Religion of Evil



Most often a Fantasy trope, the Religion of Evil has no pretenses of being anything other than... well, evil. Quite often it'll be a Card-Carrying Villain that refers to itself as evil; sometimes it won't say that word straight out, but its tenets and actions will be such that its followers are necessarily evil. Any time a temple's decoration involves lanterns made out of the skulls of their Human Sacrifices, it probably qualifies here (but see Sedlec Ossuary for a counter-example).

This religion has three common forms:
 * A small Secret Circle of Secrets (known more generally as a mystery cult or mystery religion).
 * The state religion of Mordor or The Empire.
 * The Evil Counterpart to a good religion, whose deity is not so much worshiped or prayed for rather than appeased and bribed towards leaving mortals alone.

In the latter cases, most of the time the masses will follow the religion out of fear rather than any genuine religious devotion. In the rarer cases when it exists openly in a "good" nation, it tends to be treated as a legitimate minority faith, perhaps worshiping the evil members of the pantheon. Members of the Deadly Decadent Court may attend, either in search of power or just for the thrill.

Because Religion Is Magic, devout practitioners and high ranking clergy will have powers, magic and other forms of The Dark Arts. You can expect the High Priest to emanate a Cross-Melting Aura.

This trope is the polar opposite of the Saintly Church. Also contrast with Path of Inspiration, where an evil religion masquerades as a more ordinary faith. Sometimes a Cult of Personality evolves (or is deliberately turned) into one of these. If a genuinely "good" religion is being twisted into evil, it's the Corrupt Church. Whatever the religion of evil worships will generally be the Bigger Bad, with demon lords, archdevils, Eldritch Abominations, gods of evil and Satan himself all being likely candidates.

Media portrayals of Satanism tend to fall directly into this trope; for this, see Hollywood Satanism.

Some people might consider one or more—if not all -- Real Life religions to be examples of this trope, but

Anime and Manga

 * Naruto has Hidan, a follower of Jashin ("evil god"). Aside from the lengthy praying and kickass immortality jutsu, he's required to kill his opponents via a blood-drinking, masochistic ritual. The religion first noticed him as a potential recruit when he murdered the people of his home village for no damn reason.
 * Higurashi no Naku Koro ni's "question arc" revolves around an "Oyashiro-sama" based religion. Partially averted when "Oyashiro" makes a proper appearance and
 * Dragon Ball GT has a religion that worships a giant gargoyle named Luud that turns people into dolls and absorbs their energy.
 * The Omekata cult from Mirai Nikki.
 * The Followers of Kira from Death Note. Ironically they will killed off by Kira (actually a follower of Kira but he would have done it himself if he wasn't being watched) as they were obviously creating the cult simply for prestige and greed.
 * After  they reemerge, praying for Kira's return. Possibly a subversion since we never see them do anything evil.
 * The Witch Cult from Re: Zero. A cult dedicated to the resurrection of the Witch of Envy, their members are an irredeemably evil cult of lunatics whose titles are derived from the Seven Deadly Sins. Simply being a member of this cult causes you to forfeit your rights to due process or any type of mercy; the Knights are under orders to kill members on sight.
 * The Society of Light in Yu-Gi-Oh! GX is never actually referred to as a cult, but it clearly is; its kind of obvious, given that the meetings they have are obviously sermons. And seeing as the Light of Ruin is ultimately behind it, clearly evil. The American dub version makes it even more obvious, surprisingly, giving the Society member making a sermon in one scene a voice with the accent of a stereotypical southern preacher.

Comic Books

 * The Church of Crime in The DCU.
 * At least they do it smart, with four branches that focus on four sins: the Deceit wing gets people to learn the religion by claiming that the whole thing is a hoax that they're seeking to expose, the Lust wing runs brothels and either slowly corrupts or outright blackmails repeat clients into Church membership, the Greed wing plays up just how much money there is to be made in crime, and the Murder wing... well, that's for people who already like killing. Hey, sometimes you gotta preach to the choir.
 * And Yea did the prophet Joker raise the holy crowbar to the heretic Robin's head. And he did anoint him and again until his brains could be seen. And There Was Much Rejoicing.
 * In the writers' notes for 52 (the series which introduced the Church of Crime), Mark Waid laments that they didn't pick a better name, noting that an evangelist saying, "Come and join the Church of Crime" probably won't get many converts.
 * Don't forget the Church of Blood! Even Nightwing was a member at one point!
 * All Hail Brother Blood!
 * The DCU loves this trope. There is also the Cult of Kobra, which controls a billion-dollar international crime syndicate and seeks to usher in the Kali Yuga (an "age of chaos") via terrorist attacks.
 * Speaking of Kali, Ravan, a member of the Jihad and later the Suicide Squad, is a member of an extremist Thugee cult with an opposite mission - to delay the coming of Kali Yuga - by killing. Every time he kills, Ravan says "Another thousand years, Kali..."
 * Which is, of course, a case of Western confusion. Historical Thuggee may or may not have worshiped Durga in her form as Kālī, but the Kali associated with the Kali Yuga is an entirely different figure—the names seem alike when transliterated. It works dramatically, anyway, so just go with it.
 * Another DCU example is the unnamed group of evil-worshipping monks that trained Prometheus and gave him the key to enter an alternate dimension.
 * And lets not forget Apokolips, where daily life for its billions of enslaved and brutalised denizens revolves around the endless, eternal worship of the resident despotic ruler and god-emperor of tyranny, the cruel and malevolent Darkseid.
 * The Church of Elvon in Nexus believes that all high technology increases energy consumption, and therefore increases entropy and accelerates the heat death of the universe. They therefore preach the overthrow of technological civilization by force. Violent, bloody, sadistic force. How this religion spread across the galaxy, well, hypocrisy is the tribute that virtue pays to vice?

Films -- Animation

 * The Uhluhtc worshippers in Heavy Metal.

