slightly less time committing evil than their Forsaken masters, but only because they're too busy dying like flies. If they're not being ordered off into suicide missions or being executed for failing other impossible tasks, they're being stabbed in the back by their rivals or casually tortured and killed just for being in the wrong place when somebody important has a temper tantrum. And to add to the Stupid Evil of it, they all earnestly believe that they'll get the immortality and infinite power they were promised, even though the Ultimate Evil hasn't given that to anyone in over three thousand years.
 * Jordan himself noted that much of the Forsaken's behavior and group dynamics are based on Nazi internal politics, a group notorious for being really good at out-backstabbing one another and not so good at running things. Of the Forsaken, only Ishamael cum Moridin has a deeper more philosophical understanding of the nature of oblivion and the Dark One's seeming true goals; he is arguably the most dangerous because he isn't selfishly evil and is much more deeply nihilistic.
 * Draag, the Dark Paladin in Game Night by Jonny Nexus, plays Stupid Evil to the hilt, as his answer to nearly every problem is either A) Pull out his evil sword DeathSinger and stab it or B) Pull out his evil sword DeathSinger and torch it. The opening chapter has the GM/God of the world having to rewind time several times as Draag first stabs a gatekeeper before he can tell them the riddle they need to solve to get past, and then stabs the gatekeeper after he delivers the riddle, but before they can answer. Then, once they do solve the riddle, he kills the gatekeeper anyway.
 * Clandish "Cybomec" Consto in Stationery Voyagers. Astrabolo of the Yehtzigs is even worse.
 * The scorpion in The Scorpion and The Frog is the Ur Example.
 * Joffrey Motherfucking Baratheon. Crown Prince of Westeros, and a spoiled brat with way too much power. He hrows his royal weight around whenever he possibly can, openly mocks everyone regardless of their standing or authority,.
 * Also Ramsay Bolton. His father discusses this trope in A Dance with Dragons, pointing out the foolishness of his son's openly cruel ways.
 * Tak from Stephen King's novel Desperation. It murders an entire small town for kicks, despite needing a fresh supply of human hosts in order to survive. (To make this even more absurd, the town in question is in the middle of the desert.) The characters even come to this conclusion when they question its actions.
 * Voldemort in was the feared and dreaded symbol of Pure Evil in the Harry Potter franchise, and also one of the stupidest villains in modern fiction:
 * For the record, the whole franchise would never have happened had he not failed in his first attempt on Harry’s life due to a - misinterpreted - prophecy. The biggest reason he failed to kill Harry as an infant was because Lily sacrificed herself to save her son, but in hindsight, did Voldemort really need to kill Lily? If he had instead used the Cruciatus Curse to subdue her (or frankly, even just pushed her aside) he’d have had a clear shot at Harry. Killing Lily not only fouled up later attempts to kill Harry, it gave Harry a valuable ally, and speaking of whom…
 * Snape’s crush on Lily was sort of creepy, but using a For Want of a Nail scenario, Lily’s death was the sole reason Snape turned against him, giving Harry a potent ally. While Voldemort’s most stated weakness is his inability to comprehend concepts like love and friendship, he does know a thing or two about loyalty, pride, and holding grudges. He should have known Lily’s death would enrage Snape to the point of desiring revenge, and for all his jerkass tendencies and uppity attitude, Snape is a competent and very powerful wizard, not someone you want on your bad side if you can help it. Indeed, had Snape remained loyal to Voldemort, it is very likely Snape would not have gone out of his way to save Harry during the Quiddich match where Quirrel booby-trapped Harry’s broom, ending the young hero’s career in his first year.
 * One of the reasons heroes with capes and masks use secret identities is because of a common trick bad guys use to get to the good guys, trying to do them in through their family and friends, but even though Harry has neither cape nor mask, he has plenty of allies he cares for who depend on him. Ron, Hermione, Ginny, and Dobby, to name a few. Yet, this is something Voldemort rarely tried. He did it once, in The Order of the Phoenix, sending Harry visions of Sirius Black, and it worked; how hard could it have been to expand this theme? Especially seeing as Hermione’s parents are both muggles, how hard could it have been for him or another Death Eater to kidnap her during summer vacation?
 * One of his biggest mistakes was making the conflict with Harry a personal issue. Sure, Voldemort is an evil wizard, and it’s understandable that he’d blame Harry for having to share Quirrel’s body, feed on unicorn blood, and  looking, well, hideous. And he believed a prophecy about being the only one who could kill Harry. But frankly, he could have survived had he just let go a little. His vendetta was an obsession, and his insistence on doing Harry in himself is the biggest reason the Boy Who Lived, er, lived as long as he did. Due to his orders, his followers were goofing around giving the students cursed diaries rather than make any steps towards eliminating Harry, and even when he did come back, his “leave him to me” mentality only helped Harry escape, often with far more information than the villain would have liked.
 * His entire plan in Harry Potter and the Goblet of Fire. Here's the problem: You need the blood of your enemy to restore your physical body. So you decide to convince Barty Crouch Jr. to kidnap "Mad Eye" Moody, brew a year's supply of Polyjuice potions, have Crouch infiltrate Hogwarts disguised as Moody, teach the Defense Against Dark Arts class for a year (giving Harry and his friends some very useful info about combating black magic), manipulate the Goblet to compel Harry to compete in the Tri Wizard Tournament, push Harry in the right direction during said Tournament, and finally, turn the trophy into a port key that delivers Harry into your clutches. Well, it works, but wouldn't it have been a lot easier to just enchant his toothbrush or something? In the end, Voldemort's whole plan seems to be a whole lot of unnecessary effort and cost for something that, on the surface, he could have done easier.
 * Not to mention, if he really needed blood of an enemy, the dead body of poor Cedric was right there, but Voldemort was so hung up with his obsession with Harry to consider that option. In fact, the only folks who didn’t qualify were the Death Eaters. Even Pettigrew (you know, the guy who thought spending three years as a rat was a valid plan?) thought this was a bad idea.
 * There’s also his complete inability to use subtlety in his assaults on Potter. Despite what Dumbledore would have you believe, Hogwarts’ security, to be blunt, stinks. Sirus Black (a fugitive convicted of murder who had just broken out of jail) was able to sneak in, vandalize the fat lady’s painting and get away before anyone noticed, Rita Skeeter spied on numerous staff and students in order to write her slanderous stories, and Peter Pettigrew spent three years in the students’ dorms disguised as a rat before anyone noticed. Had Voldemort actually tried to sneak in himself after Goblet of Fire (or had one of his minions do it) possibly using a Polyjuice potion to disguise himself as Ron, Hermione, or for that matter, anyone Harry trusted, it would have been all over. But each and every time he confronted Harry, he had to make a big show out of it, giving Harry the chance to escape or fight back.
 * A point often brought up by fans is how big part of defeating Voldemort lay in finding and destroying his Horacruxes, but it seemed he made them WAY too easy to find. Why not sink one in the middle of the Pacific Ocean or bury another in Antarctica? It isn't hard to imagine that Godric Gryffindor himself would be challenged if he had to find them there.
 * Another missed opportunity, the Unbreakable Bond. This spell places two wizards into an agreement that will kill one of them should he break it, and it seems surprisingly easy to cast. Fred and George nearly made one with Ron when they were just kids, so it’s absurd to think Voldemort couldn’t have used it to prevent his own minions (including Snape, Karkaroff, and the Malfoy family) to prevent desertion and/or betrayal, but he seemed content on using the Black Mark, which in the long run, did little to ensure loyalty.
 * Good old lovable idiot Horace Slugthorn, the guy who inadvertently told Tom Riddle about Horacruxes in the first place. Poor guy was paranoid that the Death Eaters would try to silence him, but one has to wonder, did they even try at all? One would think Voldemort would put at least some effort into eliminating this dangerous loose end, but no, Slugthorn not only lived long enough to retire, but come out of retirement, and eventually give Harry the info he needed to take down Voldemort.
 * And finally, there’s the Time Turners, a major plot device (and a lot of wasted potential) in Prisoner of Azkaban. This device was invented by Lucius Malfoy (one of the Death Eaters), and despite how powerful it was, seemed easy to get, given how many the Ministry of Magic had. Sure, there are rules governing their use, but when has Voldemort cared about that? He had so many chances to grab one, and could have used it to undo any of the mistakes he made on this list, but it never seemed to occur to him.

