I Cannot Self-Terminate

""I cannot self-terminate. You must lower me into the steel.""

- The T-800 cyborg

Perhaps the Body Horror has almost completely taken over a person and with their last ounce of humanity, they beg to be killed. Perhaps they've just been wounded in a vital area and know they are going to die slowly and in agony, and just want to die with dignity/end the pain quickly. Perhaps they're losing the battle with an Enemy Within and they need the hero or sidekick to throw the airlock switch/fire the Forgotten Superweapon at them/lower them into the steel. Perhaps they are prisoners and being tortured, and the hero cannot break them free but could shoot them. In any case, while they're ready or even eager to die, they cannot do it on their own. This can also count as a Heroic Sacrifice, sometimes.

If, like the page quote, the character is robotic, this may occur due to influence from Asimov's Laws. Specifically, a robot may not harm itself, or through inaction allow itself to be harmed, unless it is in direct opposition with the first two laws. Even when not following the hierarchical laws of robotics, it could still occur if a robot is simply programmed for self-preservation.

In a series set in Jidai Geki, this trope may appear when a Samurai character commits Seppuku—ritual suicide—to redeem himself. Traditionally, a person committing seppuku, after disemboweling himself, was allowed to have a "second" (kaishakunin) behead him before the pain would destroy his composure. (Itto Oogami's original position in Lone Wolf and Cub was as an official "second" for the Shogunate.) Sometimes, the "second" will volunteer for the job, as a token of respect for a friend or Worthy Opponent.

Instant Death Bullet is likely. Then, usually the killer has no difficulty getting to a position and attacking in a manner that would cause quick death. When the character is Fighting From the Inside, but not very effectively, the death can be long and gruesome. (See page quote.)

The victim may plead for death even when it is possible for them to be saved, owing to the pain. The hero is likely to override that, often saying No One Gets Left Behind.

Compare to Mercy Kill, when the target cannot even request death; Death Seeker, where the target can't even find anyone willing (or capable, if the Death Seeker still wants to fight to the best of their ability); and Driven to Suicide, when they can self terminate. Also compare Trial by Friendly Fire.

 * In Tekkaman Blade, the main character has a strict 30-minute timer on his battle form before he loses his mind and becomes a savage destruction machine. Early in the series, he asks another member of the team (his Lancer in the group, Noel) to shoot him if he goes over.
 * Very cruel example from Saint Seiya:
 * In Dragon Ball, this is the reason Kami trains Goku to kill Piccolo Jr. Since he and Piccolo are two halves of one being, if Piccolo dies, Kami will as well. Kami feels that he deserves to pay for bringing Piccolo into the world in the first place, but as a God, he can't kill himself.
 * In the end of Code Geass,  However...
 * The writer has stated that
 * And let's not forget
 * Poor Suzaku, who wants to die so badly… in Suzaku of the counterattack, at one time the easiest way to save the universe is him absorbing immortality power!
 * C.C., being immortal, fit this trope until near the end of the series. In fact, the "contract" she makes turns out to be.
 * In the Tournament arc of Yu Yu Hakusho,
 * Well, to be fair,
 * Early on in Bleach, Orihime's Hollow-fied older brother Sora has a flash of Heroic Willpower, removes his Hollow mask and asks Rukia to perform konsou on him before he hurts anyone else. (Mild subversion, since technically he's already dead, but the afterlife concept in Bleach is weird as hell anyway.)
 * And later, we learn that this is not the first time Rukia has done that.
 * Gungrave: In the anime
 * In Gash Bell the demon-bookkeeper pairs cannot burn their own books; therefore there were many cases of demons(or their bookkeepers) asking others to burn their book for them. It could be either because any more damage to the demon could actually kill the demon(their bookkeepers would rather have the demons sent back to the demon world than having them die) or because they do not feel like participating in the battle anymore.
 * In Fullmetal Alchemist, doctor Marcoh is being held prisoner by the homunculi and made to work for them under threat that if he doesn't cooperate or dares to run away or kill himself they will obliterate the village where he spent the last years in hiding..
 * Kaworu Nagisa of Neon Genesis Evangelion is a blatant example of this.
 * In Baccano!, this is the ostensible reason immortals were given the ability to "devour" others. It took at least a few minutes seconds before they realized they could use it to murder each other, though at least two immortals have considered asking Firo to end their lives this way.

 * Yu-Gi-Oh!: Done in a weird way in the series finale..