Films -- Live-Action

 * The Kali worshippers in Indiana Jones and the Temple of Doom, very loosely based on the Real Life Thuggee cult. In truth, the Thugs were more like highway bandits, who strangled travelers with scarves in their sleep to rob them. While a cult did develop that gave religious motivations to their actions, it was not very widespread. Far from an evil cult goddess, Kali is the Goddess of eternal energy, the Punisher Of Evil, and is very popular in mainstream Hinduism.
 * It's treated more in the Expanded Universe materials than in the original films, but the Sith in Star Wars are a surprising aversion. The Sith do not see themselves as evil, but rather as embracing a proper, Social Darwinist philosophy of how society should be organized—an Ubermensch ideal, Klingon Promotion as a key tool to weed out the weak, etc. Combined with their view that the Force serves them, and not the other way around, this makes the Sith more of a Path of Inspiration for The Dark Side than a Religion of Evil.
 * An early script for Freddy vs. Jason featured a deranged cult that worshipped undead serial killer Freddy Krueger. They were called the "Fredheads".
 * Many early horror films employed Satanism as a religion of this type. The Black Cat (1934), The Seventh Victim (1943), and Rosemary's Baby (1968), The Omen (1976) are good examples.
 * The Seventh Victim is complicated; one of the heroes gives a Shut UP, Hannibal near the end where he accuses the Satanists of being Nietzsche wannabes. Also, the Satanists are mostly nonviolent and prefer to use social pressure to make people commit suicide rather than just killing them (one of them even comments on the contradiction inherent in their refusal to commit violence versus their need to kill all who betray them). But the leader does claim that he worships evil and refers to himself as "evil".
 * Both Psycho Cop and Shocker slasher films feature villains who fanatically worship Satan.
 * The Cult of Thorn from Halloween: The Curse of Michael Myers. Possibly.
 * The Deaders from Hellraiser Deader.
 * The villains in Wolfhound, the druids Zhadoba and Man-Eater, are said to be priests of the local Religion of Evil. They later turn against each other in an Enemy Civil War, until the protagonist kills Man-Eater in revenge for the destruction of his hometown, leaving Zhadoba the undisputed High Priest.
 * Waterworld features a Big Bad whose title is "Deacon of the Deep". His minions, known as Smokers to everyone else in Waterworld, are part of the Deacon's "Church of Eternal Growth", on a mission to conquer and consume all they survey.
 * Dagon (2001): In a small town called Imboca on the coast of Galicia in Spain,
 * The Japanese film Love Exposure has Zero Church.

Gamebooks

 * From the Lone Wolf series, the Acolytes of Vashna and the Cener Druids. The Acolytes wish to resurrect Vashna, the first and most powerful of the Darklords, so that he'd conquer the world with an army of undeads. The Druids plan to kill about every living being beside themselves with biological warfare. And the two are allies.
 * Hollywood Satanist cult members form the antagonists in the Fighting Fantasy book House of Hell