Live Action TV

 * Sylar and Elle of Heroes: Elle is bored on their first mission date and decides it would be fun to kill the rental car guy. Sylar gets one after killing four people in broad daylight and then not even trying to hide all that blood.
 * Also, Peter Petrelli during his brief Face Heel Turn phase after absorbing Sylar's ability and its corresponding psychosis. In comparison, Sylar, for his part, is perfectly capable of faking being normal if it will advance his long-term goals, and may even occasionally show mercy if the mood strikes him. Evil Peter, on the other hand, had No Indoor Voice and was instantly compelled to decapitate every single person that he met after he gained Sylar's craziness.
 * Doctor Who examples:
 * Let's start with the Big Bad himself, the Master. He seems to want to take over the universe for the fun of it. In "Logopolis," he not only accidentally kills octillions of people, he draws attention to himself by randomly killing a policeman and The Doctor's companion's aunt. This is caused by the extreme Flanderization he went through soon after his first appearances.
 * The Rani calls him on this: she just wants to rule one planet, beneficently if she can get away with it — but what are you going to do with the Whole Universe?
 * The new series attempts to rectify this by making the destruction of his homeworld and his species in the Time War the motivation to take over the universe, and giving him a Freudian Excuse as motivation for his more psychotic actions. Its success is debatable, although, as he still enjoys killing lots of people just for the hell of it.
 * Alternatively, this has led to the completely serious fan theory that the Master is evil simply to get the Doctor's attention, in the manner of the stereotype of a boy pulling the hair of a girl he likes. After all, why would he consistently target the Doctor's favourite planet?
 * The most likely explanation, offered by the new series, is that while he claims to want to conquer the universe and have big plans, he is simply driven to acts of destruction by the pathology that started when he looked into the Time Vortex and the sound of drums filled his head.
 * The Daleks: Sure, these things are pure Nightmare Fuel for anyone who grew up watching Doctor Who, but in retrospect, you might actually be ashamed of yourself for ever being scared of them. They’re pretty dumb, for a variety of reasons; and would be candidates for a racial version of the Darwin Awards if they just did the universe a favor and stayed dead for once. Note that, to be fair, a lot of this can be blamed at least partially on Davros, who created them with a flawed design:
 * For starters, while they claim to be "superior" to every other species, the design of their cybernetic exoskeletons is just plain... wrong. A lot of jokes have been made about how, in early episodes, the only handicap they had that was worse than their inability to maneuver up a set of stairs is their even worse inability to maneuver down a set of stairs. Later incarnations managed to correct this with levitation devices, but they had other problems. Their optic-sensor-on-a-stalk has always been another Achilles heel: it gives them absolutely no peripheral vision or depth perception, and they have to rotate their entire bodies simply to look around. You could theoretically run rings around a Darlek as it was struggling even to get a bead on you with one of its weapons. The Doctor famously blinded one of them with his hat in one episode, and this Troper is fairly certain there was at least one episode where a Companion did so with a wad of chewing gum. Some of them have a sensor ray to correct the first problem or can heat the eyepiece to remove any foreign material, but the only Daleks who use these additions are the ones who must survive for sake of plot. Also, that plunger-arm they have is pretty good for draining knowledge from a victim’s brain or information from a computer, and their manipulator-arm is useful as a cutting tool, flamethrower, or seismic detector, but both are downright terrible for turning pages in an ordinary book, opening a door with a key, or any other task that requires fine manipulation or opposable thumbs. Their gunsticks are powerful weapons, but would be even better if they didn’t have to swivel their entire bodies simply to aim them. A Dalek can move almost silently, so a smart one would try to sneak up on their victim while using a weapon like this, but Dalek’s can’t help but scream “EXTERMINATE!” all the time at the top of their lungs in their squeaky, scratchy, jarring voices, making them unable to sneak up on anything with a sense of hearing. It is discovered later (earlier?) that this is a command word that reloads the weapon, but that just adds another design flaw. They used to have a “dry ice gun” (which they were eventually smart enough to stop using) a deadly weapon designed for close range, a type of combat  no sane Dalek would engage in. In short, the only reason their invasions ever succeed is because in this series (like many others) Earth’s armies  consist of soldiers with no fight-or-flight response. Usually, that is; some ordinary soldiers can trounce them pretty well. Worst of all, they tend to technologically regress every time they have to rebuild their civilization, and speaking of which...
 * Daleks also have a self-imposed Hive Mind (sort of) that links them all through a data-sharing network (the Pathweb), but the efficiency of said network borders on pathetic. In one episode, Clara manages to hack into it and delete all knowledge of the Doctor’s existence, and it took her all of five seconds. ("Doctor… who?? says a puzzled Dalek afterwards.) Sure, this was the mistake of an “imperfect” Dalek who was later killed, but it seems they discover and “EXTERMINATE!” members of their own kind for being “imperfect” at least twice per episode where they appear. Still, the problem with Pathweb is mostly an extension of their individual brains. Designed only to hate other races and destroy what they hate, and showing any positive trait or emotion other than hate (like showing mercy, gratitude, or generosity) will mark a Dalek for death by its Social Darwinist kin. The Doctor and his Companions also discovered quickly that the best way to confuse a Dalek is to spout nonsensical babble; they're struggle to make sense of it  until they panic out of frustration. Something they do a lot, actually, screaming and shooting their weapons blindly (often falling down stairs!) if a plan goes sour. It’s a miracle these things survive long enough to reproduce, and speaking of which…
 * A Dalek’s biological make-up is the biggest reason they’ve been “brought to the brink of extinction” so many times, due to their own biological experiments and relying so much on the exoskeletons. They cannot reproduce on their own, and creating new Daleks requires technology and genetic material from other beings. Usually Davros (someone they have grown to hate) does this, but they have been known to plead for the Doctor to aid them too, and even when he does, they never show any gratitude. One has to wonder what would happen if they succeeded in obliterating all other races; they’d likely die out, either from this inability to create more or turning on each other, and speaking of which…
 * Possibly the Crowning Moment of Stupidity for the Daleks came with the Cult of Skaro, a group of four Daleks designed to research methods and strategies that most Daleks found unorthodox. Selected by the Dalek Emperor, these four Daleks were allowed to have individuality, even having names, and were allowed to base their ideas on emotion and imagination without fear of consequence. One of them, Dalek Sec, has since become known as the smartest Dalek who ever lived, for good reason. He did indeed get some clever ideas, which enabled him to rescue millions of other Daleks from a Time Lord prison. He figured, to paraphrase, "Wait, if humans are inferior, why do we keep losing to them?" He then proposed combining their DNA with that of humans, using himself as a test subject; as a result, he became smarter and stronger, even to the point where he could function without his cybernetic armor and freeing himself of every flaw mentioned above due to the ill-conceived design. For a while, it seemed there was hope that the Daleks could prosper. But despite the positive results of this experiment, the other members of the Cult saw Sec’s ideas as blasphemy and murdered him, and act that led to the Doctor quickly killing two of them. Only Dalek Caan survived, only to again put his species back on the same unending cycle of hatred and failure. In fact, the next time the Daleks came close to extinction, it is heavily implied Caan's insanity had led him to do it on purpose.
 * What’s more, Dalek schemes tend to show ridiculous incompetence. Say a story ends with the Daleks having dwindled to a dozen or so due to their last defeat and the above-mentioned problem. Their plan will start by finding a way to replenish their species, but before their race is even close to recovering, they’ll launch their genocidal campaign again, eventually bringing them right back to where they were before. They also suffer from the flaw of all arrogant and overconfident villains, telling the hero every minute detail of their plans and giving what he needs to figure out the flaw in them, something a supra-genius Time Lord can do pretty quickly.
 * Davros, aside from the aforementioned faulty designs and his stated goal to "DESTROY ALL OF REALITY!" and assuming there are benefits to it, usually avoids this Trope. However, one lesson he simply refuses to learn is that the Daleks will always double-cross him, something they do every single time he works with them. It's almost become a Running Gag with him.
 * Any vampire who attacks Buffy the Vampire Slayer, knowing who she is, instead of running away from her. Newly-turned vamps who are unaware get a break.
 * Exceptions can be made for any vampire legitimately powerful enough that their odds of taking a Slayer in hand-to-hand are respectably high (such as the Master, Angelus, or Spike), but vampires that tough are anything but common.
 * In detective shows, anyone who commits a crime when they're aware that the famous detective is in the area.
 * In the CSI episode "Bad to the Bone", the killer is close to this (he's shown to have a short temper and be extremely violent). He steals poker chips (and never cashes them in despite having thousands of dollars' worth), starts fights (in which he beat a man several times his size to death with his bare hands) and then walks into a diner covered in blood to wash his hands and order a sandwich.
 * While he's not the only example in the series, he's the only one who doesn't have the excuse of being on drugs or a stupid kid.
 * Dear God, the Borg. While dreaded and feared in Star Trek mythos, a combination of poor design, lack of creativity, inability to adapt, and lack foresight makes them absurdly easy to outsmart. A supercomputer is no good if it uses no firewall or antivirus, and the Borg takes such an analogy Up To Eleven. They never prepare for stealth-based viruses and sabotage, never learn from their defeats from such, and never seem to come up with new ideas on their own. They're unable to even see beings not registered as threats, meaning you could waltz right into one of their giant cubes, plant a nuclear bomb, and leave without being caught, so long as you made no threatening moves. Seven of Nine's parents lived and studied them right under their noses for two years before being caught, and they didn't even learn from that. They also never bother to study the history of the races they assimilate; Picard was able to mow them down with a tommy gun in one episode involving the Holodeck, something that should have been the equivalent of an American soldier standing up to a Blitzkreig with a squirtgun. How they ever became powerful enough to be considered The Dreaded in the first place is a mystery.