Comic Books

 * In part two of the classic Alan Moore "Imaginary Tale" ("...Aren't they all?") Whatever Happened to the Man of Tomorrow?? which brought an extra-continuity close to the Silver Age Superman mythos, Lex Luthor's body is essentially possessed by the disembodied head of Brainiac, which he is forced to wear like a rather macabre helmet. When confronted by a temporarily superpowered Lana Lang (who, pre-Crisis, he had some history with), Luthor valiantly struggles against Brainiac's control long enough to beg her: "kill me!", rather than remain the living computer's meat-puppet. Lana complies and snaps Luthor's neck... but (unfortunately for Jimmy Olsen) even the death of his host body wasn't enough to keep Brainiac down, as he manages to continue stimulating the corpse's nerves and muscles for a while longer, Luthor's head grotesquely lolling to one side on its broken spine. Eventually the rigor mortis catches up with him, forcing the malignant robot head to dismount and crawl, Krang-like after Superman with futile murderous intent before finally expiring. Best villain death EVER.
 * In The Sandman, retired DCU hero Rainie Blackwell (AKA Element Girl), who feels alienated from humanity due to her transmutation powers, longs to kill herself but can't because regardless of the method she chose her body would automatically transmute itself into another substance. Death of the Endless, having failed to talk Rainie out of dying before her time, suggests she ask the Egyptian god Ra, the source of her superpower, to handle it. Ra silently tells her to look directly at him, whereupon she disintegrates.
 * At the end of the series' take of the tragedy of Orpheus and Eurydice, Orpheus is beset upon by the furies and reduced to an Oracular Head. He requests that his father Morpheus kill him, because as a divine being he can't die naturally or be killed by a mortal. Morpheus denies him and leaves him alive as a severed head.
 * In an old Batman comic, Batman is possessed by Manuel, a dead Satanic-worshipping pirate, who's trying to bring himself and those stuck in purgatory back to the real world. Batman pleas with The Flash to kill him before that happens. Luckily, the Flash chooses to Take a Third Option.
 * A similar example to the above occurs in Lucifer. Due to a promise she broke as a temple maiden, a Babylonian woman is punished with immortality; as a particular condition of the immortality, every day for the last four thousand years has featured her miscarrying her fetus. She ends up seeking out a bargaining chip for Lucifer, who revokes the immortality and watches as she blows away to dust.
 * In X-Men, Professor X had been mostly transformed into an alien Brood (the Brood life cycle: an implanted embryo takes over the host's mind and eventually transforms their body) but when the X-Men managed to take him down he had enough control to beg Cyclops to kill him. Cyclops' response was essentially "Screw that, I'm Taking A Third Option."
 * 2000 AD's Rogue Trooper encounters a subverted version of this trope. Having thought that he was the last remaining super-soldier, he is amazed to find a much older prototype living as a hermit on the poison-choked planet Rogue roams. The old man says he is waiting to die and that he feels like nature is going to take its course very soon. When enemy troops approach, Rogue's friends - personality-chips of fallen comrades embedded in his helmet and gun—vote to leave the old man to his fate. Rogue declines—the old man wants to die with dignity—and his already impressive abilities are ramped up to eleven in order to massacre the enemy patrol and give the old man something Rogue hopes to have himself one day.
 * A History of Violence.
 * A story arc of Fantastic Four has the Thing, being possessed by Dr. Doom, put the Torch in a death hold. Doom is laughing that the only way to stop him is to kill him—that is to say, kill Ben. Ben manages to wrest just enough control to tearfully tell Reed to do it. For once, Reed gets stuck in a situation where he can't Take a Third Option.
 * In Uncanny X-Men Annual #6, Rachel Van Helsing (from The Tomb of Dracula) is turned into a vampire by Dracula. Throwing off Dracula's mind control long enough to (temporarily) kill him with a spear, she then asks Wolverine to kill her with a wooden stake. He does so.
 * In X-23 #11, X-23 asks Jubilee to kill her if she succumbs to the "trigger scent" to prevent her from killing innocent people. Predictably, Jubilee doesn't follow through and it leads to an "I Know You're in There Somewhere" Fight.
 * Inverted in French comic Les Légendaires. The Big Bad points out that he's a god. In this verse, only gods can kill gods, and other gods have deserted this planet. So, he states that the only hope for the heroes is that he would suicide.

 * Starship Troopers, Rasczak, the leader of the Roughnecks, informs all of his new recruits "I've only got one rule: everybody fights, no one quits. You don't do your job, I'll shoot you myself."

He tosses his rifle to Rico and screams for him to "Do it!" which prompts Rico to empty the magazine into Rasczak.

 * Dawn of the Dead remake has, being devoured alive by zombies, pleading CJ to shoot him.
 * In the most tragic scene of John Woo's The Killer (besides the ending), the title character's best friend Sidney, after delivering the money he needs to have Jenny's eyes fixed and being shot by the main bad guy's men, asks for a last bullet from his friend so that he doesn't die like a dog, because he didn't save his own last bullet for himself. The Killer tearfully complies.

 * In X-Men: The Last Stand, Jean Grey asks Wolverine twice to kill her as she senses the Phoenix taking over. The second time, the request is fulfilled.
 * The quote above comes from the film Stargate: The Ark of Truth. Merrik, possessed by replicator, is briefly given back his free will after being electrocuted.