Literature
"The Druids of his own isle of Erin had strange dark rites of worship, but nothing like this. Dark trees shut in this grim scene, lit by a single torch. Through the branches moaned an eerie night-wind. Cormac was alone among men of a strange race and he had just seen the heart of a man ripped from his still pulsing body."
 * In Kushiel's Avatar by Jacqueline Carey, a Fantasy Counterpart Culture of Persia is tired of worshiping Ahura Mazda and getting nothing for it; a cult that worships his enemy, the evil Angra Mainyu kills the leaders of the country and takes over. It seems to pay off, as the members of this cult, who describe themselves as evil, actually do gain supernatural power, but it scares the hell out of everyone else, gods and humans alike.
 * The worship of Torak in the Belgariad, a prime example of the case where only the Grolims (priests) have any real faith and the masses follow out of fear. They keep the faith into the Malloreon, even though Torak is now dead. At the end, it's said that first act as a god will be turning the Grolims towards a less vicious path.
 * The Black Canons in Teresa Edgerton's Celydonn trilogy. They are noted for camouflaging themselves by taking on the external trappings of whatever religion is currently in power.
 * The Faith of the Pannion Seer in Steve Erickson's Malazan Book of the Fallen is a particularly nasty example, most evident in its conversion of the combat capable population into cannibal fanatic shock troops (through implied Mind Control) and the rest into their supplies.
 * The Sisters of the Dark in the Sword of Truth series have it as their stated goal to unleash the Keeper (read: Satan) on the world and end all life. (Except theirs; they believe that they will be granted immortality for doing so.)
 * Robin Jarvis has three of these in his two Deptford trilogies; the cults of Jupiter, Hobb (and his co-gods Mabb and Bauchan), and Suruth Scarophion. All of them practice sacrifice of their fellow sapient animals, since there are no human characters, in gruesome manners. Jupiter eats his sacrifices, Hobb's unfortunately named followers, the Hobbers skin their victims alive in a process referred to as the "bloodybones", and Scarophion's cult (known as the Scale) poison their victims with his blood, which dissolves the victim into a puddle of tar. You know, for kids.
 * Then in The Whitby Witches we get the Coven of the Black Sceptre, aka: the Brides of Crozier, a cult of crazy fangirl witches who can turn into dogs and worship the evil warlock Nathaniel Crozier who treats them like scum.
 * The child cult that worshipped "He Who Walks Behind The Rows" in the Stephen King short story Children of the Corn and the movie series.
 * A quintessential example is the Esoteric Order of Dagon from the H.P. Lovecraft story "Shadow over Innsmouth".
 * The religion Mijak religion in Karen Miller's Godspeaker Trilogy is an example of this, contrasting with the religion of Etherea. It's symbol was a scorpion which they bred in the temples to fill in a pool and swim in for divination. Animal blood was used a lot in ritual, drunk hot from the carcass and poured into pools to determine the will of god. Priests and the rulers of Mijak were chastised with beatings, including a young Zandakar. In fact.
 * Worship of Liart the Master of Torments, Achrya the Tangler of evil plots, Gitres the Un-maker, and Nayda the Un-namer in The Deed of Paksenarrion by Elizabeth Moon.
 * The Worshippers of Helgrind from Christopher Paolini's The Inheritance Cycle. They worship a mountain that they refer to as their "dread and terrible lord," kill slaves as sacrifices, drink human blood, and make offerings of their own flesh and limbs.
 * Both played straight and subverted in Mike Carey's post-The Sandman novels.
 * Played with in the Discworld. There are a few demon-worshipping cults, and Evil Harry Dread has occasionally run a temple of evil, but most people who've compared Discworld demons to Discworld gods have decided the main difference is PR. The worshippers of Bel-Shamharoth, the Soul Eater, on the other hand, are clearly insane. And mostly very, very dead.
 * It should be pointed out that there is a "Young Men's Reformed Cultists of the Ichor God Bel-Shamharoth Association", or "YMPA" in Ankh-Morpork...
 * S.M. Stirling provides several examples:
 * In the Nantucket novels, the sadistic Dr. Alice Hong starts a cult in Bronze-Age Achaea (Greece), with herself as the avatar of the Lady of Pain, to be worshipped by torture and sacrifice. This cult actually has official status within the Sacred Collegium, as Hong is the senior wife and lieutenant of William Walker, King of Men.
 * The Cult of Malik Nous, the Peacock Angel, in the alternate history novel The Peshawar Lancers. It is the prevalent religion in the remains of tsarist Russia following a meteor shower that destroys most of the northern hemisphere and involves the worship of the Slavic dark god Tchernabog, cannibalism and virgins who can tell the future (to make matters worse, their powers eventually drive them to insanity, at which point they are taken away to become breeders for the next generation).
 * The Church Universal and Triumphant (C.U.T.) in his Emberverse series.
 * The Yuuzhan Vong from the Star Wars Expanded Universe have an entire priesthood devoted to genocide, non-consensual bio-forming, and extreme masochism.
 * The Thebans in the Starfire books, who embark on a holy crusade to bring humans back into the light of worshipping Holy Terra. Never mind that they're aliens (explained later, trust me). There is seriously one Theban dude who does not like the prospect of the campaign.
 * In JRR Tolkien's The Lord of the Rings, the Dark Lord Sauron was worshipped as a god-king by the humans under his control. (The orcs, however, just saw him as their cruel slave-driver.) Aside from their leaders, though, they weren't themselves evil—they were forced to worship Sauron out of fear through lies and threats, not faith or devotion. This doesn't really come across in the movies.
 * Sauron also managed to convince Ar-Pharazôn and the Numenoreans to worship his master Morgoth/Melkor with Human Sacrifice, as part of the chain of events that lead to the downfall of Numenor described in Akallabeth.
 * The religion of the Pah-Wraiths in the Star Trek: Millennium series may qualify, as the "Ascendants"' principle aim was to destroy the universe for reasons of cosmic harmony. This may also be an example of Utopia Justifies the Means.
 * Friday the 13th: Church of the Divine Psychopath
 * The established church in Gene Wolfe's Book of the Long Sun is basically this, since the gods being worshipped, with one or two exceptions, are deranged sociopaths whose idea of a commandment is "Overthrow your government and let me know when it's done; if you sacrifice enough children you'll probably get my attention." Interestingly, though, the church itself is closer to a Saintly Church: individual clergy may be corrupt or unpleasant, but the church as a whole is a force for good, providing education and charity to the poor of the city.
 * The entire plot of each Odd Thomas book is the titular character pretty much foiling one of these. The first book? Satanists. The second? A crazy woman that has studied evil religions all over the world. The third? A guy that claims he can create life. The latest has apparently radical Islamics that planned to assassinate important government officials before blowing up several American cities with nukes.
 * David Weber's WarGod series has an entire pantheon of evil gods. The one who appears most often in the trilogy is Sharna, a scorpion-God of demons and assassins, although in the second and third books several more show up. Their worship is pretty classically evil, with rituals involving gang rape, mass torture, and cannibalism. Or worse.
 * About the best of the lot of them is Carnadosa, the Goddess of wizardry, who is more Chaotic Neutral than true evil. Her followers are generally depicted as smart and possessed of personal honor.
 * Strangely enough, although it's frequently emphasized in the text that no form of power is inherently evil and that it's only the methods that make dark wizardry evil, there seems to be no incentive for wizards to stay 'white,' since there are no 'good' institutions to counterbalance the Church of Carnadosa. The only representative of white wizardry is Wencit of Rum, and he seems to have no interest in taking apprentices or forming a new White Wizard academy (even though a similar institution exists for magi.) He's much too busy going around and executing wizards on the spot without any opportunity to reform. The practice of wizardry is also described as so seductive that those born with the talent cannot resist using it. And since it's illegal in every country in the world, you can't exactly join a support group for it. So essentially, if you are born with any kind of wizard power, you have no other options besides joining the Church of Carnadosa, practicing blood magic, and eventually getting killed by Wencit of Rum. Nice.
 * David Weber & John Ringo's Prince Roger series has the Fire Temples, in the volcanic land of Krath. Despite being a theocracy, none of the natives are willing to talk about their religion at all, and laws in the cities are quite prohibitive. They trade for slaves to act as "Servants of the God." There's a reason the local pirates fight to the last man to avoid capture.
 * Averted with Armagh's Satanists. They're the victors of a nasty schism on an all-Catholic planet, where they simply decided not to fight being called minions of Satan by a vicious inquisition. Their doctrine holds that God is being held prisoner by the angels, and the rebel armies of Satan will liberate him on judgement day. Other than the bizarre terminology in worshiping His Wickedness, they're basically good people.
 * The Maruli in The Stone Dance of the Chameleon bring human sacrifices to a god they call "The darkness under the trees". They appear to greatly fear him themselves and keep him imprisoned on the Island of Flies.
 * One of the most Badass Evil Church of Evils around would be the pantheon in Lord of Light, by Roger Zelazny. Not only did the evil gods have all the psionic superpowers of the Hindu gods, but if you wanted to be reincarnated in a younger body, then you had your mind scanned for disloyal thoughts: have some and BAMF! you're reborn in the body of a smelly ape.
 * In Robert E. Howard's Conan the Barbarian story "A Witch Shall Be Born", Salome institutes Human Sacrifice as part of the religious practices.
 * In both "The Phoenix on the Sword" and "The Scarlet Citadel", the worship of Set. Indeed, the first story has the only hint of White Magic and the intervention of good gods in Howard's stories.
 * The nation of Stygia is crawling (or slithering) with really nasty Set worshippers. Pythons are allowed to eat people in the streets as sacrifices.
 * In a move sure to annoy Real Life Hindus, Howard also depicts the religion of Hanuman as evil.
 * In the Kull story "The Shadow Kingdom", the priests of the Serpent. Then, they are half-human half-snake and do it to control people.
 * In Robert E. Howard's Kull/Bran Mak Morn story "Kings of the Night", Even Evil Has Standards is a comparison between two:


 * The worship of Lolth in War of the Spider Queen
 * The state religion/culture of Skrea in The Kingdoms Of Evil
 * Time Scout brings us Jack the Ripper and Aleister Crowley.
 * In Ape and Essence by Aldous Huxley, the post-apocalyptic Los Angeles is ruled by Belial worshipers. The devastation wrought by World War III made them lose belief in any deity but a malevolent one.
 * Played with in the Books of Swords: some of the gods, most notably Mars and Vulcan, are clearly malevolent, even evil. Interestingly, however, even though religion clearly exists in this world, we see very little organized religion. The only exceptions are the White Temple, which worships Ardneh, the Blue Temple, which ostensibly worships Tyche, and the Red Temple, which ostensibly worships Bacchus and Venus. Practically speaking, however, the White Temple is really a chain of hospitals, the Blue Temple is really just a bank, and the Red Temple is a chain of casinos and attached brothels. All three continue to function long after the gods they worship are dead. There is a reference in one book to a wizard bringing magical sacrifices or offerings to Mars to win his intercession in a battle, but that's about it for the explicit worship of any of the gods.
 * In the Empire of the East trilogy, however, it is made clear that Orcus, the demon prince, did compel his followers to worship him, so the titular empire was itself a Religion of Evil, at least until Orcus' top lieutenants overthrew him in a coup.