Professional Wrestling

 * Any ally of a heel wrestler challenging a face champion for a title who will enter the ring and strike the champion for no apparent reason, thus getting their partner disqualified (though this actually makes sense if the heel is the one who is champion, since a champion can get disqualified and still keep the title). Sometimes the interfering ally will weakly try to justify this by claiming to have wanted to "help" his friend, which is not only completely ridiculous but kind of insulting as well, particularly if the challenger who was just "helped" is the interferer's superior.
 * Of course, since Professional Wrestling matches are completely scripted, actions such as this are more for added entertainment than due to genuine stupidity.
 * More recently, the ally will usually at least try to wait until the ref's back is turned to do something. Of course, also recently, the ally will usually fail in their effort and end up getting their ass kicked.
 * Kane kept falling into this pattern of behavior when he was trying to get John Cena to "Embrace the Hate" in the course of their recent feud. Although his long-term plan was to poison relations between Cena and the "Cenation" (his fans in the stands) and then between him and his friends Zack Ryder and Eve Torres (and this plan proved partially successful), Kane just could not restrain himself from attacking and maiming Ryder (or further maiming, since he had already put Ryder in a wheelchair) simply because he could, which only shifted attention away from Cena's ambivalent relationships with his allies and motivated Cena to oppose Kane all the more.

