If You're So Evil Eat This Kitten



"The Forehead: Wait a minute... Something smells fishy here. I don't think you guys are villains! The Tick: Oh no, we're- We're bad! Arthur: Yeah, the worst! The Forehead: Okay, if you guys are so evil, why don't you just... Eat this kitten!"

- The Tick (animation), "Armless But Not Harmless"

The Bad Guys challenge someone (usually the hero pretending to be a Bad Guy) to do something evil to prove his evilness. While the trope name suggests cartoonish super-villainy this can equally apply to more serious stories, where this trope could be named If You're So Evil Shoot This Cop. Basically, any test to demonstrate the willingness of a person to do immoral deeds, either to demonstrate the individual isn't the hero in disguise, or to just prove that the character isn't going to be afraid of dirty work.

Sometimes it's inverted for comic effect, where the person being challenged is genuinely evil and does the evil deed without hesitation. Sometimes the inversion is even exaggerated, where the person not only does the evil deed, but even does it in such a way to make the challengers themselves wince.

Sometimes it's played straight for maximum angst, when the evil deed means hurting or killing another good character.

In almost all circumstances, the hero either Takes A Third Option or fails this particular test.

In anime and manga this is frequently called a fumi-e from the analogy with the historical practice of making people step on Christian religious symbols to prove they were not Christians.

Shoot Your Mate is a subtrope. Related to Deadly Graduation, where the victorious 'kitten' is the one who eats the rest of the litter. Contrast Secret Test of Character, God Test, and Even Evil Has Standards.

Anime and Manga

 * Code Geass had "If you're so evil, shoot this Britannian!" and "If you're so evil, murder the innocents!" as tests for Suzaku. Not to mention "If you're so evil, execute your childhood mentor!"
 * In the Unknow Zanpakutou Tales arc of Bleach, Senbonzakura is distrustful of Byakuya joining the zanpakutou side of the war, so he makes him a challenge to prove his loyalty. That challenge is .

 * Also used in Dangaioh, when  defies Pai Thunder   to kill   in front of him.
 * Early in Kurau Phantom Memory, Kurau is asked to shoot her (incognito) friend to prove she's not with him. She pulls the trigger, but surreptitiously uses her powers to make the gun misfire.
 * In Gunsmith Cats, bounty hunter Rally Vincent is asked to shoot a hostage with a gun with one bullet to prove she's in with the bad guys. She uses that one bullet to sever the ropes holding the hostage and shoot one of the hostage-takers in the leg.
 * Originally, the gun wasn't loaded at all, and she's such a gun expert that she knew it from the weight and called the bad guys out on it, that's when they gave her one bullet. It helped that she was not on particularly good terms with the hostage.
 * Subverted in Naruto: tells  to do this by killing
 * Early One Piece had Nami stabbing Usopp and pushing him into the water in order to prove her loyalty to Arlong. Of course, she was only pretending to do it, and stabbed her own hand to help with the ruse.
 * She was also told to shoot Luffy even earlier to prove her loyalty to Buggy. Short story shorter, she failed the test that time - lucky for the next 500 chapters or so.
 * In line with the Fumi-e process (listed under Real Life below), Hordy Jones' men force the people of Fishman Island to step on a picture of their beloved, assassinated Queen Otohime to prove their acceptance of Jones over the old monarchy. Somewhat subverted, in that Hordy Jones plans to kill those who had signed Otohime's petition even if they did go through the Fumi-e.
 * During the American Tour arc in Kinnikuman, Kin goes Charlie Brown From Outta Town to infiltrate an organization of evil Choujin. When the World Choujin Federation suspect 'Chanelman' of being Kin, they put out a picture of Mayumi, as part of a Fumi-e.

 * In Gundam Wing, Trowa infiltrates OZ by posing as a volunteer pilot from the colonies. When he demonstrates skill above and beyond the rest of the recruits, Lady Une instantly suspects that he's a Gundam Pilot trying to infiltrate OZ.

Trowa does so without hesitation, but is surprised to discover that doing so made him cry.
 * Used in Mariasama ga Miteru (of all things). Noriko denies that a string of Buddhist prayer beads belongs to her, so the other girls counter with "Then you should have no problem if they're destroyed then." Noriko balks, which makes Shimako (who lent them to her) confess that they're hers.

Comics
"Loki: "More to fear than me"! Oh Tyr, how fun this villainous talk is! (issue 625) Loki: And the Tongue will give it to us, or else I'll tear it out at it's bloody root. *turns to Ikol* That's the sort of thing I'm meant to say, yes? (issue 624)"
 * In an early issue of The Punisher, Frank Castle is attempting to infiltrate a drug cartel. He is given a gun with one bullet and told to shoot a narcotics agent the cartel had captured. He is also surrounded by several heavily armed thugs just in case he decides to use the bullet on someone else.
 * A more recent Punisher story had him infiltrating a white supremacist organization, and being told to prove his loyalty by killing a Latina reporter who'd been nosing around the group's hideout (who also happened to be his current tech guy's girlfriend). The twist is that the villain of the piece employs technology that enhances the aggression and anger of those exposed to it, which causes Frank to actually do it. He doesn't respond well to the tragic - if unintentional - lapse in his moral code.
 * An early Batman story featured Bats and Green Lantern attempting to infiltrate an evil group of fascists, but getting caught almost immediately. Batman is put through brainwashing while Green Lantern watches helplessly (devoid of his ring), and afterward, the final "test" to see if Batman truly has been brainwashed, is to hand him a gun and ask him to shoot Green Lantern. Which he does—but the gun isn't loaded, fortunately. As soon as the villain relaxes his guard, however, the heroes turns the tables on him and escape. Batman hadn't been brainwashed after all; he just knew that the gun wouldn't be loaded, since the villain wouldn't want to risk having Batman shoot HIM instead.
 * Of course, people tend to forget that though Batman Does Not Like Guns, he knows damn near everything about them. In less effed-up situations, he always knows when the Mooks need to reload - and in that particular one, he would have instantly known the gun was empty due to its weight.
 * In the first Deadshot miniseries, Deadshot is infiltrating a drug cartel for the Suicide Squad; he's asked to shoot a man they claim is an undercover FBI agent—and immediately does just that, to the dismay of his field commander Rick Flag. The FBI agent assigned to the case assures Flag that they didn't have an agent inside, but Flag points out that Deadshot didn't know that and in any case wouldn't have cared.
 * In one issue of Ultimate Spider-Man, Shang-Chi is applying undercover for the job of the Kingpin's bodyguard. Unfortunately, he fails the 'randomly kill that guy' test.
 * Played with in one New Gods comic that shows the origin of Granny Goodness. She was trained alongside a dog, who she bonded with. To graduate, her trainer ordered her to kill it. Instead, she turns around and kills him. Darkseid demands an explanation, so Granny responds that the dog was more useful, since it would obey her first, but Darkseid foremost. Darkseid commands the dog to attack her, and she kills it in self-defense. Impressed, Darkseid promotes her to her current status.