Live-Action TV

 * On True Blood, Maryann Forrester is a Maenad who mind-controls humans into worshiping Dionysus (Greek god of madness and ecstasy) through wild orgies and ritual sacrifice.
 * The Wraith worshippers in Stargate Atlantis are mostly in it for the benefits (not getting eaten).
 * Not quite. They're tortured until they believe that the Wraiths are gods.
 * They also addict their victims to Wraith enzyme.
 * Actually, it's not clear that all Wraith worshippers are tortured into it. Presumably, some people just believe it's "better to be the right hand of the devil than in his path" so join with the Wraith to avoid death and to reap the benefits of the enzyme, addicting though it may be.
 * The Shine Shine Dan from Warrior of Love Rainbowman are the KKK (against Japanese) with monsters and Faceless Mooks.
 * The Cult of the Pah-wraiths from Star Trek: Deep Space Nine.
 * The Harbingers who worship the First Evil in Buffy the Vampire Slayer, and pretty much every cult of the series. A list would cover at least an A4 page.
 * At least one Wolfram & Hart security guard/soldier told Angel that he believed, specifically, in the cause of evil, by name. did make others at least briefly re-evaluate their positions, however.
 * An episode of Criminal Minds featured a cannibalistic villain who worshipped Satan (or some kind of demonic entity). During the raid on his house, they find a hidden, demonic shrine, the walls of which were covered in Francisco Goya's Black Paintings and creepy symbols and Madness Mantras written in blood.
 * It's notable that the profilers state "He doesn't kill because he believes in Satan, he believes in Satan because he kills."
 * Lexx is built on this the first two seasons, with this "religion" being enforced on at least 20,000 worlds, in the goddamn Light Universe, even going to the almost absurd levels of the quote above, the only difference being that that is a parody, where this is a black comedy. Turns out And it worked.
 * Doctor Who features the Silence, whose belief that "silence will fall" when the oldest question in the universe is asked drive them to . Their most prominent adherents are members of a species of Grey/TheMenInBlack hybrids who make people forget all about them as soon as the people look away, and who have secretly controlled humans since humanity first existed.
 * The Daleks in the series 1 finale. The last Emperor Dalek to survive the Time War developed a massive god complex and rebuilt the Daleks as religious fanatics who worshiped him. "DO NOT BLASPHEME! DO NOT BLASPHEME!
 * The Disciples of Saxon in The End of Time worship The Master as a living god and ultimately bring about his resurrection.
 * In Robin of Sherwood there are three-and-a-half of these. First, Lilith and her unnamed companion who serve Simon de Belleme in the worship of Aziel (Simon's in it for the power, and his other servants are bewitched slaves, but Lilith seems to be a devotee). Second, the Lucifer-worshipping nuns in "The Swords of Wayland". The odd one out is "Cromm Cruac": the villagers indulge in human sacrifice, but they get an idyllic life in exchange - it's self-interest, not For the Evulz. Gulnar, that time round, gets involved for the sake of revenge - again, a normal human motive. But in Gulnar's next appearance, "The Time of the Wolf", he's running a murderous apocalyptic cult that really does seem to be just For the Evulz.
 * Subverted with the Cult of Baltar in Battlestar Galactica. They are perceived as a religion of evil by the fleet but are actually very peaceable.
 * Played straight with the Sons of Ares.
 * The Cylons themselves occasionally veer into this with their religious fanaticism.
 * Stargate SG-1 has the religion of Origin, which while not evil in an of itself, is run by Ancients that have managed to ascend. Its Priors also twist the meaning of the religion's holy book to justify mass murder and conquering other people whether they want to convert to Origin or not.