Tabletop Games

 * In Warhammer 40,000, the forces of Chaos (appropriately enough) make some pretty questionable tactical decisions from time to time, including sacrificing hundreds of their own cultists for purely symbolic reasons (as opposed to sacrificing hundreds of cultists for perfectly practical reasons, like summoning daemons, bigger daemons, and really really big daemons to attack their opponents). In addition, infighting between various Chaos factions has spelled the ruin of more than one attack on the Imperium. It's not for nothing that their symbol is eight arrows pointing in different directions.
 * Don't forget diverting shock troops in extremely rare and strong armor, even by Space Marine standards, from a strategically important battle to take out an enemy propaganda station run by a dozen unarmed monks, then annihilating it from orbit while the shocktroops are still inside. Chaos commanders seem to have a collective inferiority complex or something.
 * A specific example: Kharn the Betrayer is such a bloodthirsty, frothing Ax Crazy that even his fellow Ax Crazies don't want to get anywhere near him. This is because he has a tendency to slaughter friend and foe alike when his blood is up. Justified in that Kharn is fanatically dedicated to Khorne, the Blood God, and Khorne cares not from where the blood flows, so long as it flows. Kharn is particularly notable among Khornates because he lacks even the very rare pragmatic tendencies they do exhibit. The source for the quote at the top of the page? The quote on his page in the Chaos Marines Codex.
 * At one point, when the World Eaters (Kharn's legion of Chaos Space Marines) were attacking an enemy force of Emperor's Children (another Legion of Chaos Space Marines that worship Slaanesh), a blizzard so terrible even the genetically-enhanced and daemonically-powered Super Soldiers couldn't take it descended and forced both sides to retreat into shelter. In a fit of rage, Kharn burned the World Eaters' shelters to the ground and proceeded to run around in a psychotic frenzy, slaughtering anyone that came within chainsaw-axe range. Both Legions suffered such horrendous casualties that they were never again able to take the field as a unified fighting force, and are now reduced to fighting alongside other Chaos warbands as shock troops. Thus, as far as his faith is concerned, he was doing the right thing and all the other World Eaters where being cowards. This is represented in the tabletop game by Kharn's special rules: if you roll poorly to hit in close combat, where any other character would simply miss, Kharn instead hits someone on his own side.
 * Dark Eldar love torturing stuff. Technically, they do have a reason, as they do it so that the evil god their ancestors ended up creating won't eat their souls, but besides that, they just love torturing people for fun (especially when you consider that such actions created the thing in the first place). So much so, in fact, that their vehicles are designed for swooping in, grabbing prisoners, and zooming off into the sunset at the expense of all else -- including armor and crew & passenger protection, though not necessarily firepower.
 * The Skaven of Warhammer Fantasy Battle Fantasy are very much Stupid Backstabbers. While this serves a useful purpose in ensuring only the strong survive, this isn't saying much since Skaven take the We Have Reserves and Zerg Rush approaches; on the other hand, their tendency to turn every minor engagement into a five-way leadership battle is pretty much the sole reason apart from sheer troop inadequacy that they haven't taken over the entire friggin' world. Seriously, in one of the Gotrek and Felix novels, Thanquol could have won by page 200 if he hadn't been sending the heroes to eliminate his rivals out of fear for his position.
 * Dungeons and Dragons examples:
 * Drow elves in most campaign settings. Being forced to live underground, surrounded by swarms of magic-eye-beam-firing, mind-controlling, acid-spewing and other nastiness-causing beasties? Sure, why not worship an insane demon and turn your own civilization into a Social Darwinist nightmare so you expend three-quarters of your energy fighting yourselves? Of course, the Drow pantheon in most settings has an Ax Crazy Goddess who rules their society and demands that they constantly double cross each other. She is specifically described as "constantly watching for signs of too much cooperation", and must also rein them in when they inevitably go overboard.
 * Though she encourages a lot of the backstabbing and plotting, the problem is without her, they don't quite stop backstabbing as such. She at least keeps it from escalating into large scale bloodbaths or otherwise threatening their cities as a whole — via civil wars of large cohesive factions, cooperation with outside forces against their kin, unrestrained mass destruction, etc. Without a divine guidance specifically addressing this problem, the drow would be inclined to walk closer to the edge of extinction - and, at least in Forgotten Realms, explicitly did, more than once! This is not unlike the tendencies of other elves despite their own divine guidance — which is naturally much more benign, but not helping with the persistent fatalist problem. With her, it's not all pretty, but they still have enough of an excess population (which is capped hard, as the drow are a Terminally Dependent Society living in caves, after all) to waste in raids on others. So she steers them toward a less stupid sort of evil.
 * Of course, the Drow are far from alone amidst evil D&D monsters and villains here. In fact, some of the most blatant examples are human (many of the Zhentarim in the Forgotten Realms come to mind) -- in this case, their individual evilness may be unconsciously or deliberately played up because they have no convenient "monstrous" traits to clearly mark them as Obviously Evil otherwise.
 * The Zhentarim can at least replace their casualties from the general run of humanity, which is how they survive having an internal casualty rate as high as they do. The drow are a separate race as well as a political faction; if their fratricide damages their gene pool beneath the threshold of viability then they're done, because they damn sure ain't picking up any new drow from elsewhere.
 * Any mortal spellcaster who makes a habit of summoning demons qualifies. Sure, it might be possible some of the smarter ones have dark secrets such mortals could use, but with the possible exception of Pazuzu and maybe Graz'zt, demons do not make deals with mortals (that's what devils do), they're just too chaotic and rarely do anything but destroy. And an evil wizard who summons them too much will eventually make a mistake causing the summoned demon to break free, which will certainly create a lot of destruction.
 * And for that matter, demons are this. Their stupidity laced with insanity is the Order Versus Chaos Blood War between Devils and Demons has been in stalemate  for Eons, despite the fact that the demons of the Abyss outnumber the armies of Hell by almost a hundred to one. The devils live and breathe discipline, planning, and strategy; while the hordes of the Abyss can be explained in three words: "Scream and charge". It's telling that the Abyss and its demons are functionally infinite, so its armies in the Blood War are only the rare few who overcame their chaotic nature to the point that they could scream and charge at the enemy.
 * Intentionally employed in the Paranoia RPG system, where all of the player characters are supposed to be stupid evil and the "plot" is just an excuse to put them all in one room while they try to out-backstab each other. Not only that, but they're all at the mercy an omnipresent Lawful Stupid NPC, Friend Computer, so that have to try get away with being Stupid Evil while acting like they're Lawful Stupid.
 * World of Darkness as a whole seems to always have a Stupid Evil faction for the players to fight against (or join). In Vampire, we have the Sabbat, who want to rule over humankind openly, ignoring that the Camarilla, their opposing faction already basically rules the world. In Werewolf, we have the Black Spiral Dancers, who would really really like to help the Wyrm destroy the universe. And finally, for Mage, we have the Nephandi, who want to help Demons/The aforementioned Wyrm/Every other otherworldly abomination destroy the universe basically for the lulz.
 * The New World of Darkness has its share as well, most notably Belial's Brood in Vampire: The Requiem.
 * Lampshaded in the Mage: The Sorcerers Crusade supplement Infernalism - The Path of Screams: "Here comes my Dark Lord! Booga-Booga-Booga!" "No, you don't - taste my steel!" SPLAT! End of story, right? Not if you do (Infernalists) justice." That passage goes on to describe complex and intelligent motivations and behaviors for Infernalist antagonists.
 * Subverted with Exalted and the Infernals... most of the time, anyway. Even after offering their souls to the Yozi and merging with a demon, most Infernals are at least practical in their quest to turn Creation into a living hell. That being said, Infernals are expected to be paragons of demonic will while they are in Malfeas, and participate in baby-eating contests and the like.
 * Side note: you can commit super-villain style antics, such as telling the heroes about your magnificent plans, kidnapping maidens (or men), or setting up elaborate death-traps in order to reduce your Limit (and avoid the wrath of your demonic overlords). In other words, the game encourages you to be Stupid Evil, at least some of the time.
 * The Rakdos from the Magic: The Gathering Ravnica bloc are this intentionally. They even draw a great deal of their strength from mindless slaughter, which is also reflected in their representative gameplay mechanic (Hellbent).
 * The Gruul might also be either this or Chaotic Stupid, depending on who you ask. They have good reason to be pissed, though: Backstory tells that when the guilds were first formed, the Gruul were put in charge of "protecting nature." The problem is that Ravnica, their setting, is a plane-wide city, so between having much of their purpose being co-opted by the other Green-based guilds, or just eliminated by urban planning, they were eventually cast down as a guild. They didn't take it well.