He does this in order to ensure that none of them will keep the notebook-if any of them try to keep it Rem is to tell them that they passed the test of bravery and that she had selected them to be the next Kira, and if they would just slaughter their families and fifty additional innocent people then they could have the power of Kira.

 * in Eastern Promises is implied to have done a variety of nasty things to get where he is.
 * In The Negotiator, Samuel L. Jackson plays a hostage negotiator who is framed for a crime. He knows most of his precinct is corrupt and probably in on it, so he takes hostages himself in order to attract the involvement of another precinct's negotiator, who he knows to be honest. In order to keep up the charade, he seems to execute an officer who came after him. Even the audience doesn't learn until much later that the man is still alive, merely bound and gagged out of sight.
 * The trope does not appear in Batman Begins, when Henri Ducard and Ra's Al Ghul instructs Bruce Wayne to execute a criminal in order to complete his initiation into the League of Shadows (naturally, Bruce refuses). The League is not challenging him to prove that he's evil—they are asking him to prove his commitment to a cause they think is right.
 * A rare passing grade can be found in Reservoir Dogs
 * An unusual example in Traffic: Catherine Zeta-Jones' character is asked to take a hit of the cocaine she's selling to prove it's real.

 * In the prologue to In the Line of Fire, Frank is meeting with his forger, Mendoza, who tells him that he had Frank's partner Al followed, and discovered that he was actually a mole for the Secret Service. Mendoza asks him to shoot Al to prove he isn't also undercover, which Frank does - but the gun is empty. Frank immediately shoots Mendoza's two accomplices and arrests Mendoza himself: He was undercover. Later, Al asks how Frank knew the gun was empty, whether he could tell by the weight of the pistol that it was unloaded. Frank answers
 * In the second Hellboy movie, there happens to be a monster disguised as an old lady who Hellboy and Co are trying to get info out of by pretending to be non-good monsters.

 * In Enter the Dragon, Han tests Roper's moral limits with a near-literal example of this by placing his own cat in a guillotine. Roper balks.
 * In The Parallax View, Joe Frady (played by Warren Beatty)--a reporter investigating a political assassination—notices all the witnesses are dying. After narrowly escaping an attempt on his life, he decides to allow people to assume he's dead (so he can go undercover). He finds a clue to the shadowy conspiracy in documents from The Parallax Corporation, some of which are a psychological test. With expert assistance Frady answers all the questions the way a sociopath would, and voila he's recruited as an assassin himself. From there, things only get murkier and more frightening...
 * In Bourne Ultimatum, Bourne is ordered to shoot a complete stranger at the end of his training. This is less to prove his evilness than to show obedience, but mostly the principle is the same.
 * Related to the Child Soldiers in Real Life, Blood Diamond has this done with Solomon's son, Dia, who
 * In Trade, Kevin Kline's character infiltrates an auction where a 13-year-old girl is being sold as a sex slave. When he wins the auction and goes to pick her up, her captors won't allow him to leave with her until he's taken her virginity. But since they don't insist on watching, he simply has the girl break her own hymen, so that when the captors check the bedroom and see the blood on the bed, they'll assume he had sex with her.
 * Stupid. One, why would they care once he's bought her, and two, why doesn't he just cut himself on the arm and save her the trouble?
 * In The Battle of Algiers, when Ali-La-Pointe first joins the Algerian resistance, he's given a gun and assigned to shoot a policeman. He tries, but the gun is empty, and he has to run away to avoid arrest; later he's told that it was a test; if he had been a spy, the French might have let him kill an Algerian, but not a cop. Of course, whether this is a test of evil or good or something else isn't a question the movie really lets you answer.
 * Amusingly, the test goes badly because he was too committed to the cause. He was ordered to sneak up behind a policeman and shoot him in the back. Instead, he angrily confronts the policeman and pulls the trigger of an empty gun.
 * In Inside Man, the lead detective (Denzel Washington) believes that the bank robbers are not murderers and therefore won't go through with any hostage executions. While inside the bank to check on the hostages, he insults the lead bank robber and attacks him specifically trying to provoke him into shooting him. When he leaves, he's convinced that he's proven his point... until they shoot a hostage in retaliation for his behavior.
 * In a variant from Dog Soldiers, one of the troopers washes out of training as a commando because he refused to kill the tracker dog sent to pursue him in a field operation. Not an infiltration, but a similar moral quandry that his commander berates him for shying away from.
 * A variation occurs in Pirates of the Caribbean: At World's End, when it's revealed that Cutler Beckett tested Davy Jones' loyalty by forcing him to kill his pet kraken.
 * In Queen of the Damned, when the other Ancients rejects Akasha's plans to subject the world again, she demands that Lestat kill Jesse to prove his loyalty to her.
 * Lampshaded in Hope and Glory where the hero proves his worthiness to join a boy's club by his knowledge of real swear words.