Tabletop Games

 * Most Dungeons & Dragons settings have one, if not dozens of these. Various "usually evil" creatures (drow, orcs, etc) commonly remain like this because most of their pantheons are evil and maintain vicious cycle.
 * Forgotten Realms got lots of these, but the most "notorious" were Bane (god of tyranny), then after he got killed, Cyric (strife), but he gone insane and was demoted, so Xvim son of Bane (hatred) carved up a territory for himself… and then Bane "got better", and all three ended up competing, as their worshippers are mostly the same sort of people. While Shar (goddess of darkness and loss) rarely attracts much attention, but remains among the most dangerous.
 * Most evil priesthoods are tolerated and respected, if not liked. As Ed Greenwood explains, most people simply aren't as powerful individuals as priests, and neither able nor willing to fight a whole church. Authorities who could tend to opt for peaceful coexistence with evil churches: any of them could be dangerous in hiding, but most won't act up when they have much to lose — they want to be legal and as such visible, since their job is to promote worship (if lip service) and influence of their gods. And they have their uses, after all. Of course, there are nasty exceptions.
 * Dragonlance has a few, but most remember only Takhisis.
 * Other major examples in the standard Third Edition D&D cosmology are the churches of Hextor, Nerull, Erythnul, Gruumsh, Maglubiyet, Tiamat, and any of the Demon Lords and Archdevils.
 * Hextor's church falls between this and Path of Inspiration. Where his clerics have power, they openly preach his creed of militarism, conquest and tyranny. In other places, they claim he's a god of fitness, discipline and strength.
 * Subverted in Eberron with the death/ancestor worship of the Aerenal Elves. Plenty of trappings that would be red flags in most settings (skull motifs, efforts of worshippers to look more dead, fallen troops remaining on duty) but they are as benevolent (if somewhat less universalist) as the Silver Flame (not counting the Knight Templars in the organization).
 * ... And then played straight with the Blood of Vol. Uncharacteristically, the setting information tries to be fair to those guys, despite their obvious black-hat practices like human sacrifice, necromancy, and immortality experiments. The cult's guiding moral philosophy is explained at great length and often from a sympathetic perspective; the faithful truly believe that this life is a torment and undeath is an acceptable escape. It's almost too bad the cult was founded by a diabolically evil lich who is using it for her own nefarious ends. Turns out she co-opted a pre-existing faith, and repackaged it into something more organized, and under her control.
 * The Dark Six are a classical pantheon of evil deities cast away from the main pantheon... and The Traveller. It's possibly subverted, as the Dark Six could be gods of nature that were removed from the Sovereign Host not because they were evil, but because the Sovereign Host was becoming the religion of civilization. Which, together with Eberron's Absent Deities-situation, leads to their evil possibly being a result of the Dark Six-worshippers gradually, over the ages, beginning to believe the propaganda spread about their deities.
 * A better example of being played straight is the typical Khyber Cult. They don't worship Khyber, just whatever they run across.
 * Evil faiths in Ravenloft tend more toward the Path of Inspiration model, but there are a number of minor cults dedicated to various Religions Of Evil imported from other gameworlds via the Mists. Of faiths native to the Land of Mists, that of the Wolf God (divine patron of werewolves) is the best example of an openly-bloodthirsty, destructive faith that looks to lay waste to civilization.
 * Planescape's Factions throw a wrench into this. There are quite a few of them who follow a belief system most of us wouldn't hesitate to describe as "evil" if we came across it in reality, but Planescape does its best to portray them from a detached, non-judgmental standpoint, often with inspiration from real life. The ridiculously callous and selfish Fated justify themselves based on, essentially, the writings of Nietzsche and Ayn Rand. The Dustmen, who have all of the trappings of a Religion of Evil (decorating things with skulls and wearing black robes and using zombies and such) have a belief system that is basically Buddhism with the added twist that they believe they've already lived their life and are now trapped in an existence of rebirth into a state of "False Death" until their souls learn to let go of suffering and attachment. The Doomguard has a philosophy centered around the inevitability of entropy, which can range from Omnicidal Maniac behavior to a simple acceptance that nothing can be accomplished without destroying something else.
 * Interestingly enough, in the default D&D cosmology evil people generally still go to the so-called Lower Planes (assorted hellish afterlife dimensions, although only one group is considered "Hell" proper) after death to be tortured by the local denizens. If one is sharp and tough, however, he/she can survive and even become more powerful. Most denizens of the Lower Planes don't envision themselves in any other place—with the notable exception of the prison plane of Carceri, where no-one wants to end up, and everyone who's already there wants out.
 * Fiendish Codex II notes that most evil people are egotistical—they don't look at lemures or dretches (bottom-of-the-barrel devils and demons, respectively) and think that will be their afterlife. They think they'll shoot to the top of the infernal hierarchies immediately. In addition, resurrection magic doesn't generally leave the revived with memories of where their soul ended up, so nobody has firsthand information as to what happens after you get killed.
 * Both subverted and played straight in the new fourth edition of D&D. Some evil gods actually have large (rational) followings that aren't typically seen as "evil". For example, non-evil worshippers of Bane (god of tyranny) might see him as the patron of "rightful and strong authority", and Grummsh (god of savagery) is worshipped by many as the "god of strength and conquest". A new deity, the Raven Queen, is worshipped as a personification of Death without the evil overtones (and is basically a mixture of Wee Jas and Morr from Warhammer Fantasy Battle). On the other hand, for those who like this trope straight, we still have Lolth, Vecna, Torog, etc., and also a lot of classic Demon Princes who are worshipped as gods by deranged cultists. And even then, some of the more "evil" gods can be justified: for example, Torog's domains include jailers and torturers—necessary? Perhaps. Likeable? No, not at all.
 * The Raven Queen also has a good bit of My Species Doth Protest Too Much, as plenty of her worshippers are a bit overenthusiastic. (Shadar-kai especially tend to end up as random encounters.)
 * The one that takes the cake is probably Tharizdun, the god of Omnicidal Maniac who has been imprisoned since the dawn of time by all the other deities (good, neutral, and evil) working together. He still has worshipers.
 * Pathfinder has a number of these. The Church of Asmodeus controls Cheliax, while their neighbour, Nidal, worships Zon-Kuthon. Cultists of Norgorber, Urgathoa, Lamashtu, and even Rovagug are distressingly common, both among society's outcasts, and the setting's various monsters. And that's without getting into the cults centred on various Demon Lords, Archdevils, evil demigods, or god forbid, The Four Horsemen. The Demon Lord Angazahn in particular has a substantial following in the Mwangi Expanse.