 * In the end of The Fly, Seth Brundle, now fully transformed into a hideous fly/human hybrid is trying to get out of a telepod after Stathis managed to free Veronica, but he gets teleported along with bits of the broken pod and emerges as a fly/human/metal thing, dying and in agony. He, or rather, it, crawls up to Veronica and gently directs the shotgun she is holding to his head so she could end his suffering.
 * Subverted for the ending in End of Days, wherein Arnold's character is possessed by Satan himself, but before he's forced to rape the girl he tried to protect during the movie, regains control long enough to jump straight on a sword held by a statue, killing himself and banishing Satan just as the year 2000 rolls along.
 * In Serenity, River is in the middle of an emotional breakdown while handcuffed to the floor, and begs for Simon to kill her, interspersed with images of her with a gun to her head. However, he immediately rejects that.


 * Inadvertently applied to David from An American Werewolf in London, because the restless spirits of his victims waste so much time dreaming up ways for him to kill himself that he runs out of time to act on their advice and succumbs to another transformation.
 * The Great Waldo Pepper has the title character's friend trapped in a burning airplane after a crash. When Pepper is unable to free him, he begs, "Don't let me burn!" Pepper then euthanizes him with a blow to the head.
 * The 1990 comedy Short Time stars Dabney Coleman as a police officer who erroneously finds out he has a terminal illness. The problem is, his wife (Marge in Mom and Dad Save The World) only gets his pension pre-retirement if he is killed in the line of duty. Since suicide is also out of the question, he starts taking massive risks on the job in an effort to get a perp to kill him.
 * Debatable in the case of The Hitcher, in which serial killer Ryder keeps asking protagonist Jim to "stop me", and gives him several opportunities to kill him. Questionable as to whether Ryder is simply looking to die, as per this trope, or if he's specifically trying to make Jim into a killer like himself.
 * The protagonist in the 1986 horror/comedy House is troubled by memories of Vietnam, and especially his own failure to carry out a Mercy Kill when a trap-snared friend invoked this trope. Sure enough,

Clint: (through Billy) Don't listen to this coward! Billy: I can't take this anymore! Clint: Shut up! Billy: Shoot me! Shut up, shut up, shut up!"
 * In Callahans Crosstime Saloon, Michael Finn was sent by an alien force to determine whether Earth is so dangerous that it needs to be destroyed; however, he's decided (after an evening at Callahan's) that he likes us Puny Earthlings. Should he fail to report in, they will assume we destroyed him and stay well clear of us—but it's impossible for him to intentionally fail to report, as long as he's properly functioning. When he gives his name as Michael Finn, Callahan the bartender takes the hint and slips him a "mickey", which renders him unconscious during the assigned reporting period. (Also of note here is that Michael himself refers to his mission as a "geas.")

 * In Dan Abnett's Gaunt's Ghosts novels,  is handed over to the Black Ships. Several books later, he communicates with Hark, who finds him, cries (which all the deaths in all the books have not drawn from him), and at his request, kills him. (He makes it look like an execution at   request, to save himself.)
 * In JRR Tolkien's The Silmarillion, when Fingon tries to rescue Maedhros from Morgoth after Cold-Blooded Torture, and it looks like he won't succeed. (However, in the end, Fingon frees him by cutting his hand off.)
 * Self-preservation is Isaac Asimov's third law of robotics, making it the third-most-important moral imperative for a robot. Unfortunately for the robot, it's overridden by one and two, so a robot can kill itself if ordered to do so.

 * In Lois McMaster Bujold's Chalion novel The Hallowed Hunt,  is perfectly capable of killing his current body—too bad his soul and consciousness will simply jump to the body of his next living heir, devouring that individual's mind in the process.

 * In New Moon, second in the Twilight series, Edward wants to kill himself because he thinks Bella is dead, but because he's nearly impossible to kill, he has to go to the Volturi to ask them to kill him.
 * Specifically, he was going to reveal his Bishie Sparkles to the city, somehow revealing the existence of vampires and forcing the Volturi to kill him.
 * Which is a bit confusing, since the vampires of that series are described as basically stone statues with lighter fluid for all bodily fluids and immolation as the only surefire way to kill one of them. He should have been able to just set himself on fire to kill himself.
 * Horace McCoy's They Shoot Horses, Don't They? ends with Gloria asking Robert to shoot her because she can't bring herself to commit suicide. He complies, and later when the cops ask him why he did it as they're taking him away, he offers the title phrase in reply.

 * The Dalek in the Doctor Who episode "Dalek" was developing more emotions than just hatred - a situation its species could not stand. It had to be ordered to die by someone else, as its training would not let it commit suicide under other circumstances. Rose finally (and reluctantly) gave the order.
 * Beth, in the Torchwood episode "Sleeper" couldn't actually kill herself because of her position as a sleeper, but because of the grief she'd caused herself, she to force the team to kill her.
 * The humanoid Cylons on Battlestar Galactica Reimagined are forbidden from committing suicide by their religion (although at least two have successfully self-terminated by putting themselves in close proximity to explosives); given the overall tone of the series, it is perhaps not surprising that this has led to multiple instances of Cylons begging someone else to pull the trigger on them. This appears to be purely a psychological effect rather than something hardwired into them - Brother Cavil, the one Cylon who doesn't believe in the Cylon god, is shot by the underground resistance on New Caprica in the third season, and, upon coming back sometime later, casually mentions that he had to cut his jugular vein open with a shell casing to kill himself. And he does it again in the final episode as well, "Frak!" * bang*
 * Keep in mind that "real death" is clearly regarded differently from being killed and resurrected.