 * Later in Gray Lensman, Kimball Kinnisson needs to create a cover story so he can roam seedy mining colonies unnoticed. To that end, he decides, though it disgusts him, to start drinking and taking drugs. However, he approaches this very scientifically, studying his tolerances and behaviors as he prepares himself so that he never completely loses his mental capacity (which in the Lensman universe is your best weapon). He also avoids thionite as too dangerous and instead chooses a more-common and less-dangerous drug (a snuff-like substance called bentlam) as his apparent vice.
 * In a non-evil variant, an investigator in the (awful) horror novel Creepers poses as a destitute New York City tunnel-dweller. To prove his identity and grit to the head of an underground homeless enclave, he has to eat a fire-roasted rat, guts and all.

 * Played completely straight in one of Phillip Jose Farmer's Riverworld novels—taken prisoner by a group run by a Nazi, the heroes have the Sadistic Choice of being enslaved or killing another prisoner. Surprisingly, one of the heroes actually does it. (Two ameliorating factors: the hero in question was a caveman, and Death Is Cheap in Riverworld.)
 * In Sharpe's Tiger, Sharpe and Lawford are infiltrating the enemy by pretending to be deserters. To prove they're truly deserters, Sharpe's ordered to fire on a captured British prisoner (the same one they are supposed to be rescuing).

Face tries to talk his way out of it (claiming to have a twisted moral code that does not allow him to kill anyone unless he will make money from it) and Kell prepares himself for action in case Face's bluff fails, but Dia promptly takes the blaster offered by the Warlord and explains that she has no such moral code.

 * In Wen Spencer's Bitter Waters one of the characters is captured by a cult who think they are fighting a holy war against demons. They lock him in a room with a kitten. Their rationale is that if he eats the kitten he's evil, if he starves to death he's okay.
 * In The Fuller Memorandum by Charles Stross, the Nyar lath-Hotep cultists, believing Bob to be the Cosmic Horror that they're attempting to summon (It Makes Sense in Context), bring out the sacrificial infant intended for said Cosmic Horror.

Live-Action TV
{{quote| Willow: Oh yeah? Could a human do this [Screams her head off}
 * In an episode of the delightfully campy live action Batman, when Robin is offered a cigarette when he tries to blend in with some rough types.
 * This happens in the Angel episode "Power Play"
 * Previously, in the past, Angel had been given a similar ultimatum by his girlfriend, Darla. She noticed that after getting his soul back, he would only prey on murderers, rapists, and other lowlifes and evildoers, so she challenged him to kill a baby. He refused and decided to run away and bring the baby to safety instead.
 * In an earlier episode, in order to infiltrate a group of racist 'pure' demons (who look down on humans and hybrids, like vampire and werewolves) Angel actually SNAPS DOYLE'S NECK. However its revealed that Doyle, who is half demon, comes from a species that can actually survive this
 * An accidental (and fairly inoffensive) version occurs in "Guise Will Be Guise" where Wesley, pretending to be Angel, is handed a glass of blood. He tries to explain he doesn't usually drink blood in front of people but his host insists that he not mind them, and he reluctantly drinks it down.
 * In the one season '80s show Outlaws, the heroic time-traveling wild west outlaws with hearts of gold who are super rich from antique pocket money attempt to infiltrate an Evil Construction Company and are "invited" essentially to rape two serving girls to seal the deal. Upon their righteous refusal the Big Bad of the episode says something like "Betrayed by their own morals, here you have them, folks, the Good Guys!" (This is a bit weird because the only villainy they were attempting to impersonate was the Corporate Evil kind, and could have reasonably at least tried to fake squeamishness about violent assault.)
 * ... Like at the very beginning of In the Line of Fire where Clint's character tries to weasel out of proving his counterfeiter cred (by shooting his partner who they've realized is Secret Service but aren't sure about him yet) by saying "I'm a businessman!" (He does eventually pull the trigger, but the gun is unloaded and he gets his bust before saving the partner.)
 * Walker, Texas Ranger had a version where to get in to a group, a pair of undercover cops have to go with the gang to town to commit a crime. They're able to avoid causing real trouble by having a cop stop them and pretending to kill him, which is good enough.
 * A great (funny) example comes from the Buffy episode "Doppelgangland": When Willow is impersonating her vampire self and is asked to "prove it" she says, "I'm a bloodsucking fiend! Look at my outfit!" Later, when challenged again, she says, "A human? Oh yeah? Could a human do this?" and screams really, really loudly, signaling Buffy and Co. to rush the building and start with the ass-kickage. Absolutely hilarious.

Anya: Sure.

Head Vampire: Yeah, I think, yeah.

Anya: Humans do that.