Video Games
"Lilarcor: I don't know what you were expecting, but as a sword I'm pretty one-dimensional in what I want."
 * Arcanum is a perfect example. Most evil actions fall into the Stupid Evil category. For example, you recover a wedding ring for a person who offered you 200 gold for it; the wedding ring is worth 30 gold in the pawn shop. The good option is to sell him his ring for 200 gold; the evil option is to murder him (and not get any money since he doesn't carry it on him). Almost every single morality choice in the game is of a similar vein.
 * The textbook video game example is Morrigan, from Dragon Age: Origins. She's supposed to come off as merely practical and ruthless — but given that she actively suggests you screw over other people who you need to defeat the Blight, encourages betrayal and being a prick to people whose aid you need, and in general, just being a snarky asshole, she comes off as Stupid Evil. The most blatant example of this may be the fact that, as an apostate mage who has lived her life on the run from the Templars, she approves of helping the Templars kill off Ferelden's entire Circle of Magi... because they allowed themselves to be shackled by the Templars in the first place.
 * Justified and played with in that Morrigan was raised to be Stupid Evil -- because her mother Flemeth is an enormously powerful and smart evil, who needs Morrigan only for her body (that she intends to eventually take over), and having Morrigan become competent and develop her own independent powerbase in the interim is not on her agenda. However, Morrigan still has to be evil and not just raised to naively be a good person who believes everything her mother says, because nice trusting people often make friends without even trying and friends are people who fight Flemeth to save their friend's life. And so, Stupid Evil. (Admittedly, the PC ends up fighting Flemeth to save Morrigan's life anyway so the plan doesn't quite work, but you have to give Flemeth credit for trying.)
 * Completely averted in Planescape: Torment. You can try to be Stupid Evil, but this just gets you a visit from Sigil's resident Physical God, the Lady of Pain. You get many, many chances to be a highly intelligent Manipulative Bastard, bordering on Complete Monster, though, and the Practical Incarnation, probably the smartest of your previous incarnations, was easily both.
 * Can be played straight, averted or even subverted in the first two Fallout games. While it's quite possible to go through the games killing nearly everything that breathes, many of the "evil" sidequests can be accomplished without wholesale slaughter or dog-kicking malice, and many of the "good" sidequests can be solved with needlessly violent acts as well. Need to get a hostage from the slavers? Don't bother negotiating a deal that benefits everyone, or seducing the leader. You can just kill them all! An evil-pacifist run isn't entirely impossible, just annoyingly difficult.
 * To be specific, in Fallout 2 the most ideal ending for New Reno, where it stops being a Wretched Hive and becomes somewhere you'd actually want to live, is gained by wantonly killing everyone save the Wrights (and not becoming a made man with the Wrights, since this will lead to the Wrights using the military tech in the Sierra Army Base to create a military dictatorship).
 * Or you can simply cloak-and-dagger tactics to eliminate the heads, each being a case of being Hoist By Their Own Petard; each New Reno head have a way to die without pissing off their fellow family members.
 * A common criticism of Fallout 3 is that, while the game allows you to play "good", "neutral" or "evil" characters, the Karma system much more frequently gives you "good" points for completing quests. It's virtually impossible to become "evil" or even remain "neutral" by playing just the main quest. Therefore, the only way to be recognized by the game as "evil" is to be an unthinking sociopath, literally going out of your way to be a dick, paying no attention to what you're actually supposed to be doing, and in the process engaging in numerous acts that are unnecessarily risky. In other words, the same thing as Neverwinter Nights mentioned below.
 * Some of the main quest "evil" choices make no sense even from the perspective of immoral self-aggrandizement and can only be justified by misanthropic, psychopathic stupidity. The extra caps given for doing the evil options are usually a pittance and in many cases even major rewards aren't worthwhile. What's more valuable? A house in a well placed settlement on several major routes throughout the wasteland (good reward) or an apartment on the extreme edge of nowhere that is under siege by ghouls (evil reward)?
 * Fallout: New Vegas is much better about how evil you really can be, but still a bit stagnant. Legion playthroughs and quest chains amount to about 1/3 of the content of a NCR or House friendly Courier. Granted, New Vegas also reduces the importance of Evil Karma, but at the end of the day you'll probably end up mindlessly gunning down every NCR soldier you can, followed up by gunning down most civilians who are happily aligned with NCR.
 * New Vegas also featured Fallout 3's weird bits of random karma for killing certain NPCs. In particular before being patched, killing randomly encountered(fixed location, but they respawn) Fiends would give you something ridiculous like +100 Karma per kill. If you've spent the entire game as the sickest bastard in the Mojave, your first trip down the west side of outer New Vegas can turn you into a saint in as little as two shoot outs.
 * Storyline example: Vault-Tech, the Predecessor Villains of the franchise. Sure, tricking so many people into becoming human guinea pigs for experiments might be considered smart, assuming the experiments worked, which they did not. Some of the experiments might have been useful - if unethical - for biological research and social experiments, but others seemed absurd and silly, like a vault populated by one man and a thousand women, and the one with one occupant and a box of puppets. Plus, it seemed the Vault-Tech leaders never planned to build a Vault for themselves, because as far as is known, none of them survived the nuclear war that they claimed the Vaults were built to shelter customers from.
 * IIRC, the Vault-Tech higher-ups were betrayed by their superiors, the Enclave. Which makes sense; they might have been useful in the setup phase but who wants to actually have these lunatics still around during the post-apocalypse.
 * Street Fighter ha M. Bison. Not only does he aspire to Take Over the World, not only does he routinely tell the hero that Soon I Will Be Invincible, he also routinely betrays his own freaking underlings, most of whom would be perfectly happy serving him if they continue being paid (Balrog) or if they get to keep fighting/killing (Sagat and Vega). Incidentally, Bison's lackeys usually turn against him and kill him in their (generally non-canon) endings.
 * Guilty Gear: I-No is a dumbass who frequently causes huge messes in the name of That Man. Not only do said messes more often than not have nothing to do with what he wants, but he usually has to clean up after her. As such, it's really quite surprising that he even still lets her work for him.
 * Most of the things you have to do to get 100% corruption in Overlord are just For the Evulz and grant no practical benefit. The most blatant example is the last peasant-killing requirement, which can only be reached by repeatedly reloading one of the town areas to spawn more villagers to kill.
 * The sequel's 100% destruction path is the same. Among other things, you're required to kill off all the people in your own towns instead of making them work for you. Since the game is not that serious, however, it's not that much of an issue. It also helps that, unlike the original Overlord, you are rated on "destruction" vs "conquest" instead of "Good" vs. "Evil". Enslaving people is "conquest", and slaughtering towns is "destruction", so you are not actually forced to be stupid evil if you don't want to.
 * Many of the options for "Closed Fist" in Jade Empire fell under "Kill people or trick them into killing others or themselves just because you can." However, more memorably and in something of a subversion, many of them actually offered the opportunity to provide interesting justifications; you might not just kill the fox spirit protecting a forest because you could, but because her weakness in allowing evil to taint it was a sign she wasn't fit to guard it anymore... or have a girl who was about to be sold into slavery kill her would-be buyer to teach her that freedom is worth fighting for.
 * It is worth noting that if you get your Closed Fist meter to maximum, the dogs which can be seen walking around the city become targetable. Yes, once you're pure dang nasty evil, you really can Kick the Dog. When you kill them, they drop health powerups! It is further worth noting that if you're in the city where these dogs are, you could also find chi and focus altars that instantly restore their respective energy bars. Even if you get into a fight near a dog, but far away from any altars, you can force enemies to drop any powerup on death. Thus, this action is purely For the Evulz, serving no purpose and offering no benefit to the player.
 * In the game Harvest Moon DS, to marry the Witch Princess, the player has to kill 50 animals (which cost a lot of money to acquire, and then make the player a lot of money in return), litter in the road and poison the stew pot at a festival (which makes everyone else in the valley hate you, naturally), and pass out from overwork 100 times (which costs time and money, again, as passing out will cause you to go to bed immediately and lose half of your gold). Surely there are easier ways to prove that she's evil besides making you play the game horribly to make her like you?
 * The Demon Path of Soul Nomad and The World Eaters. Once you beat the game normally, the New Game+ option opens up to play the game evilly. And boy can you. As a baby-killing, genocidal monster whose only goal is to kill everyone in the most painful way possible, the characterization lies not in you, but in the previous timeline's villains who have to deal with you being Eviler Than Thou. Some actually turn good in this timeline, having joined forces with the heroes opposing you and discovering they like it. Others are still evil, but are scornful of the pointlessness of your actions or are eventually driven mad just by being around you.
 * Wario occasionally. For example, the trouble he has to deal with in Wario World happens after he steals the Evil Black Jewel. Honestly, who'd be dumb enough to steal  something like that? Well,  Wario, obviously. He even admits he had always been a little suspicious of the thing.
 * Lilarcor from Baldur's Gate II is Stupid Evil personified, seeking only to kill everything the party meets — and he's a sentient sword, with a personality apparently based on a fantastically stupid hick, which fortunately means he's incapable of doing anything on his own.
 * But then, when all you are is a sword, all problems look like stab victims.