Considering that his son is a young child raised by humans, this convinces Worf to try the experimental surgery to fix his back.
 * Subverted in Supernatural. In season two episode "Born Under A Bad Sign" Sam has just killed a hunter and is pleading with Dean (who obviously can't) to kill him before he gets any worse. It turns out that . At the end of season four in "When the Levee Breaks",, Sam tells Bobby to shoot, moving the gun's muzzle to his own heart, if Bobby wants to help him.
 * Played straight in "Heart." Sam's one night stand was a werewolf, but they cured her... except not. There's no cure and she'd already killed a few people, so she asks Sam to shoot her instead. Ouch.
 * In season 4 of Angel, the titular character asks Connor to kill him if his Super-Powered Evil Side gets free. He does this in private though, so when it inevitably does the others think he still just wants to kill Angel.
 * Angel has pretty much asked this of anyone who's ever worked for/with him. Most of them kind of suck following through on it.
 * BRUTAL subversion in Lost. They tried to do this to the marshal, but the one bullet they had left missed the heart, and it would have taken him hours to bleed out, had Jack not euthanized the marshal some other way (offscreen.)
 * Richard enlists Jack's help in committing suicide in "Dr. Linus," since he cannot do it himself.
 * In the fourth episode of Dead Set,.
 * Power Rangers own iconic Zordon is a rather justified example: he wanted to commit suicide by way of a Heroic Sacrifice in Power Rangers in Space, but needed to convince someone else to help him do it as he lacked, you know, limbs.

 * In The Sarah Connor Chronicles episode "Ourselves Alone," Cameron's continued uncertainty about her own ability to control her actions following the damage to her chip prompts her to
 * The early FOX series Werewolf would have been one episode long if Eric's roommate had committed suicide rather than invoked this trope. Eric's failure to comply fast enough when his friend transformed is how he got bitten himself.
 * Near the end of the second season of Farscape, Crichton incoherently rambles about how he's trying to do something but the mind-control chip in his head won't let him and vaguely gestures at a gun amidst scattered chess pieces. When his best buddy D'Argo presses the matter, ("Do WHAT, John!?") Crichton asks D'Argo to kill him.
 * Over the events of Charmed, Cole managed to escape hell and return to his beloved wife Phoebe. Unfortunately, the the powers he had absorbed to achieve this only caused problems for her and her sisters, so she ended up divorcing him. To his dismay, he found that his powers had also made him Nigh Invulnerable, and, as such, rendered him unable to kill himself from the grief. He even started causing trouble for the girls in a bid to get them to vanquish him for him.
 * Only to subvert this trope when he explains that he just wanted to try whether he really was indestructable and goes Ax Crazy for good after the confirmation.
 * The insurgent prisoner from Over There:

After they introduce the next season's Big Bad by way of him threatening to kill George if Mitchell doesn't leave with him (and help him commit further horrible crimes), George does it. Of course, he'll probably be back...
 * An episode of the Outer Limits remake featured a scientist who tinkered with nanotechnology, and made himself nearly invincible. Unfortunately, the techniques his body used to protect him gave him a monstrous appearance, and proved potentially harmful to those around him.
 * In Community, Abed is incapable of stopping himself from humiliating others, he has too give out "destruct codes" for himself.
 * In the Criminal Minds episode "Reckoner," a judge suffering from terminal cancer hires a hitman to carry out a series of Vigilante Executions on people he considered Karma Houdinis (mostly for crimes against children), culminating in the man who killed the judge's wife while driving drunk. After the last criminal is killed, he admits to the BAU that there is still one more name on his hit list...and is promptly shot dead by the hitman.

Music
"If I wait, this could die [If] I wane, this could die I want you... to take me out!"
 * Franz Ferdinand's "Take Me Out" at least sounds like it's describing such a situation.


 * Ice Age's "Dead But Wide Awake" very clearly describes this

 * In Roman mythology, a famous Sybil (please note, that's the title of a seer/oracle, and is not yet used as a name in Rome) from the nearby city of Cumae was turned into a cicada by Apollo when she refused to sleep with him. Cicada!Sybil was ostensibly kept in a cage in the temple of Apollo at Cumae, where people would continue to ask her questions; one day a young child asked what she wanted, and she replied that she wanted to die.