The Scooby Gang storms in. }} "George: Shhh! Listen, you gotta do me a favor. Give me your wallet. I'll give it back to you later.
 * However an earlier played-serious scene lampshades the trope. Faith has told the Mayor that Willow is trying to hack into his computer files, so the Mayor decides that Willow must be killed. When Faith looks upset, the Mayor assures Faith that it's too early in her Face Heel Turn to expect that of her, and says he'll send a couple of vampires to do the job instead.
 * Inverted in the episode "Life Serial". Clem and his completely harmless demon buddies play poker for kittens, literally. The reason, according to to Clem? "They're delicious!"
 * On 24, Jack Bauer is frequently subjected to kitten-eating tests:
 * Season 3: To further validate his deep-cover identity in a drug cartel, Jack gets a gang tattoo and a heroin addiction.
 * Season 3 (again): The Salazars order Jack to kill his partner, Chase (who has no idea what's going on). Jack pulls the trigger, but the gun is empty.
 * Another Season 3 example,  decides to see if Jack has gone rogue or if he's still a government agent (and plotting her death), ... by making out with him? This is the test he actually fails, he returns the kiss, but she can tell he's faking it. Which is a nice bit of Conviction by Counterfactual Clue, since all that proved is that he still (justifiably) loathed her.
 * Season 4: Marwan gives the test to Dina Araz, ordering her to shoot Jack.
 * Possibly an homage to The Battle of Algiers
 * In short: Jack Bauer's real superpower is that half the time, he'll eat that kitten.
 * In CSI: Miami, a woman working with an undercover agent ends up murdered because 1) she refuses to take her dealer's heroin (she was pregnant) and 2) her handler refused to step in when she gave him the code phrase for "I want out".
 * One of these tests is given (off screen) to a Federal mole in the Salvadorian mafia on The Shield. We are later shown the carved up remains of the guy he was ordered to kill, showing that he "passed."
 * On another episode, Tina and Julian go undercover as an aspiring porn star and her boyfriend. When the director/drug dealer they were meeting with demands a blow job right there in his office, Tina manages to stall him until he implicates himself.
 * An episode of The Cleaner had Arnie infiltrating a biker gang. Unfortunately for him, they force him to smoke meth, his drug of choice before he got clean, to prove he's not a cop. Things... don't end well.
 * In season one of Wiseguy, deep cover agent Vincent Terranova is instructed to murder a federal agent to gain mobster Sonny Steelgrave's trust. He compliantly goes to the agent's house and shoots him.
 * Vinnie has another test later in the first season when he's infiltrating a different organization. Mel Profitt gets annoyed with one of the guests on his yacht and orders Vinnie to throw her overboard. Vinnie refuses. But it works out because Mel respects Vinnie for standing up to him.
 * Oz. Undercover cop Desmond Mobay uses various tricks to appear to be a user, such as palming or only partially snorting the drug. Unfortunately the inmates are wise to these tricks and force him to snort several lines of cocaine while they surround him. Later they tell Mobay that to join their gang he must kill someone. Mobay, who now has a serious habit, murders a corrupt cop who's threatened to expose him. He eventually confesses to the crime when it sinks in how far he's strayed.
 * In Law and Order SVU, Stabler faces this when he goes undercover as a suburban drug dealer. The drug syndicate he's "contracting" with to be his new suppliers tries to get him to sample some of his own product. Stabler hotly refuses, saying that his day job runs random drug tests. It works.
 * In another episode, Stabler, having gone undercover to gain the trust of a serial rapist, has to rape a woman that the real rapist kidnapped.
 * In a first season episode of Babylon 5, Sinclair is put in this situation, having infiltrated a fanatical pro-Earth group, and is asked to prove his sincerity by killing an alien (and one he met previously at that).
 * Also in one episode of Star Trek: Voyager, where the former Maquis crew members were forced to begin rebelling again by hypnotic suggestion, with the only one unaffected being Tuvok. He's handed a phaser and told to kill Captain Janeway. Tuvok presses the trigger and nothing happens. When Janeway asks him about this later, he answers, "They would not have given a person they were suspicious of an active weapon." Janeway finds this bit of logic to be... less than ironclad.
 * In an episode of Miami Vice, Detective Gina Calabrese is attempting to infiltrate a crime lord's organization by going undercover as a prostitute. The crime lord insists she has sex with him. To protect her cover, Gina agrees.
 * In an episode of Seinfeld, to avoid harassment by a street gang George claims to be a former member. They don't believe him so to "prove it" he has to mug somebody on the street. Jerry's parents walk by and George tries to get them to pretend he's robbing them but they dismiss him.

Morty Seinfeld: How're your folks?

George: Eh, they're trying to pick out a new couch - you don't want to know. (remembering the watching Van Buren Boys) Give me your wallet, or I'll spill your guts right here on the street!

Morty: What did you say?

George: Come on, hurry up, old man! I'm an animal!

Helen: You're being very rude. Come on, Morty.

George: Please, please, they're gonna hit me! (attempts to grab Helen's purse, she starts hitting George defensively, he backs off)

Morty: Tell your parents we said 'Hi!'"

"Neal: What were you going to do if I hadn't come in?
 * Subverted amusingly in one episode of Veronica Mars. Veronica actually tries to do this when she thinks she has found an Animal Wrongs Group, but it doesn't work out because the activists are the sensible, law-abiding sort who don't believe in extreme methods.
 * Used preemptively in an episode of Burn Notice. Sam, in his cover as a crooked cop, pulls the bad guy of the week over, hops into his passenger seat, and snorts a pinch of white powder before introducing himself. One of the show's signature voice-overs informs the audience that snorting a crushed-up lactase tablet isn't comfortable, but goes a long way toward establishing criminal credibility.
 * Not just Sam, but the whole crew use this trope frequently to maintain their cover identities with the bad guys. During the course of the show, they've yelled at, threatened, punched, and even shot at each other to prove whatever various identity they were under at the moment.
 * Averted in White Collar when an undercover-as-a-hooker Diana has to pick up a client to prove her worth and Neal steps in to play the part of her john:

Diana: Well, I'd have put this strawberry in that guy's mouth, taken him up to my room, put a gun between his ribs and told him to shut up and sit tight, or I'd arrest him for solicitation."

"Morgan: I told you, murder the puppy!' [hangs up] It's so hard to find good henchmen these days."
 * In the Criminal Minds episode "The Internet Is Forever" (5x22), in order to get accepted to the unsub's online club, which provides access to live footage of him killing people, prospective members have to download child porn onto their computers.
 * Caprica: Daniel Graystone's order to the U-87 to shoot his dog. He wasn't testing for evil so much as total amorality (or, more accurately, he hoped to see otherwise, indicating Zoe was inside).
 * In 30 Rock, Jack insists that anyone he mentors be truly ambitious, not just trying to get closer to him out of love and admiration. Thus, "if you're so ambitious, cut off my pinkie."
 * When MacGyver tries to join a pack of terrorists as a mole, he is given a gun and asked to kill another terrorist to prove his loyalty. Being a Technical Pacifist, he doesn't, saying that he despises leaders who are so eager to lose their men. It works.
 * A variant occurs in an episode of Human Target: the head villain of the episode doesn't know Chance snatched the actual hitman and is now pretending to be him. Still, this otherwise plays out fairly straight: Chance, undercover, is given the order to kill a prisoner... which he does. Then, when the boss leaves the room, he improvises a defibrillator and recuscitates the guy.
 * This happens a couple of times on Chuck.
 * While posing as a mafia hitman, Chuck has to torture Casey.
 * Casey takes this rather well, commenting that Chuck did him a favor by ripping out a tooth that had a cavity and saving him a trip to the dentist.
 * While posing as an arms dealer, Morgan invokes this on himself by pulling out his cell phone and orders someone to murder a puppy.