 * In the New World of Darkness game Vampire: The Requiem there's Belial's Brood, a covenant of vampires that are debauched and cruel even by vampire standards. And this is a Darker and Edgier Sick Sad World where being a Friendly Neighborhood Vampire is a pipe dream. So trust me: "Debauched and cruel by vampire standards" means they aren't so much at the bottom of the barrel as outside of it holding up a liquor store. Their cults believe that the inner "Beast" that all vampires struggle with is actually a fragment of divinity caged by imperfect humanity; so, in an effort to "liberate" and master the Beast, they deliberately lead their followers in acts that drive the Karma Meter down faster than mercury in Antarctica.
 * The Brood are a Religion of Eviler to other vampires, while the Lancea Sanctum have set themselves up as a Religion of Evil to humanity, as they act as a dark mirror of Christianity (and other mortal faiths to an extent). Their message is "don't sin against God, or you will be cursed like us."
 * The Old World of Darkness has a few of these as well, most notably the Black Spiral Dancers (werewolves who worship the Wyrm, the spirit of decay and destruction), and Vampires who follow the Path of Typhon, and a couple other Paths of Enlightenment that are For the Evulz. There are many other splats that deal with demon worship, but those are more along the lines of quid pro quo than true devotion.
 * And then there's the Sabbat, who could be considered the predecessors of both the Lancea Sanctum and Belial's Brood. Many of them worship Caine, the first vampire, and believe that during Gehenna, he will rise up and save his childer from the antediluvians that means to devour them. Their membership consists of the most amoral vampires (and that's saying something), who often have to pick up alternate Paths of Enlightenment to avoid falling to their Beasts and practice twisted rituals that often involve human sacrifice. And the real kicker? They fucking hate infernalists.
 * Enter worship of any of the Gods of Chaos in Warhammer Fantasy Battle and Warhammer 40,000 and you hit Religion of Evil levels very quickly. Each Chaos God has their own angle: Slaanesh worshippers pursue emotional excesses, Khorne worshippers seek only to spill blood in Khorne's name, Nurgle worshippers spread disease and despair, and Tzeentch worshippers are fuelled by ambition and seek to evolve and change. The downside is that there is a roughly 99% chance of getting possessed, sacrificed, burned by witch-hunters or simply turning into a screeching, frothing, mindless mutant abomination with four heads that vomit blue fire. Absolute power corrupts absolutely, but only Chaos gives you eyes inside your mouth.
 * There's also the other side of that coin; the Gods of Chaos are the gods of bloodshed, disease, sexual perversion, and mutation. They're also the gods of Honor, Fortitude, Love, and Hope. Oh, you bet it's a Crapsack World.
 * That said, as mentioned by Ciaphas Cain (in Sandy Mitchell's The Traitor's Hand), many Chaos cultists start out presuming the organizations they're joining are relatively innocuous like crime networks, interesting occult or deviant pleasure groups, or even social reform movements; they often only grasp the true nature of what they've joined when they're far too corrupted to even care anymore. The cult in that book mostly consisted of the bored, and very few of them had any idea what they were getting themselves into.
 * At least in Warhammer Fantasy Battle, many of the cults initially present themselves as organizations for social and political change, something that the Empire could rather use.
 * It should be noted that Chaos Cultists tend to view the mutations and horrible deformities as blessings. Not to mention that there does exist for every follower of chaos a very small chance of getting immortality by basically being promoted to a demonic demi-god. Of course, most of them die or go totally insane way before ever getting close, but as with the D&D example above, most don't look at the likelihood of death or spawnhood and think "hey, that could be me"; they're convinced that they will be among those lucky enough to ascend to daemonhood.
 * The Word Bearers legion take this trope to its logical conclusion.In fact, Lorgar devoting himself to his official Religion of Evil is pretty much responsible for the 40kverse being the Crapsack Universe it currently is; it was Lorgar's minions who secretly manipulated events so that the Horus Heresy was inevitable—it was even a Word Bearer Chaplain who conducted the Chaos ritual that ultimately saw Horus corrupted and sworn to Chaos.
 * The best part? The other religions aren't that much better. At least Chaos is sort of honest about what it does, and doesn't pretend to be good.
 * In fact, the Imperial Cult worshipped by the Imperium? Created by Lorgar, primarch of the Word Bearers, as his first try at organized religion; when the Emperor smacked him upside the head with the fact he did not want any religions in his Imperium, even—or especially—if those religions deified him as a God-Emperor, Lorgar went running into the arms of the Chaos Gods.
 * The most interesting legacy of Lorgar may be the Chaplains, the unique sect of Warrior Priests amongst the Space Marines. Their official purpose is to help keep Space Marines from being corrupted; however, not only were they created by the very first Legion to be corrupted (none of the other Traitor Legions have fallen Chaplains amongst their ranks because Chaplains were strictly found amongst the religiously-zealous Word Bearers), they were actually instrumental in corrupting the other Traitor Legions. Of course, nobody remembers this fact now...
 * Let's not forget about the Genestealer cults. Worshippers of a Horde of Alien Locusts, whose membership is made up exclusively of the victims of Face Full of Alien Wingwong and their Half-Human Hybrid children. They exist to increase their membership until they register in the Hive Caste System, at which point the bugs turn up and devour everything on the planet, including the cult.
 * A small cult in the setting of the REIGN RPG believes in heaven for the good, hell for the evil and reincarnation for everyone else. They also believe that if you are killed by the archery-based martial arts style they invented, you get "promoted" in the afterlife. Thus, if you kill an evil person, they come back and get another chance, while killing anyone else gets them into heaven before they can do anything bad! They killed a lot of people.
 * In Magic: The Gathering, until its destruction Phyrexia (think equal parts Cybernetics Eat Your Soul, Body Horror, and The Legions of Hell) always had religious traits, with Yawgmoth at the head. These traits have been exaggerated by the white-mana faction of the reborn Phyrexia, calling itself the Machine Orthodoxy. In keeping with its Phyrexian nature, it really isn't very pleasant; the flaying and horrible mutilation of enemies and converts, gratuitous use of ritualised surgery, and stripping angels of their honour and turning them into sociopathic monsters all get four thumbs up from the average Whiterexian. For added horror, white has Phyrexian Unlife, which depicts an androgynous but most likely female porcelain mask looking at her newly-compleated hands. And who do you do this to when you cast it? A creature? No. Your opponent? No. You do it to yourself.
 * Such cults fit in well in the world where Kult is set in.
 * Exalted features cults worshipping the Yozis, the titanic Demon Princes who created the world but were overthrown by the gods. Yozis are insane and evil, horribly twisted by their rage against the gods, and they want to corrupt Creation into a horribly painful hellhole. If they ever escaped their prison-world and remade the world the way they now want, it would be a Fate Worse Than Death for pretty much all humanity. Indeed, before they were overthrown, humans were one of the most miserable species in existence. Nonetheless, some humans worship them and work to free them.