 * The Baldur's Gate series in general. Most often, the 'evil' dialogue and quest choices have you acting like a big Jerkass to everyone you meet, for no good reason. And the rewards are usually worse than if you'd taken the 'good' path.
 * Mass Effect is a notable exception to the "evil or equivalent is always Chaotic Stupid" tendency in CRPGs. The evil-equivalent options (termed "Renegade") tend more towards I Did What I Had to Do or even Lawful Stupid. Even things as subtle as taking a more aggressive or reckless tack in conversations can earn you a few points for it. You do tend to have to kill more people on this route, but you tend to kill them because it's the most expedient route or "lawful" option, while the good-equivalent ("Paragon") emphasizes restraint, helping those in need, and finding a peaceful and equitable solution whenever possible.
 * Renegade Shepard does, however, engage in a great deal of Insane Troll Logic on occasion to justify racking up those renegade points. A low-score Renegade Shepard may be the best example, as not only will their overly aggressive dialogue fall flat on its face and fail to intimidate anyone, the only way to really get a low score in Paragon or Renegade is to alternate answers. It's no wonder they can't intimidate people: they probably just made some compassionate overtures, then said something bigoted, then over threats and then back to compassionate.
 * Neverwinter Nights (and its related expansions) works like this when it comes to the Good/Evil alignment axis. It's almost impossible to gain evil points unless you kill anyone who looks at you a little bit funny, regardless of the number of witnesses or your own personal credo. Meanwhile, performing any kind of altruistic act—even for nefarious or selfish purposes—will have you racking up the Good points.
 * Unfortunately, this is one of the major weaknesses of alignment in NWN, in that most characters end up as dog-kicking evil, or good. Almost no subtle, selfish evil, and it's very hard to maintain a neutral character over a long (series) of modules.
 * Neverwinter Nights 2 expansion Mask of the Betrayer introduced a mechanic of "soul consuming". Your character is given the option to suppress the urge (lawful & good points on alignment meter) or indulge in it (evil and chaotic points on alignment meter). These urges occur at regular intervals of real time. Indulging actually increases the rate of hunger generation; should you indulge, your hunger will grow enough to consume your own soul, ending the game permanently and requiring that you restart the entire game from the beginning or a far enough ago save where you can still salvage it via suppression. The consume path is thus nearly impossible to play to completion unless you do a speed run. This means almost everyone suppresses and are 100% Good/Lawful despite being utterly evil in their choices. A patch was released to resolve this situation by making suppression not affect your alignment.
 * The Mastermind of Mastermind World Conquest, whose goal is to destroy the Earth since he thinks it's the same thing as World Domination. He's also a big example of a Bad Boss, who takes more joy in executing Patsys than he should.
 * As mentioned above, RPG video games can push this to the point of ridiculousness. In the case of Knights of the Old Republic, it seems to be a case of Gameplay and Story Segregation: no sane light-siders like Carth or Bastila would stay with someone who kills every single NPC just because they can, but for the player, it's justified by their pursuit for Dark Side Points.
 * Knights of the Old Republic II presents much more variety in dark side options, such as convincing a mother to sell herself into slavery so she can be together with her daughter. In fact, the game recognizes two kinds of dark side acts: "cunning", which represent a Manipulative Bastard and which your teacher Kreia approves of, and "psychotic", which correspond to Chaotic Stupid and which Kreia scolds you for. There are other party members who do approve of psychotic acts, though, like the assassin droid HK-47.
 * On the other hand, there are moments when you are forced to learn how bad Lawful Stupid and Chaotic Stupid are by the mechanism of only giving you those options. No matter how subtle a villain you are, when a beggar asks if you have any spare change, your only options are giving him money or threatening to kill him. Which means it's lecture time from Kreia, and she won't be telling you to just keep walking and avoid eye contact.
 * In The Old Republic, Overseer Tremel will actually call you on this during one of the opening quests for the Sith Warrior if you decided to kill a spy that the Empire had taken prisoner instead of taking the light side points by sparing her life in return for her service to Imperial Intelligence. If you kill her, Tremel basically tells you to never waste someone who could be of use to you.
 * The Combine in Half Life 2 are the Lawful Evil version. They invade Earth for the sole purpose of consuming all its resources (including draining the oceans) and using humans as cannon fodder soldiers; while they're there, they implement a needlessly brutal totalitarian regime in which the "civil protection" forces have "beating quotas", and any captured "Anticitizens" are transformed into the horrific Stalkers.
 * The Ilwrath in Star Control 2 are the epitome of "TORTURE AND BLOOD AND DEATH, BAH HAH HAH" Stupid Evil. Turns out there's a reason for it, though --.
 * You can even momentarily confuse them in a conversation by pointing out that they self-identify as "evil", yet it is the preferred behaviour in their society, meaning that acting "evil" is actually a good thing in their value system, and therefore them calling it evil is a paradox.
 * While calling anyone is Touhou evil is inaccurate at best, there are still those that fall into a downplayed variant of this trope (Stupid Antagonism?), causing mayhem for petty reasons (if they have any at all) in spite of the miko with impervious Plot Armor that will not hesitate to beat the living crap out of them. The best example is Utsuho, who goes mad with power and has ambitions to Take Over the World almost immediately upon receiving her powers.
 * In Utsuho's defense, she was stupid before she was evil.
 * If you decide to venture down the path of Corruption in Dawn of War 2: Chaos Rising, you'll end up doing things this way most of the time. For example, the very first atrocity to commit is to blow up the city gates thus leaving it unprotected... OR you can walk ten meters aside and open the gates with a switch. Every time corruption points are awarded for lingering with a mission, rest assured that you will have to actually wait for the timer to expire twiddling your thumbs two steps away from the objective. Tainted wargear is just moderately better than the "clean" one so it'll be more like "damn, Cyrus' corruption level is low! Ok, what can I give him to fix things up?" And powers of Chaos, while great, have such long cooldowns it makes them essentially Too Awesome to Use, so they too will be mostly used for their corrupting potential.
 * Joe Barbaro from Mafia II, I guarantee it!!
 * There is a mission in City of Villains that invokes this trope. When checking on a Arachnos base, the agents you come across are spouting Stupid Evil lines. This is your first clue that something is wrong, as most Arachnos agents are Punch Clock Villains. Then, when you defeat one and it blows up, you figure out that they're Nemesis Automatons, which are known for being perfect replicas, until you look closely.
 * Colonel Volgin from Metal Gear Solid 3: Snake Eater is this trope incarnate. When he captures Big Boss, and "interrogates" him, he actually manages to reverse interrogate him, as Big Boss is too busy being beaten half to death to say anything, and Volgin is busy disclosing the location of . Later, when he and Snake are preparing to fight to the death, Snake asks what that is exactly, and Volgin tells him for no discernible reason.
 * Admiral De Loco from Skies of Arcadia. Unlike the Big Bad, he's not in it to make the world a better place, and unlike some of the other admirals he's not a Punch Clock Villain or in it for the fringe benefits. He just plain likes burning things and hurting people, and working for The Empire gives him plenty of opportunity. While he is clearly bugfuck insane and often lets his passion for pain and his vendetta against Vyse get in the way of making the right decisions, his position as the chief of Valua's research and development division is the only reason they don't just jettison him. And nobody gave a damn when his ship blew up in the Vortex after his last battle.
 * Shao Kahn in Mortal Kombat is obsessed with conquering other realms, and merging them into Outworld, so that (being the megalomaniac tyrant he is) he can not only cause devastation during his invasions, but exploit and oppress survivors for his own egotistical gain. He's treated as the personification of evil in the series. Problem is, as indicated in his ending in Armageddon, he conquers everything in the universe, destroying all lands AND seemingly all life too. And with nothing else left to conquer, he is left alone forever... to essentially go mad with boredom.
 * Moloch's ending somewhat counts as well. Yes he is a lumbering, towering, destructive demon from hell, but his non canonical ending in Armageddon reinforces that stereotype by telling that he would gain so much power and rage, becoming the ultimate destroyer, but in his stupidity and haste to unleash his power straight away, he destroys all portals to escape the realm he is in, and thus is unable to inflict his wrath upon other worlds.
 * In the Lost Chapters version of Fable, the evil option of the final choice is this. The options are either A. Throw an evil talking mask into the lava (Good) or B. put on the talking mask that tempts you with power and obviously just wants you to put it on so it can possess you (evil). Guess which option is the smart one and which is the really, really stupid one. Come on, guess.
 * The Umbrella Corporation in the Resident Evil series. This group of Mad Scientist-slash-Corrupt Corporate Executive types were obsessed with manipulating DNA and creating biological weapons (“BOWs”) in order to market them to various military firms, only to run into some problems. Problem #1: These BOWs are unpredictable, unstable, and usually destroy whatever facility they’re developed in. Problem #2: Said results of these BOWs are usually defeated and destroyed by one police officer. On top of that, they have a task force dedicated to cleaning up these accidents, but most of them are either eaten alive or infected. Problem #3, they never learn, never having any concern for repercussions of their experiments, even when the brunt of such repercussions come crashing down on their heads, and often come off as "evil for evil's sake". They'd nuke a school bus full of preschoolers if they thought it could be For Science, and that is clearly Not Hyperbole; they definitely would. Calling Umbrella “incompetent” would be an understatement. As noted above, the movie's incarnation stay true to this portrayal.
 * Union Aerospace Corporation, from the Doom franchise. Okay, the Earth is in the middle of an energy crisis, so the “geniuses” at this Mega Corp discover an energy source on Mars that originates from Hell itself. (That’s right, from Hell itself.) Not only that, they decide to explore Hell itself (which is infested with demons, of course) while mining its resources and looting its artifacts. On top  that, they knew one of their own scientists, Dr. Olivia Pierce, has started  a devil-worshiping cult among members of the organization, and do nothing. Worst of all, after the demons are unleashed and the heroic Space Marine saves humanity from being wiped out, their idiotic CEO Samuel Hayden doesn’t even thank him, and decides to continue research into the project. How dumb can you get?
 * Phenotrans, the Mega Corp main antagonists of the Dead Rising series. This is the group that markets a drug called Zombrex, a daily dose of which is required for anyone infected by a zombie, in order to stay human. And they charge an astronomical price for it. The apocalyptic ramifications of this deliberate price gouging - not to mention profiteering, as they deliberately try to worsen the Zombie Apocalypse - never occurs to them, nor do they ever realize that the overwhelming profits they're making are going to collapse once customers start to lose the funds to afford it. Not to mention they risk turning the entire world into a state where said profits will be worthless.
 * In the Hitman series, many of 47's targets - whether they be mobsters, dictators, terrorist leaders, or corrupt businessmen - have armed bodyguards protecting them, which will hamper your ability to eliminate the target, unless you find a way to convince them to dismiss these minions. There's always some way to do this, and it often seems remarkably easy to d so, often for some trivial reason. Even targets who are Properly Paranoid about someone trying to kill them can be convinced to take a risk that you can exploit.