 * Jarod on The Pretender would face this kind of challenge when he went undercover as a shady occupation like hitman or bank robber. He'd always find a way to finesse the issue until he could bring the actual criminals to justice.
 * On Charmed, the episode "Wrestling With Demons" is about a demonic academy whose graduation ritual is killing an innocent.
 * Scarecrow and Mrs. King: In one episode Lee infiltrates a group recruiting burned-out agents to do their dirty work, who lure Amanda to their base and tell him to shoot her to prove he's genuine. He seemingly goes through with it; however it turns out that he'd purposefully missed and she'd had the foresight to fling herself into the ditch and play dead (allowing her to wait until they'd left and fetch help). The scene is used to highlight the trust and unspoken communication that has developed between the pair by this point in the series.
 * On Lost, Benjamin Linus has to participate in the Purge perpetrated by the group later known as the Others, so as to become one of them for good (or, should we say, for evil) ; which means helping to murder the entirety of the DHARMA Initiative people with gas poison, including his own father (whom Ben kills himself inside a van in a remote area – he later brags about killing all the people in the pit but he didn't do it all alone, and he didn't even give the order, which probably came from the leader, advised by Richard Alpert).

Music

 * The Dr. Dre song "187 (Deep Cover)" opens with Snoop Dogg forcing a guy to hit off a crack pipe to prove he isn't a cop.
 * Dance With The Devil by Immortal Technique. In order to join a gang, as an initiation, a guy jumps way over the Moral Event Horizon.
 * The "Christian test" (see below under Real Life) is parodied in DJ Kintaro's "FREE", where the Culture Police make people step on a vinyl record (vinyl being outlawed). The one who can't do it is hauled away.

Newspaper Comics

 * One Far Side strip, in which a jungle researcher's attempt to go undercover is met with: "So, you're a gorilla, huh? Well, then you wouldn't mind eating these grubs. In fact, we wanna to see you chug 'em."

Tabletop Games

 * In Dungeons & Dragons, the final test to join the Chaotic Evil Ravagers is to sacrifice an innocent to Erythnul, the god of slaughter. This serves as a means of weeding out good-aligned infiltrators seeking to destroy the Ravagers from within.
 * One default prerequisite for a character to take up the Assassin prestige class is that they must commit a murder for no other reason than to be accepted into the class.
 * In Alara Unbroken, the tie-in novel for Magic: The Gathering's Shards of Alara block, Rakka Mar offers to lead Ajani Goldmane to Nicol Bolas...if he'll slaughter all the friends he brought to help him search.

Video Games
"Tadakatsu"It matters not how many men you throw at me! I will fell them all!"
 * Samurai Warriors, Shingen Takeda to Tadakatsu Honda:

Shingen"And what if I threw kittens at you, Tadakatsu? Would you kill them, too?""

""That was wicked! Literally.""
 * Fallout has an example of this; to befriend some Raiders you must execute two girls they have taken as prisoners.
 * Splinter Cell: Double Agent. Sam Fisher is infiltrating the terrorist group John Brown's Army. He faces a Kitten Eating Test several times, including being ordered to kill three people (the helicopter pilot who helped him escape from prison, a CIA agent and his boss Colonel Lambert), and blowing up a cruise ship.
 * The order to shoot Colonel Lambert is also Shoot Your Mate.
 * This is what comprises the entire mission "No Russian" in Modern Warfare 2, in which you're undercover in a group of Russian terrorists as they massacre an airport full of defenseless civilians. You're not actually required to actively participate in the civilian massacre, but eventually the riot police show up and you inevitably have to fight through them to complete the mission. Trying to kill the terrorist leader results in a Hopeless Boss Fight of sorts, where the terrorist members become invincible and start shooting at you instead.
 * It gets worse: And even then, there's an even bigger reveal towards the end of the campaign.
 * Also, Modern Warfare 3 reveals that
 * Slight variation in TES: Oblivion—the Dark Brotherhood actively seeks out known murderers and offers them membership.
 * There's another Oblivion example. At one point in the main quest, you go undercover as one of the evil cultists you've been searching for. Turns out their initiation rite is sacrificing some poor sap to their god. It's very hard to save the guy as a statue falls on him if you just ignore him. Killing him when they ask you to makes the quest a little easier as it causes the audience watching you to leave. On the other hand, if you deliberately free him, or simply hack-and-slash your way in, you can save the victim and he will reward you later.
 * In Fable II the entrance exam of the Temple of Shadows used to be something easy like kicking the crutches out from under a lame man. Nowadays, you have to eat five whole live baby chicks RAW with the sort-of evil guy commenting on how horrible it is.
 * Not to mention the very effective Spire scenes in Fable II, in which
 * In the first game, a Demon Door has similar requirements—he won't open unless you "perform an act of great evil in front of him..." unless you're fully evil at the time, in which case he remarks that you "wear your evil as a shroud!" and opens immediately.