Radio
""Kill me." "I can't!" "Kill me." "I love you!" "Kill me.""
 * The Dalek in the Big Finish Doctor Who audio Jubilee had had its self-destruct system disabled and, more than just ordering it to self-destruct, the Dalek demanded that Evelyn actually shoot it with its own gun.
 * The Eighth Doctor himself in the audio play Zagreus, echoing Charley's request in the previous story.



Tabletop Games

 * Dwarfs in Warhammer Fantasy Battle are an interesting example, in that their culture allows for death to atone for a terrible shame or failure, but is strictly opposed to killing oneself- according to some sources, dwarfs are mentally incapable of suicide. Instead, a suicidal Dwarf becomes a Troll Slayer, which mostly entails dyeing their hair and beard, cutting it into a mohawk, and going out to find something really nasty to kill them in battle. And since Dwarfs are similarly opposed to throwing a fight, the more successful (or unsuccessful, depending on how you look at it) Slayers are fearsome warriors indeed.
 * Amusingly enough, the normally-branching "career paths" detailed in the Warhammer RPG handbooks break down slightly for Trollslayers. A Trollslayer's only "exit career" is "Giantslayer," and a Giantslayer's only possible exit career is "Daemonslayer," each one describing a correspondingly higher level of Awesome. And under the listing for "exit careers" for Daemonslayers...? "A glorious death."
 * The Sisters Repentia from Warhammer 40,000 are similar to the Trollslayers. They are made up of Sororitas who have somehow shamed themselves and seek redemption through death in battle. They are essentially naked women toting gigantic chainsaw swords whose only purpose is to charge the nearest enemy and cut it to pieces.
 * Then there's "the Emperor's Peace," which is simply a mercy killing, used In-game by Space Marine medics on other members of their squad; the rest of the squad just forgets about them.
 * Young Erasmus van Richten of Ravenloft invoked this trope, begging his father Rudolph to drive a stake through his heart before vampirism could extinguish his compassion and make him a killer. Justified in that, while Erasmus could theoretically have committed suicide by sunlight, he was only a kid and probably couldn't have endured the 10 rounds of agony then required under D&D rules.

Theater

 * In Shakespeare's Julius Caesar, Brutus asks for one of men to hold his sword so he can run himself on it, as his Stoic philosophy forbids him from directly committing suicide.
 * Either a case of Did Not Do the Research or Science Marches On however, since Stoic philosophy actually prescribes suicide as an honorable death (second only to death in battle) and that allowing someone to commit suicide rather than execute him was oft reserved for the Worthy Opponent as a way of letting him go out on his own terms. The offer was more often taken than rejected.
 * Brutus does a similar thing after the Battle of Phillipi in the series Rome. He dismisses his guards, takes off his armor and marches straight at the advancing enemy soldiers, sword in hand. At first the soldiers just block or dodge his attacks, but when he wounds one, they stab him to death.