Video Games

 * The worshippers of whatever ancient deity you pick in Eternal Darkness.
 * Except possibly Mantorok, who seems to have posed as a relatively benevolent god for the locals.
 * The Cult of the Damned in Warcraft. Originally they were often seduced by promises of eternal life, social grievances, and disillusionment with the Holy Light. In the modern era this is exacerbated by the widespread trauma and suffering experienced by humanity. Members are given a potion after their initiation that removes their ability to object and makes them unquestioning fanatics.
 * And the followers of the demons of the Burning Legion from the same series.
 * Also the Twilight Hammer, who worship the cosmic horroresque Old Gods. The entire goal of their religion is to bring about the end of the world.
 * The Nihilist Church in Lusternia. They worship five extraplanar entities that are essentially Anthropomorphic Personification posterboys of madness, pain, rage, forbidden knowledge and pride. They serve as spiritual leaders for the Tainted city of Magnagora, and are keen practitioners of Necromancy.
 * Final Fantasy VI: Okay, sure, the Cult of Kefka is composed of people who have had their homes and possessions reduced to dust, friends and families slaughtered judged and world ruined by Kefka, and worshipping him is pretty much the only way you're allowed to keep your miserable life, so they're more The Church of Woobies than anything else, but really now; worshipping him (and being willing to go as far as to fight for him in order to escape his judgement) really isn't going to make it better.
 * The Lopto Sect of Fire Emblem Jugdral is a cult devoted to the dark dragon Loptous (A alternate spelling of Loki, Norse God of Evil), and a once-former Empire founded by a ex-Bishop named Galle who became disenchanted with the divine dragons and made a deal with Loptuous for power to conquer. They are rather keen on miss kidnapping of children to be used as human sacrifices to Loptous,and the tome that bears his name and was the source of Galle's power possesses the Final Boss, Prince Yurius, designed to be the dragon's vessel on Earth. All-in-all, a rather unpleaseant group.
 * In Mass Effect, the Geth religion basically comes down to the total extinction of all organic life in the galaxy. Unfortunately, the gods they worship—the Reapers—are quite real...
 * And in an expansion of the trope
 * The second game reveals that the vast majority of the Geth prefer a "live and let live" approach, the ones that followed Saren being seen as heretics.
 * An indoctrinated Hanar combines this with Insane Troll Logic to come to the conclusion that since Hanar worship Protheans, and Protheans were turned into Collectors who now serve the Reapers, Hanar must worship the Reapers and aid them in their goal of total destruction.
 * "Los Illuminados" from Resident Evil 4 have a massive army of Black Cloak monks, cannibalism, institutionalized child murder, and colossal Body Horror.
 * In The Elder Scrolls IV: Oblivion, there's the Mythic Dawn, a cult lead by the Big Bad, who, among other things, require you to offer 'red drink' to Mehrunes Dagon (the god they worship) in order to join. There's also the Dark Brotherhood, who are a combination of a Religion of Evil, a Murder, Inc., and Knight Templars.
 * Also, in The Elder Scrolls III: Morrowind, there is the Dagoth Ur cult whose followers first start seeing things and then turn into semi-sentient monstrosities who can only do their master's bidding and are to be killed on sight.
 * Most Daedric cults on the other hand are pretty friendly and just want to worship their kinda evil god in peace
 * In Romancing SaGa the three Dark Gods each have followers, however the religion supporting the Big Bad is the Religion of Evil
 * The Chzo Mythos series of games concerns . The cult has prayer books, religious texts, a symbol, a founder, and a fairly clear objective. Chzo is referred to as a "pain elemental", and appropriately, all of the order are masochists.
 * You might also call them a "religion of idiots", because they hadn't got a clue that their objective was completely wrong. They were also being fooled by their "god".
 * At first glance, the Order of the Harvest Moon from the adventure game Harvester seems like a slightly skewed Brotherhood of Funny Hats. Of course, once you've passed the final step of their initiation ritual, which involves navigating an Evil Tower of Ominousness, killing horrible monsters, and having sinister and nihilistic conversations with really nasty people, you've discovered their true colors... and their true intentions.
 * Lampshade Hanging in Star Control II: the Ilwrath are theocratic self-declared worshippers of Evil and Death, but if the player confronts them over this ("If your actions are judged by your society as correct, aren't you, in fact, good?") they tie themselves into a logical knot before deciding to attack the player for being annoying.
 * A bit of a subversion in Dead Space, as the Church of Unitology seems like this as you go through the game, what with them wanting bring the Marker back to Earth and turn everyone into Necromorphs, but you'll find somewhere in the middle of play that there are Unitologists that didn't think turning into Necromorphs was all that of a great idea, but Mercer killed them. Played straight in that this really seems to be how the Church and most Unitologists are.
 * The promise of a coming of angels that will touch the bodies of the dead to transform them into heavenly beings that are reborn in paradise doesn't sound so bad by itself. It's only when you realize that these "angels are giant alien bats that will jam an arm-long spine into your skull and transform you into space zombies, which neither bother to make a difference between belivers and non-believers, wait for your natural death, or make your death any less painfull than being torn to pieces, that one starts to doubt that path to paradise is really such a good idea.
 * What really makes it ironic though, is that its "prophet" didn't start it, and in fact was opposed to it. He merely found the Black Marker and was immune to its effects, and people that were effected by it started worshiping him as a prophet. He began trying to blow the whistle on a government plot to use the Marker as a weapon. The two military officials that were in charge of the project kidnapped him and killed him with a Necromorph to martyr him in order to strengthen Unitology, which would most likely throw suspicion away from the government and quell social upheaval that Altman was causing.
 * The Nhuvisarum in the Summoner games. They enslave entire nations and purposely garner a 0% Approval Rating because their magical powers are literally fueled by human suffering.
 * Pretty much every dungeon in Exile/Avernum will have an evil temple with skulls, bloodstains, and/or traps that unleash demons in it somewhere.
 * Played straight and parodied in the Fable games with the Chapel of Skorm and the Temple of Shadows. The latter example involves a rather amusing parody. "On Wednesdays we drain the blood of virgin chickens. On Thursdays we annoint ourselves with said blood. Friday is poker night, of course"; and "If there's one downside to being an evil cultist, it's that we must take our tea without milk" indeed.
 * Dragon Quest V features the Order of Zugzwang, a cult that worships the Big Bad. Interestingly, it counts both monsters and humans amongst its ranks.
 * The Multitude in the Roguelike Incursion is a, well, multitude of demon ghosts who each want you to go kill and slaughter and rape and be generally depraved in that particular ghost's name, and are willing to bribe you with power for it. Zurvash is slightly more philosophical about it, making no bones about the fact that he has no regard for civilization, ethics, or foresight, and glorying in brutality and domination.
 * EVE Online: The Blood Raiders. Since their "religion" invovles vivisection with no anesthesia.... And to a lesser extent Sansa's Nation. They believe in turning people in to "true humans" by destroying the personality yet keeping intelligence and creativity intact.
 * The Order of the One True Way in Suikoden Tierkreis has elements those can qualify as Nightmare Fuels. For example, early in the game,.
 * The Thurists are very much this. Every member indulges in an Evil Laugh, even in the battle quips (ordinary units will have the laugh replace their normal grunts and cries), their "god" is World Eater Thuris, the sickest of the lot (mentally, that is - Raksha's a Magnificent Bastard and Feinne is simply mindless), and they regularly purge other religions, especially the followers of Apis, who many of their members were converted from. And if that wasn't bad enough, they have a reputation for indulging in the spread of Scarlet Iago - this may have killed  Trish's parents 15 years ago during a vaccine panic, and if it weren't for a charitable donation by Cristophe and Levin, it could have claimed the Raide survivors under Nereid care as well. Of course, Kanan and her lot all fail to comprehend why evil religions are doomed to swift destruction - namely, that they are mere pawns for the "gods" they worship.
 * Church of the Key in Alundra 2. They promise you happiness, they turn you into a soulless slave.
 * Legacy of Kain has a few examples, but only one truly fits. While the ancient vampires worshipped the soul devouring Elder God, they believed his wheel of fate was good and divine. The vampire's of Kain's empire deified him after they conquered humanity, he was their creator. The priests of Avernus Cathedral(the offical religion of which is never explored in detail), however, are members of a secret cult worshipping Hash'ak'gik, a group of hylden possessing the body of a horribly mutated vampire from the future. They preformed ritual human sacrifice to their 'god', cutting the throats of their first born and throwing them into a massive pit.
 * In Rise of the Kasai the titular Kasai is an evil cult who's only purpose is to gather up six marks that are branded on to people's flesh, and use them to cast a spell that will allow their God of Evil to enter the world and wreak havok. Said marks are often found on children, who they will kill and skin to use the magic.
 * Linley's Dungeon Crawl features several Religions of Evil, from Beogh, god of the orcs, Kikubaaqudgha, an evil demon-god of necromantic magic, Makhleb, god of chaos and violence, to Yredelemnul, an evil god of death. Xom, god of true chaos, is an interesting case, in that he isn't looking for followers quite so much as new playthings.
 * In Metroid Prime 3, the corrupted Space Pirates certainly seem to regard Dark Samus like Jesus, referring to themselves as disciples.
 * The Order of the Silent Hill series worship a God that has promised to bring about the salvation of humanity and paradise on Earth. Given that their plans for helping God bring this about invariably involve physical and psychological torture and murder (especially of children and childhood best friends) and that all of the Order members (with the possible exception of Claudia, who can be seen as just a Well-Intentioned Extremist) encountered in the series are amoral, vicious sadists, and/or outright insane, one can be forgiven for wondering what exactly their paradise would entail. It's telling that the main antagonist of Silent Hill 3, the Order priestess Claudia Wolf, who orchestrates a brutal murder and has the protagonist quite literally put through Hell, would apparently be considered one of the Order's more liberal theologians.
 * Something else that makes the Order look like pure evil rather than just a Scary Amoral Religion is that their God literally thrives on suffering and hatred, although Claudia reasons that a truly compassionate God must first experience the horrors of the world through a human host.
 * Valkyria Chronicles has Yggdism, a cult that worships the setting's resident omnicidal Eldritch Abominations as gods and preaches that brutal oppression and mass slaughter of Darcsens should be a way of life. While not all that prevalent in the original, one of the main villains from the sequel is a devout follower of Yggdism.
 * Halo has an interesting example. While the religion of the Covenant didn't start out this way, thanks to the Prophets misinterpreting the sayings of the Oracle in their holy city and , it soon turns the Covenant into an alliance of omnicidal maniacs. Granted, they didn't think they were going to be killed as well.
 * In Mortal Kombat, the Brotherhood of Shadow follows the fallen Elder God Shinnok.
 * The White Mantle of Guild Wars: Prophecies starts out seeming like a bunch of pretty cool guys. They're a functional theocracy, wear nice outfits, welcome you into Kryta after your homeland gets burnt to a crisp, and even induct you into their order. The only real problem is that the gods they worship are actually a race of amoral illusion-weavers who are currently harvesting the souls of specific individuals to power the seal on an entrance to the realm of a very real and very evil god. And they're not doing this because it's necessary for the greater good; they just want to make sure they themselves stay alive.
 * After the destruction of most of the Mursaat race by the opening of the entrance they'd kept sealed until some nosy heroes showed up, the White Mantle hired former bandits, thugs, and other detritus of society, named them Peacekeepers, and sent them out to kill anyone who didn't agree with the Mantle.
 * Hinted at with the Scary Dogmatic Aliens in Duke Nukem II: "We'd kill you, you see, but our religion prevents the interruption of suffering."
 * The Civilization 4 Mod Fall From Heaven includes the Ashen Veil religion, which explicitly seeks to bring hell itself to Erebus.
 * The Legend of Zelda occasionally portrays Ganon as being worshiped as a god, with his more devout followers trying to revive him or selling their souls to him for power. Of course, the Triforce of Power, the source of his magic, is a third of the most powerful holy artifact in the series, so he does have deity-like powers.
 * The Path of Dark in the old Might and Magic verse is heavily implied to be either this or a Philosophy of Evil - it has adherents that self-identify as Villains, some members of it call you a do-gooder, or criticise your lack of cruelty if you happen to align with the Path of Light...
 * In addition to various examples from the usual suspects among the Forgotten Realms gods, Neverwinter Nights 2 has people who worship the King of Shadows (the Pure Magic Being Big Bad). The second expansion adds the cult of Zehir, worshipers of the yuan-ti god of poison who have set themselves up as the rival to a different Religion of Evil, those who worship Sseth, the yuan-ti's normal patron deity.
 * Runescape originally had only three gods, Saradomin, Zamorak, and Guthix, who were basically good, evil, and balance. Zamorak is considered more chaotic now, and has some followers who are decent and suggest that their reputation is Written by the Winners. Still, the Zamorakians are arguably 99% evil, featuring all sorts of bloody murder, their members include vampires, werewolves, demons, and an Evil Chicken, and many of their rituals actually use the word evil.