 * In World of Warcraft, some quest lines have you undermine evil guys. Not all of them make you do really evil stuff, but a particular quest line in Zul'Drak definitely qualifies; slaughtering an entire village of trolls and subjecting their chieftains to cruel experiments. One may argue that the trolls are evil anyway but they are definitely less of a threat than the Scourge.
 * Death Knight starting zone. The troll evilness is a sort of interesting case because the person actually giving the quest isn't evil so much as very cruel and vindictive. Neutral Jerkass more than Neutral Evil. So you're actually doing a good thing here, not proving your credentials.
 * Being a Blood Elf embodies this Trope. One early meme was that a usual quest was "Kill this kitten. FOR FUN!"
 * There's a questline in Stranglethorn Vale that involves joining the Bloodsail Buccaneers(temporarily, you won't lose your Booty Bay reputation). To prove that you're on their side you must kill the fleet master in Booty Bay and bring them his head.
 * Arthas, after revealing he was a Death Knight publicly, ordered Thassarian to kill his own mother to prove his loyalty. So he did.
 * Either subverted or played absolutely dead straight in Knights of the Old Republic, depending on your Karma Meter position. In order to gain full access to the Sith school on Korriban (and therefore the Star Map in a tomb there), you have to demonstrate yourself to be a hard-ass bastard in the true Sith style by destroying assassin droids, executing runaway students, and betraying pretty much every other student. The subversion is that while you can behave like a murderous bastard by betraying and murdering your rivals, you can also do what any good undercover Jedi would do: cheat like crazy. You can fake the deaths of the renegade students, calm the assassin droid with a conscience down, and even redeem the ghost of a Sith Lord from centuries ago and still get in. You can even get the Star Map and then lecture the leaders of the Academy about how their backstabbing ways let you accomplish it all.
 * In probably the best example of subversion you stumble into a Sith mentor testing some students. They suck so he ponders on a proper punishment for them: death or torture- and turns to you for an advice. You can approve violent chices OR you can tell him to simply let them go. Just because that's what you want. If you manage to push it across hard enough the Sith is impressed with your Badassitude and vehement adherence to Sith MO and indeed lets them go.
 * The second Quest for Glory game has this in the form of a test to join the Eternal Order of Fighters, by having you kill a man after defeating him in a trial by combat. If you kill him, you get a higher rank in the EOF, which has absolutely no in-game benefit; if you spare him, you get a lower rank, but the in-game Karma Meter gets points and he speaks on your behalf in the finale, which can earn your character the title of Paladin.
 * Of course, whether you decide to or not, the man stands up alive and well after the fight is over.
 * In Baldur's Gate II, you can try to complete one quest nonviolently. However, the people you're trying to get an artifact back from will want to know you're loyal to their cause, and ask you to praise Talos, the Chaotic Evil Forgotten Realms god of storms. If you do, you're struck by lightning (though it doesn't necessarily kill you) and the battle begins. (The meeting takes place outside.)
 * Unless your main character actually is a priest of Talos.
 * Hilariously, if you're wearing the cloak that reflects lightning, the ostensibly god-sent bolt bounces back and incinerates the guy you're talking to, ending the conversation prematurely and stopping the normally ensuing fight scene.
 * And of course there are the . Though, it is possible to cheat in the one quest where you actually have to kill some innocent people.
 * Amusingly, during the drow kitten-eating quest,
 * In the second Free Space game, in order to prove your loyalty when working as a spy amongst the Neo Terran Front rebel faction, they dare you to gun down a civilian transport. If you refuse (by waiting), they brand you a traitor and a spy and try to kill you. If you accept and destroy the ship, they call you heartless but say they knew you were a spy and try to kill you.
 * Due to a mission scripting oversight it doesn't actually matter in the end what you do here. If you destroy the civilian ship you get a severe reprimand from your superiors, are told that you're to be tried for treason, and generally implying the end of your career as a pilot. However the game still considers the mission a success and allows you to continue through the campaign as if nothing happened.
 * The Chzo Mythos has the Order of the Blessed Agonies' Agony of the Soul, where someone must prove their loyalty to the cult of pain by killing someone they love and rely upon.
 * Early in the Mega Man X manga, a maverick attempts to convince X to kill a human girl to prove he's a not a "traitor" to the reploid race. X is not pleased.
 * In Metal Gear Solid 3,
 * This is especially tense since we know
 * In the Evil Ending of Neverwinter Nights 2, you must prove you have no allegiance to your former party members by killing them all singlehandedly.
 * In 'The Shadow Odyssey' expansion pack for EverQuest 2, one quest to infiltrate a group of troll pirates involves getting ordered to kill an arena full of kittens. If you choose not to do it, you can stuff them into a sack and hide them, instead. The dialog for not killing the kittens has your player telling the troll that you ate them.
 * In Batman: Arkham Asylum, you can overhear one of Joker's goons telling the others that Joker once ordered him to kill his sister to prove his loyalty. He says that he did it, and that he'd been looking for an excuse to do so for years anyway. Another mook one-ups him, saying that Joker made the same request of him even though he had no sister, and wouldn't leave him alone about it until finally he killed a random woman and brought her body to Joker, claiming her as his sister.
 * While not really a test of evilness, in 7.62 High Caliber, the first thing the rebels demand of you is to kill a captured government official. If you refuse, they will kill you (as you're heavily outnumbered and outgunned). The problem arises when you have a mission to save that same official. The solution is to, thus causing both sides to like you more.
 * In The Elder Scrolls V: Skyrim, the initiation to join the Dark Brotherhood involves killing one of three individuals tied-up with bags over their heads. However at least one of them is an Asshole Victim. The Dragonborn can also Take a Third Option and kill Astrid, which changes the questline to hunting down the Dark Brotherhood instead.
 * Several Daedra Lords require you to murder people in order to receive their artifacts. Boethiah plays the trope straightest, as he requires you to prove you can be treacherous by murdering someone who trusts you on his altar before he'll even speak to you.
 * Played with in Portal. Most players will remember Test Chamber 17: the home of the famed Companion Cube. GLaDOS coaxes Chell to use the cube in various ways to get through the test, then, in typical GLaDOS fashion, springs the trope on her by indicating that in order to complete the test, she has to "euthanize" the Cube by dumping it into the incinerator. Barring Cargo Ship, most players just get it over with since the Cube isn't alive, but GLaDOS keeps on implying your "evil" nature once you finish: "You euthanized your faithful Companion Cube more quickly than any other test subject on record. Congratulations."