Video Games

 * In one quest in Jade Empire, you encounter a man who has been infected by cannibalistic demons and begs to be killed before he becomes a cannibal as well. You'll actually gain a few "Open Palm" points on your Karma Meter if you kill him; if you don't, he succumbs to the infection and you'll have to fight him.
 * Bioware likes this trope. In Dragon Age: Origins, the main character will encounter a Dalish elf who has turned into a werewolf. Her transformation has left her in excrutiating pain and she will beg the character to end her suffering. If you do, she will thank you. If you don't, she will attack and force you to kill her.
 * Star Wars: Knights of the Old Republic II takes the trope further: not only can't an HK-series assassin droid self-terminate, it also can't harm other HK droids because its programming still considers other units to be parts of itself.
 * You wouldn't be able to find that out without restoring some of the cut content, though.
 * The original, Japanese version of this appears in both Tenchu and Sword of the Samurai II, where the player character can end up acting as the 'second', depending on various factors.
 * A notable occurrence in Tenchu involves infiltrating the manner of a corrupt lord. Once you finally reach him, he repents and asks for your help. He then stabs himself in the stomach, and you take off his head.
 * In Half-Life 2, Gordon comes across humans who have been taken over by headcrabs. They beg for death even as the headcrab forces them to attack the player.
 * They're actually whimpering, "GOD HELP, HELP ME!" backwards, and damn if it isn't creepy as hell.
 * Shadow's flashback dreams in Final Fantasy VI shows him being asked by his partner Baram to kill him, as he was mortally wounded and couldn't do the deed himself. Shadow freaks out and runs away, leaving Baram to die slowly and painfully.
 * General Pepper in Star FOX Assault. The Aparoids have taken over his ship and threaten to take over himself as well. During the fight, he keeps asking to be killed before that happens. Subverted in that Peppy dives in to soften the ships fall and Pepper survives in the end. Also later in the game,.
 * In an astonishing example of loyalty,  in Wild ARMs 3.
 * In the 3D shooter game Duke Nukem, Duke comes across various attractive young women with Body Horror problems who beg you to kill them.
 * Given the nature of Duke to "borrow" lines from other sources this is very likely a "shout out" (cough) to Aliens.
 * In Breath of Fire 2, the main character will discover his long-lost father attached to a machine in the bowels of a dungeon. He asks you to kill him which you can do during the boss fight immediately after his request but the game also subverts this trope by allowing you to solely attack the machine during the battle instead. This will result in the machine destroyed, the father saved, and you on the path towards the best ending.
 * In Killer7,
 * Happens in Castlevania: Harmony of Dissonance in one of the bad endings. Juste finds Maxim barely holding on to himself, and Maxim begs Juste to kill him before his Enemy Within takes over. Juste refuses, and (predictably) Maxim's evil side does take over, and you have to fight him.
 * In another Castlevania example, Soma made Julius promise to kill him if he ever loses out to his Super-Powered Evil Side. It's unusual in that it's the protagonist that makes the request.
 * Yet another Castlevania example: In Lament of Innocence, the origins of the Belmont family whip are revealed, as Leon
 * In System Shock 2, the annelid hybrids (humans who have been assimilated by The Many) will often beg you to kill them, even as they attack you.
 * In BioShock (series),
 * In BioShock (series) 2,
 * Nobody is mentioning
 * In Oni,, after being   activated, she repeatedly says things like "I'm so sorry!" and "Konoko, kill me, please!" while trying to shoot you. After breaking free,
 * Cave Story has When the protagonists find him at the end of the Bonus Level of Hell, he begs, "Kill me! Or I--shall kill YOU!"
 * Happens twice within the Path of Radiance/Radiant Dawn continuity of Fire Emblem. The first time is when Bertram, a boss in Path of Radiance, enters battle with incoherent babbling that seems to be a plea for death. The second, more notable one, is, who set up the entire scenario with Tellius being subjected to Ashera's judgment because he wanted to be destroyed with the rest of the world.
 * Also a third time with Notable in that
 * In Thief 2, you encounter a near dead and more then half frozen Pagan. After speaking to the Pagan, he asks you to do one last thing for him: end his pain. In a moment that touched my heart, Garrett called the Pagan his friend just before he killed him.
 * He obviously has a death wish, since he'd prefer freeze to death rather than drink any healing potions dropped into his lap.
 * Deus Ex - A secret room in Morgan Everett's compound reveals his ageing predecessor, Lucius De Beers, sealed in a life-support system and acting as an advisor for the Illuminati. De Beers is under the impression that, when he recovers, Everett would allow him to return to power. The player has the choice to inform him of Everett's true (and rather bastardly) intentions. De Beers promptly pleads Denton to pull the plug as he'd rather die than divulge any more wisdom to his usurper. You don't have to, though.
 * Final Fantasy X : Tidus' father, Jecht aka the monstrous Sin, although it doesn't come as a surprise to Tidus, who spent most of the game coming to terms with the fact that he'll have to kill his father. Still, even though Tidus always claimed his dad was an idiot, it hurts him when Jecht asks him to do it quick, because there's not much of his own mind left.
 * World of Warcraft features a couple of bosses that are under the effects of Mind Control or, in the case of Thaddius, are a horrific patchwork construct, and either before, during, or after the fight, beg you for death or thank you for killing them.
 * A good example is the final boss of the Nexus, Keristrasza. She's a Red Dragon captured by Malygos, the leader of the blue dragon-flight, after she aids the players in a quest chain and is bent to his will and he takes her as an unwilling consort eventually driving her insane. During the fight with her, she'll at one point say "Finish it! Finish it! Kill me, or I swear by the Dragonqueen you'll never see daylight again!"