Web Comics
""Now each of you prove yourselves! Come to the centre of the arena and curse God's name! Denounce His only son! For only those with the courage to face God's wrath are worthy to bask in His glory!" They don't even think twice. No wonder they're damned."
 * MAG-ISA—In this comic, the cult known as The Order is the religion of evil.
 * The Dimension of Pain demons in Sluggy Freelance worship the Demon King, who thinks the highest compliment he can give something is "How evil".
 * The same goes for the cult of K'Z'K started up by Chilus.
 * The doom cultists in 8-Bit Theater.
 * And whatever Black Mage is worshipping that week. Though Black Mage admits he's only worshipping them for the express purpose of gaining their dark blessings until he is powerful enough to usurp them for his own ends.
 * This comes back to bite him later on, when Chaos rises and he tries to get on his team. Chaos then tells him that he's planning on destroying everything, Black Mage asks if that includes him. Chaos's response? "Biiiiiiiiiiiig time". Needless to say, Black Mage immediately sees the need to kill Chaos.
 * Vince's cult in Jack is a weird example in that the cultists are all already in Hell, and are turning to the cult to try and get them out. Vince has a lot of fun manipulating them.


 * At which point  This only makes them even more dedicated to him.
 * Subverted in The Order of the Stick: Despite the deity being called "The Dark One" and despite his worshipers being almost universally evil creatures, it's not quite a Religion of Evil but rather a religion of people who are so downtrodden that they're willing to do just about anything to even slightly improve their lot in life, even to the point of tempting The End of the World as We Know It. More a religion of evil people than a Religion of Evil.

Web Original

 * Subverted in the Whateley Universe with the Cult of Kellith, worshiping the daughter of Gothmog (and granddaughter of Shub-Niggurath)... who, for all that she's ostensibly a lust demoness, started out as a human, is currently attending Whateley Academy as a student, and is generally not a bad person. (Although there are signs that she's starting to actively distance herself from her previous human existence and morals, so this may change in the future—she is a Cosmic Horror in the making, after all.) Played straight, however, with the Tong of the Black Madonna, an apparent mystical cult opposing the Tao and making trouble for its current Handmaid a.k.a. Bladedancer, including a concerted attempt to attack her in her dreams via a spell powered by human mass sacrifice.
 * The Cult of Kellith probably isn't a subversion, but a real example. The head of the cult was actively trying to turn Carmilla evil . Cultists have been seen to do things like sacrifice cute animals in her name. And there may be a hundred thousand of them out there doing god only knows what.

Western Animation

 * The villagers from Season of the Skull in Super Robot Monkey Team Hyperforce Go! worship the Skeleton King.
 * Ezekiel Rage from The Real Adventures of Jonny Quest had the Book of Rage, a supposed bible from which all apocalyptic prophecies must come to pass, and which he worships fervently. Subverted in the fact that the book was actually empty, save for a picture of his dead family.
 * A kind of meta-example, but on The Fairly OddParents, there was shown to be a church on Yugopotamia, complete with a priest for Mark and Mandie's wedding. Nothing is said about it, but considering the nature of the Yugopotamians, Fridge Logic gets you to realize this trope is likely in play.