Webcomics/Web Originals

 * In The Legend Of Anne Bunny, which is very loosely based on real history, Anne is told she can't join the pirates until she kills someone. She claims to have already done it, and at least one pirate believes her. Later she confesses otherwise, but they decide she's cool off to have around anyway. Heck, they.
 * Fluble parodies this in a scene where Mack The tells Fluble that women will only date scum. When Fluble insists that he can be scum, Mack The challenges him to eat a puppy. Fluble falters, Mack The eats the puppy and is immediately surrounded by women.
 * Dr. Horrible's Sing-Along Blog: "He rides across the nation, the thoroughbred of sin. He got the application that you just sent in. It needs evaluation, so let the games begin. A heinous crime, a show of force, a murder would be nice of course..."
 * And more so later: "So now assassination is just the only way. There will be blood, it might be yours, so go kill someone. Signed Bad Horse."
 * Team SMASK (a Doctor Who macro fanfic), to test John to see if he wants to enter the league of evil characters, he is told to shag the Racnoss. He complies.
 * A dramatic example in Equestria Chronicles; Icarus, established as a kind and loving pony, is told to execute a prisoner in front of the entire city. On penalty of death. While his Dad looks on. He's given five minutes to prepare.
 * Axe Cop: In comic #137, Axe Cop and Dinosaur Soldier try to enter the villains' secret lair, which is guarded by a giant evil head. They decide to go undercover as bad guys to get in, but the head demands that they kill a good guy to prove their badness. Luckily for them, Mr. Stocker, the useless superhero with no powers, shows up... and Axe Cop, being written by a young child, isn't one for moral dilemmas. (They can always have Uni-Man bring Mr. Stocker back to life if they need him again.)

Western Animation
"Cobra Commander: Why did you save him? Do I detect a vestige of mercy?
 * The Tick (animation) is the Trope Namer, in which the eponymous hero and his sidekick are attempting to blend in with a bunch of Obviously Evil villains to pump them for information on the location of The Enemy Awards. The Forehead gets suspicious of their villain credentials and tests them with this line. The Tick fails the test immediately. As seen here.
 * "Eating kittens is just plain wrong! And no one should do it! EVER!"
 * A heroic variant comes up in Justice League Unlimited, or rather, a character's back story. Shining Knight, a knight in modern times, relates that he was tasked to raze a village to the ground by his lord King Arthur. Knowing Arthur couldn't have been so evil as to ask that, so he let them live. In return, he is rewarded for thinking rather than obeying blindly. He uses this as a metaphor for why the Shaggy Man/General Eiling is using flawed logic when he considers all super humans a threat, and only blindly obeying "duty", regardless of harmed Innocent Bystanders, mattered.
 * Inverted in South Park's retelling of Great Expectations. Pip wants to prove that Estella isn't evil and gives her a bunny and insists there's no way she could kill it. She does. Pip gives her another bunny and she kills that one. This continues for a while, and only stops because she gets bored. Which is lucky, because he'd just run out of bunnies.
 * In Samurai Jack, Jack once had to blow up a house to enter a criminal gang. He did it, but sneakily evacuated the inhabitants first.
 * To elaborate, the house was inhabitted by a kindly old man and his many cute kittens and puppies. As soon as he opens the door, Jack looks despondent.
 * In The Simpsons, when Bart is undercover in Shelbyville, the local kids ask him to write the graffiti "Springfield sucks" to prove himself. He seems to obey at first but really paints "Springfield rules, suckers!" instead, effectively blowing his cover with style.
 * Another episode had Burns adopting Bart and tested him to fire Homer (and drop him in a trap door). In a Crowning Moment of Heartwarming, Burns ends up getting dropped.
 * In The Powerpuff Girls, the girls pretend to join the side of evil. As a test, Mojo Jojo shows them a cute little plushie and then steps on it...repeatedly. The action causes Bubbles to scream (and faint) and Blossom to look on, horrified. Buttercup, on the other hand, was all too happy to join in on the plushie-stomping...
 * In another episode, Bubbles dresses up as Boomer to spy on the RowdyRuff Boys. Brick puts her through a series of tests, including shooting a snot rocket and eating a cockroach.
 * Totally Spies! featured this as a brainwashing test. Unable to step on a randomly (and illogically) present mouse, Alex kicks the lone instructor in the face.
 * In Beast Machines, Jetstorm challenged Thrust to prove his loyalty to Megatron by extracting Blackarachnia's spark. Thrust almost did it, but was interrupted by Nightscream, forcing Jetstorm to do the deed himself. This becomes rather disturbing when later information is revealed.
 * When Dusty on G.I. Joe was sent to infiltrate COBRA as The Mole, Cobra Commander has him fight a Mook in gladiatorial combat. He's told the battle is to the death, but wriggles out of having to kill the man in cold blood by humiliating the Mook instead. He even has an answer when he's called on it:

Dusty: We can always use extra help on K.P."

"Robot Devil: Wow! That was brutal, even by my standards!
 * In the Season 4 episode of Venture Brothers, "Bright Lights, Dean City," Baron Underbheit thinks he needs to do something along these lines to join the Revenge Society. So he, without hesitation, snaps his manservant's neck. Turns out they just wanted him to sign some forms.
 * There's a literal example in Catscratch, when one of the cats is pretending to be a dog, and has to prove it by EATING. A CAT.
 * Happens in the third Futurama movie, or maybe it's a subversion? A stoogic trio of villains are masquerading as "owl-exterminators" as part of an evil plan. Professor Farnsworth presents them with an owl to exterminate, to prove that they they are not villains in disguise. However, they are not evil/competent enough to kill the defenceless creature, and thus they fail the test and reveal themselves to be villains.
 * This also happens in the second movie, when Bender wants to make a deal with the robot devil to get an army of robots to attack Yivo's dimension. The Devil tells him that a deal such as that will require a very evil act from Bender - giving him his first born son! Bender does it. The Robot Devil is impressed.

Bender: No backsies!"