 * In Prey, Tommy finds his girlfriend Jen but she has been fused onto a monster and he is forced to fight her. In the end, she begs him to kill her.
 * In Gears of War 2, Dom, after spending the better part of fifteen years searching for his wife Maria after losing her during the chaos of Emergence Day, finally finds her to be alive, well and as beautiful as the last time he saw her.  You can guess what happens next. This scene was particularly impressive in that Gears wasn't the most emotionally deep of games, up until around that point.
 * In Tales of Vesperia, Estelle begs Yuri to kill her before she causes anyone anymore pain while she is under 's control. He
 * When Chris finds Forest in the (definitely strange but oddly... effective in a certain way) Resident Evil Pachislot game, when he gets up as a zombie, it can be made out in his standard undead moans that he's asking to die - Chris apparently misses it, since his retaliation is regretful, but when he makes it, the zombie also thanks him right before the bullet/round hits. Also, in 3, there is one scene where one of Carlos's fellow U.B.C.S. members is infected and tries to convince him to kill him, which he finally does just as he starts to turn.
 * The video game Dead Rising has a scene to this effect. Brad ends up getting zombified in the most physically graphic way possible in the game (you can see the parasites eating his intestines). When Frank finds him Brad states "It doesn't even hurt.. I'm already dead, and then proceeds to hand Frank a pistol while asking "Don't let Jenny find out, okay?"
 * In Soul Nomad and The World Eaters, ends up asking the main characters to do this, as the alternative is.
 * Fortune from Metal Gear Solid 2 is unwilling to kill herself, and wants to die in a blaze of glory in a battle against Solid Snake, whom she blames for her father's death. Unfortunately, Fortune has luck that prevents her from ever dying in combat, and every grenade thrown at her is a dud. This is a major motivator behind her constant Wangst. The Boss Battle against Fortune plays on this trope heavily; you spend it dodging her shots and taking cover until the timer runs out.
 * A variation on this trope appears in Metal Gear Solid 3: Snake Eater, in which
 * Vamp starts displaying signs of this trope in the fourth game, but it's not due to any sort of moral dilemma; he is literally unable to kill himself, since he instantly recovers from any wounds,
 * In Star Ocean: The Second Story, Philia's programming makes it impossible for her to commit suicide.
 * Prometheus repeatedly begs Kratos to kill him to end his cycle of torment in God of War II.
 * One theory states that GLaDOS puts Chell though hell because of this trope, in order to give Chell motivation to kill GLaDOS.
 * Miang, the quasi-Big Bad of Xenogears is unable to kill herself (it's never really explained, but it is probably some form of in-bred psychological programming by Deus that leaves her unable to take her own life), despite being virtually immortal thanks to her ability to Body Surf. Instead, she manipulates her former superior and lover, Ramsus, into killing her so she can.
 * Rita from Galerians is unable to kill herself and begs Rion to do it for her, likely for reasons similar to what a robot's would be, though she's not one.
 * This trope is built into the gameplay mechanics of the 2008 Prince of Persia reboot. The Prince cannot die either in combat or during the acrobatic sections of the game. Even if you intentionally throw yourself of a cliff, Elika will save you and take you back to the last flat ground you stood on. Even when facing off with the dark god Ahriman he cannot die because Elika will save him. It's even used as a story element at one point: in order to beat the Concubine's illusion, he tosses himself off the top of a tower because he knows Elika is compelled to save him.
 * In Deadly Premonition, the shadows will sometimes shout "Please kill me!" or "Make me die!" when attacking.
 * In Planescape: Torment you come across a woman who is dying of a painful illness but whose race has a taboo against suicide, and who requests that Dak'kon (a priest—sort of—of that same race) end her suffering. You can use this as an opportunity to psychologically torture him.
 * In The Suffering, Torque finds a prison guard- or more accurately, the torso and head of a prison guard who has had his limbs and tongue chewed off by rats, locked in a padded room. You can either leave the blood-gurgling man there to suffer, or kill him, whereupon your dead wife will applaud your decision and grant some karma points towards your ending.
 * A variation occurs as part of a minor quest in the Shivering Isles expansion, where an Imperial named Hirrus Clutumnus in Crucible asks you to kill him. He's perfectly capable of doing it himself and would be happy to, but doesn't want to end up on the Hill of Suicides like the others before him. Fortunately, he happens to spend time on the rail-less staircase to the New Sheoth palace grounds...
 * Unfortunately, like many other characters, he responds to being pushed out of his scripted position by trying to return to it, making it more likely that the player character will slip past him and fall off the stairs himself.
 * In the Morrowind expansion Bloodmoon you find a Nord looking for a path into Sovngarde, the Nordic version of Paradise. As it turns out,
 * At one point in the Meet the Medic video for Team Fortress 2, the BLU Spy's disembodied head is seen stuffed in the back of a refrigerator. He's on screen just long enough to deadpan "kill me" before the Medic shushes him with an irritated "later!"
 * Shining Force II's Lemon, who goes on a killing spree as the Red Baron, snaps out of his trance and now wishes to atone for his sins. However, since he is no longer human, he finds that he can't kill himself. The first time he attempts suicide, he tries jumping from a cliff, with Astral commenting "That couldn't have felt good".
 * In Warhammer 40,000: Warhammer 40,000: Fire Warrior
 * In Quake II, there are levels where you see captured humans being experimented upon. "Make it stop" and "Kill me now" are two rather common sounds.
 * In Neverwinter Nights 2, the dragon Nolaloth has spent millenia 'living' as a ghost, bound to the Prime Material Plane by an artifact called the crystal heart. He asks you to destroy the heart so he can finally make his way to the afterlife.
 * In Final Fantasy XIII, this trope is the driving force behind
 * In Final Fantasy XIII, this trope is the driving force behind