Visual Novels

 * The original Student Council of Hope's Peak Academy from the Danganronpa series. The Academy had a reputation of being one of the best (and one of the most expensive) schools in the world, with students who graduated being renowned as experts in their fields. The Academy was originally rather picky about who was admitted until profits from tuition started to decline, so the Council decided to start a remedial program, the Reserve Course, that was just as expensive but lower quality. This eventually led to a caste-like social class system developing inside the school, which led to discrimination against the Reserve Course by both students and faculty - that discrimination soon gave way to violence, followed by actual murders and suicides, and eventually the first of the Killing Games, with its first victims being the Student Council themselves.

Web Comics
""I am compelled to do evil, regardless of its utility.""
 * In Looking for Group, Richard started out like this. In fact, he's still like this a lot. It helps that he's undead and a powerful sorcerer, not having to suffer any real consequences for his actions - although the other party members certainly did.
 * All his Stupid Evil acts DO have a point though.
 * In Dresden Codak, Dmitri's "Dungeons & Discourse" character is a Stupid Evil "Dark Kantian" as a parody of Kantian philosophy.


 * Belkar from The Order of the Stick is a great example because he's not just evil in a stupid way, he's evil because he's stupid. When Vaarsuvius cast a wisdom-boosting spell on him, he swore off evil and needless killing. Then V dismissed the spell and he ran off to kill things. However, he's recently had a vision/hallucination of Lord Shojo which has seemingly convinced him to avoid this; if he's a bit more selective with his carnage and act as if he's playing by everyone else's rules (in his words, "faking Character Development"), he can get people to stop hating him and possibly even get them to do what he wants.
 * Considering the setting (Dungeons and Dragons), Belkar is eerily effective at times compared to more intelligent and less stab-happy people. Belkar may also be smarter than he looks, as shown when he did a pretty effective job of dismantling Miko despite her ridiculous combat proficiency. He is defeated off-camera.
 * Of course, then he was just as stupid as you'd expect when the little hole in his resurrection plan is pointed out.
 * Subverted in the RPGamer comic Knights of the Dinner Table, where player Sara Felton becomes evil because of a cursed object, but acts, as she points out, definitely not Stupid. And she likes it.
 * Black Mage from 8-Bit Theater, who puts the "sociopath" back into Heroic Sociopath — and removes the "heroic" for good measure. His apparent solution to every problem is "kill everyone, starting with the people I hate", and it seems the only reason he hasn't put this plan into action is that he doesn't know where to start.
 * He also has a flowchart.
 * Kary is also this, considering she blows up her own minions just for fun and to prove that she is evil. Later, she blames the Light Warriors for killing her minions despite admitting that it was all her fault.
 * Minor villain Jaxon in Dominic Deegan is in the middle of a chaotic and extremely dangerous wilderness when he decides to stab his boss and go hunting for a monster that completely outclass him. Later, while wounded, he decides to attack the unscathed main character. He's either classic Stupid Evil or just suicidal.
 * Bangladesh Dupree of Girl Genius usually stays close to this but never all the way in (she survives, after all).
 * She has to be beaten unconscious so she stops trying to kill the guy trying to keep the airship they're on from being destroyed. Her attempts to follow orders inevitably add a lot of "kill people" between the lines. In all fairness to that first example, she was dazed, delirious and barely awake, and he had recently broken her jaw. And he did that because she attacked him when she saw him dragging her unconscious boss through the halls.
 * Bang also sees Klaus as some sort of a fatherly figure, so the first time she could as well be protective. In her case, it's sometimes hard to tell motivated violence from unmotivated. She's the girl who complains about orders to not burn any towns and then adds "even if a town really needed burning".
 * Regarding Bangladesh's tendency to add lots of 'kill people' to her orders, her intended purpose in the Baron's retinue is indiscriminate violence. When the Baron needs something done selectively, he uses someone else; DuPree and the Baron are both entirely aware that she was specifically hired to be a Person of Mass Destruction.
 * And remember that despite his motivations, functionally the Baron is a tyrant. He actually has a legitimate need for an indiscriminate terror weapon to threaten people with. The fact that DuPree both has a sincere affection and loyalty to her master and will reliably stop massacring people when given a stand-down order places her solidly in the top one percent of that particular category of Evil Overlord henchmen.
 * In Yet Another Fantasy Gamer Comic when princess Dewcup tried to join the Drow because Evil Is Cool, she got a thing or two mixed up.
 * Jack Noir (the alpha version, anyway) recently took a hard right into this trope via a Jail Break-like imprisonment sequence. He ends up beaten senseless by a gang of burly Prospitians.