 * Kittens give Morbo gas.
 * In the Swat Kats half-episode "Cry Turmoil", T-bone feigns allegiance to the eponymous villainess, Turmoil, until Razor is found running around Turmoil's airship. Turmoil is suspicious, until T-bone volunteers to show his loyalty by personally tossing Razor off the ship.
 * The trope is parodised in its fullest in Duck Dodgers when the Cadet is made into the lord of a race of Klingon-like aliens. When the dethroned leader brings him dessert, it turns out to be... a live kitten. And this is not a deliberate test, their race really considers kittens a delicacy!
 * My Little Pony Friendship Is Magic, "Dragon Quest": Spike tags along with a dragon migration, and falls in with a pack of rowdy teenage dragons. They drag Spike into helping them raid a phoenix nest, and when they manage to find an unhatched egg they dare Spike to break it to prove he's a "real dragon".
 * Adventure Time has the episode "Web Weirdos", where Finn and Jake get caught in a spider's web along with two insects. When the spider couple comes back, Finn tries to convince the male that he's not in cahoots with the other food just trying to escape, to which the spider says "Well okay then, eat your friend here." to which Finn then pretends to eat one of the insects.

Real Life

 * The only way to really get into and higher in the Mafia or most gangs is to kill someone; one of the reasons why is to weed out any undercover cops trying to get closer to the boss.
 * An undercover cop trying to gain access into the Hell's Angels faked the murder of a rival gang member who supposedly 'killed' his undercover cop friend through the use of good old fashioned Hollywood makeup and effects. It worked well enough that they offered to make him a full member of the gang. They pulled him from the assignment just before his induction however because they feared for his safety. The entire account was detailed in The History Channel series Gangland.
 * Some prison gangs, such as the Aryan Brotherhood, use a "blood in, blood out" system in which new members must commit a murder to join, hence rooting out undercover cops.
 * Prevalent when there's an undercover cop around—ranging from "snort this cocaine" (yeah, like an undercover cop isn't going to do coke if the alternative is being killed) to "kill this guy" (including Shoot Your Mate).
 * Note that undercover cops have the authorization to break the law in order to maintain their cover, including participating in major felonies, but killing is still not allowed. The only catch is that they have to report it ("Yes, he told me to snort coke to prove I wasn't a cop, so I did.").
 * A persistent urban legend, attached to military organizations ranging from the World War II-era SS to the modern US Marine Corps, states that recruits are trained alongside a dog, and encouraged to form a bond with the dog. In order to graduate from training, they are forced to kill the dog. All evidence shows this isn't actually true of any of these organizations, but plenty of people believe it is.
 * The "Unsullied" eunuch warriors in A Song of Ice and Fire have the dog training thing.
 * According to the GSG9 trainer on Deadliest Warrior, they apply this trope. With chickens.
 * There is a joke where various military men are attempting to join a Special Forces group, on their final test, they are ordered by their commanding officer to go into a small room, close the door, and shoot a man (or in some versions of the joke, their wife) tied to a chair inside. Most of them enter and get out, saying they can't do it, and are turned down (or, usually in the version with the wife, accepted, as it was a Secret Test of Character). The last man goes in, and grunting and yelling is heard. He leaves the room, panting. The commanding officer asks what happened, and the man says "This damn gun's filled with blanks, so I had to beat him to death with the chair."
 * Sometimes the version with the wife further elaborates that there are three guys—one from the Army, one the Navy, and the final one from the Marines. The first two can't do it; the Marine, however, notes the blanks and beats her to death with the gun.
 * The story goes that a speakeasy owner was on the verge of catching Isidore "Izzy" Einstein and Moe Smith, revenue agents (Prohibition police) in 1920s New York famous for their efficiency, doggedness, and antics in pursuing a case. The owner asked Einstein, who was known to be an observant Jew, to eat a ham sandwich, thus "proving" he wasn't Izzy Einstein. Moe distracted the target while Izzy hid the ham, and ate the sandwich.
 * To get into child porn rings, you have to bring your own kiddie porn. Of course, real cops can't (for obvious reasons), which makes it hard to gather evidence (stolen logins are fair game, though).
 * Most of these investigations are done by the FBI or by Postal Inspectors; they have access to child pornography seized in previous cases. Occasionally, defendants' convictions are overturned on the grounds of entrapment, if they can prove they weren't predisposed to the crime.
 * If materials were seized from another criminal, it's generally considered acceptable to turn around and use them as part of cover for a sting operation, just as real drugs are sometimes displayed in drug stings to help reinforce cover stories. As long as there is a thorough paper trail of what happens to the materials and said materials are not redistributed, the materials are considered to be just for show, much like fake IDs. As long as the cops keep playing by the rules, judges and juries will consider the sting above board.
 * In Isolationist Japan (between the early 1600s to sometime after Commodore Perry "visited"), Christianity was outlawed. During this time, areas suspected of harboring Christians got visits from the Emperor's men, who rounded up the locals and ordered them to step on a plate... one bearing an image of the Crucifixion. If you refused (or in some cases, hesitated too long), they took you away, and you usually didn't come back. This practice was called the Fumi-e.
 * Medieval Shi'a Muslims, as an oppressed minority in Sunni lands, engaged in the practice of taqiyya, which permitted them to lie about their faith (or fake the devotions of the Sunni majority) to preserve their own life. Theologically, this was not permitted if it resulted in the death of another innocent. The Hashshashin were alleged to engage in this practice.
 * Similarly in Bulgaria, even today, nodding your head means 'no' and shaking your head means 'yes'. This is because when the Ottoman Empire took over the Turks wanted to kill the Christians so they would ask 'are you Christian?' and a shake of their heads to their oppressors came to mean 'yes'.
 * A Brazilian psychologist went to work as a trash collector for a few months as a study on how they're viewed by society. The other garbagemen put him through a short test by offering him a drink in a can from the trash (he didn't fool them, they just wanted to see if he had guts).
 * Replacements for at least some Japanese regiments in China during World War II were initiated by killing a bound prisoner with cold steel. "I noticed, when I sheathed it, that my sword was slightly bent." (source: Japan at War: An Oral History by Haruko Taya Cook & Theodore F. Cook)