Web Original

 * Sailor Nothing does a great Lampshade Hanging on Stupid Evil with the Yamiko, as lone-Punch Clock Villain-in-a-race-of-dog-raping-psychos General Cobalt
 * By one definition, "There is a fine line between Chaotic Evil and incompetent Lawful Evil."
 * In his regular editorial for the Role Playing Public Radio podcast, Tom Church explained that part of his hatred for the Star Wars RPG is the insistence of players on playing Sith while unable to grasp the concept of quiet, calculating menace that makes them such appealing villains in the first place. "Would you like to go out for some babies later this evening?" "Why yes, that would certainly hit the spot."

Western Animation
"Zim: I put the fires out! Tallest: You made them worse! Zim: Worse... Or better?"
 * In one episode of Samurai Jack, Aku promises a genius scientist to spare his village if he will make some super-robots to destroy the title character for him. The scientist does so. After they are done, Aku decides to "test them" by destroying the scientist's village for no reason whatsoever. This naturally leads to said scientist giving Jack the means to defeat these robots. Aku threw Villain Balls around a lot; there were many occasions he successfully caught Jack but ultimately came out short due to his sadistic tendencies, be it stalling his execution in favor of a Cool and Unusual Punishment or doublecrossing a Noble Demon that has the means to his escape for the sheer kick of it.
 * Another example: "Jack and the Warrior Woman". Yes, this is an episode where Aku wins, but dear lord did he take a lot of unnecessary risks in an endeavor simply because he wanted to gloat in Jack's face. He literally led Jack to a time portal (while disguised), just to destroy it and rub Jack's nose in it. Did he ever consider what would have happened had Jack caught on? In fact, episodes like "Jack and the Traveling Creatures" show that Jack learned from this mistake and was henceforth able to identify Aku more easily.
 * Which is Fridge Brilliance as Aku is constantly portrayed as the physical embodiment of evil. This means that his nature compels him to do Stupid Evil things, even though forgoing them temporarily would allow him to solve his problems faster. It's telling that Aku went for the direct killing blow exactly once,
 * Almost all the Captain Planet villains seem to have no other desire in life than to pollute the planet for the sake of polluting the planet. It's rare that the villain is actually trying to accomplish another goal with pollution being an unwanted (or even wanted) side effect.
 * Plunder, with his endangered animal hunting, seems to have basic greed as his ulterior motive as he seeks to cash in on his extreme poaching. This is the most sense that any villain makes on that show, and even then it's as one-dimensional as it gets, plus Plunder already has enough cash to finance any business he feels like - and yet he consistently chooses those that will lead to a superhero and his teenage hit squad wrecking everything for him, seemingly just so he can be an asshole to the environment.
 * Sly Sludge was just out for money. In one episode, he was almost a good guy, legitimately disposing of toxic waste for profit, although he didn't realize that his method, a shrink ray, would undo itself after a certain amount of time.
 * In Avatar: The Last Airbender, Admiral Zhao of the Fire Nation invades the capital of the Water Tribe; while there, it's revealed to him that there are spirits present that represent elements in nature and that harming them will have dire consequences for the world — not just the Water Tribe, the whole world (Fire Nation included). So what does he do? He decides to kill the Moon Spirit for no other reason than spite and pride. Gee Zhao, you think having the Moon might be a little important?.
 * In the Grand Finale of Transformers: Beast Wars, Megatron picks up the Villain Ball by . To add insult to injury.
 * Especially interesting is that Megatron was a Manipulative Bastard until the finale, when his god complex finally overwhelmed his intelligence.
 * Dr. Robotnik of Sonic Sat AM leaned into this in later episodes. The guy savored polluting the earth and was vehement on destroying all sentient life or robotocizing everyone into mindless slaves, leaving him the only free willed being on earth, bar his nephew and subordinate (who he was proved to find rather dispensable as well). He also fell into other cliched Villain Ball, capturing Sonic frequently and putting him in an easily escapable Cool and Unusual Punishment, and regularly abusing his potentially dangerously skilled minions (in the comic adaption, Snively did indeed alter Robotnik's devices to kill him as revenge).
 * Dick Dastardly of Wacky Races is on the low end of evil, always wanting to cheat to win, but despite pulling ahead with a huge lead numerous times, he finds himself stopping to try and sabotage the other racers. In the unaired pilot for Wacky Races Forever, Dick gets ahead, takes a nap, has a conversation with his boss, disobeys a direct order to win because he's got it in his head that this was a coded message telling him to do the opposite, and then drives toward the other racers to try and drive a giant cheese wedge into his opponents... despite being only a few feet from the finish line. Dastardly openly declares it's because he can't win fairly; he's a villain, and thus he has to cheat.
 * Though this was almost subverted in one episode where Dastardly, at the end of his rope, decides he's going to win fairly, and immediately blows past all the racers....only to stop to sign an autograph for Muttley, costing him the race.
 * There was another instance he almost won, but he just had to extend the nose of the Mean Machine to make sure he gets in first, resulting in him getting disqualified. Another time, he's one of the racers tied for the lead until he hears it will be a photo finish, causing him to immediately stop, get out of the car and pose.
 * Invader Zim veers between this and Chaotic Stupid:

"Dr. Polaris: Hey, aren't you going to wash your hands? Flash (in Luthor's body): No. Because I'm evil!"
 * Miraculous Ladybug Big Bad Hawk Moth edges into this from time to time, the biggest case probably being Mr. Pigeon. Poor Mr. Ramier has been akumatized 25 times (mostly offscreen) and each new time he's been beaten by the two heroes. Clearly he's a lonely and depressed man, making him a prime target for the akumas, but seriously, Hawk Moth would save a lot of time and energy if he just ignored the poor guy and looked elsewhere.
 * This gets even worse. By the time of the special - Miraculous World New York United Heroez - it's up to 51 times. Hawk Moth is just too dumb to give up on this guy.
 * Lampshaded in Justice League Unlimited: The Flash, stuck in the body of Lex Luthor (don't ask), has to keep up the charade of being Luthor in front of a gang of supervillains. The problem is, all-around-good-guy Flash has no idea how to act like a bad guy, much less one as suave as Luthor, which leads to this exchange as he's walking out of the bathroom:


 * Boris and Natasha (as in, Rocky and Bullwinkle's enemies, of course) have the reputation of incompetent crooks, but given where they came from, this is justified. Pottsylvania is a nation of war-mongers who have covertly declared war on everyone else, but never act on it because any other army could defeat them. In the past, they tried to get into weapons-dealing and designed the Assassin-8, a powerful heavy-duty military vehicle. Millions of them were produced before anyone took into account that Pottsylvania had only 12 miles of road, the ill-conceived project nearly destroying their economy. They have no resources, art, or other things to export, so their weak economy tends to be supported by Boris and Natasha's criminal schemes, which again, aren't very reliable.
 * In the DuckTales relaunch, the leaders of F.O.W.L. try very hard to avoid this, their preferred methods being global domination through subtlety and subterfuge. Unfortunately, they just can't seem to keep their agents from acting like open and blatant supervillains, which tends to cause their carefully-planned schemes to collapse into chaos. In fact, Bradford - the founder of the group - had simply wanted to call it O.W.L. (Organization for World Larceny) only adding the "F" - for "Fiendish" - in order to convince Black Heron to join them.