Visual Novels

 * Saya no Uta, with  whom Saya has... modified.
 * Fate Stay Night has lose in a fight to Shirou. She calmly asks to be finished off, warning that she will likely heal in time to stop him should he not. If you choose to spare her, she does just that.
 * realizes that she needs to be stopped, but will only allow Shirou to do it.

Webcomics

 * The so-called Suicide Fairies from Gunnerkrigg Court. Upon meeting Antimony, they almost immediately ask her squish them flat with a rock. As it turns out, dying is a test they must pass to gain new bodies and enter the Court. Outright killing themselves (or each other, apparently) constitutes cheating.
 * This series of Penny Arcade comics utilizes the trope in a very efficient fashion. The Cardboard Tube Samurai must kill one of his oldest friends when he becomes possessed by an evil sword.
 * Vexxarr: ...and now they cannot.
 * This is why Pices of the webcomic Zodiac joined the team of superheroes. Having been gene-spliced with an alien Eldritch Abomination, he wants to ensure that, should he lose control, there is a team of superheroes ready to take him down.

Web Original

 * In Survival of the Fittest Version Three, this happens with    is severely wounded by , and pleads for death after the wound worsens when another creature rips it apart.
 * In Ruby Quest, requests that Ruby detach her from the life support equipment which has kept her alive in an And I Must Scream situation for over a year, and refuses to allow Ruby to proceed any further until she complies.
 * In the SCP Foundation SCP-735 is unable to move. It torments people, using words, possibly in an attempt to get destroyed. Unfortunately for it, if this is its goal, it probably isn't going to happen. the Foundation likes to horde SCPs that it doesn't consider to dangerous, and it is robust enough to withstand any personal that attempt to destroy it long enough for that personal to be stopped.

Western Animation

 * In the South Park episode "Fantastic Easter Special," Jesus and Kyle have been imprisoned in the Vatican. Jesus realises that if he dies, he can resurrect himself outside the bars. He's unable to kill himself, as suicide is a sin, so he asks Kyle to do it. After initially refusing ("I'm a Jew. We have a few hang-ups about killing Jesus."), he reluctantly agrees, on the condition that "Eric Cartman can never find out about this."
 * "Oh, and Kyle? Happy Easter." "Happy Easter, Jesus."
 * In Venture Brothers episode "Midlife Chrysalis," when Rusty has been turned into a giant caterpillar due to an injection Dr. Girlfriend has given him, he tries to get Helper to shoot him. Helper refuses.
 * Sergeant Hatred also begs Doctor Venture to kill him after his wife hints at wanting to leave him, and can't do it himself because he is "a warrior, and will die by the hand of [his] archenemy". He eventually pulls himself together and.
 * In the Samurai Jack episode "Jack And The Lava Monster," the titular "monster" turns out to be a norse warrior who was cursed by Aku; placed in a crystal prison. He eventually gained the power to control the earth around him, and created a Death Course for the purpose of finding the warrior who could defeat him in battle, allowing him to finally pass on to Valhalla with the rest of his comrades. Most telling is his anguished cry of "I must be defeated honorably! I cannot let up!" during his fight with Jack.
 * In the episode "Trouble in Lumpy Space" of Adventure Time, there's a conversation where Finn thinks Jake (in the throes of the Lumps) is about to request this of Finn, should he go completely Lumpy. Yes. They actually got away with referencing this. It's never actually stated, and it turns out that Jake just wanted Finn to still be friends with a Lumpy Jake. "What did you think I was saying?"
 * Gargoyles never directly brings up the issue of suicide, but the reason Macbeth keeps picking fights with Demona is because she's the only one who can cancel out his immortality. The thing is, she's fated to die too if she ever kills him, leading to an awkward situation whenever he forces her into a battle.

Real Life
""How's this for tomorrow's headline? French Fries!""
 * Interestingly, while Seppuku is frowned upon now, there is still a large cultural mindset in Japan towards self-punishment for dishonor. Although it doesn't usually reach I Cannot Self-Terminate levels, it can result in an odd (for Westerners) predeliction towards redemption.
 * The kaishakunin or "second" in a seppuku ritual has a role somewhere between this and Mercy Kill. He decapitates the person committing seppuku after the cut is made, to kill the seppuku performer before the pain becomes so great that he cannot help but dishonor himself by showing pain.
 * There were quite a few Roman Catholic samurais during the Sengoku period. As a result, they cannot commit seppuku due to religious reasons even it would be culturally appropriate to do so. The alternative is suicide by opponent soldier.
 * The case of Sue Rodriguez, a landmark decision in the Canadian euthanasia debate. Rodriguez suffered from ALS and feared that by the time she reached the point of wishing to die, she would be unable to carry it out herself; she took her case to the Supreme Court twice but was struck down both times. (She eventually died in 1994 with the assistance of an anonymous physician.)
 * Similarly, the case of Ramón Sampedro in Spain. He became paralyzed from the neck down after breaking his neck in an accident as a young man. Unable to commit suicide on his own, he spent years fighting for the right to assisted suicide, and was repeatedly denied by the Spanish government. He eventually died in 1998 with the help of friends, each of whom performed a single act so minor that they could not be charged with a crime.
 * In a weird way, this trope is why people get cancer. Normally, once a cell becomes cancerous (i.e. its DNA has mutated to the point where the cell cannot control its growth), the immune system will recognize that this happens and will essentially force the cancerous cell to self-destruct. The Warburg Hypothesis is based on the observation that most tumor cells have damaged mitochondria, which then disables the cell's ability to destroy itself. As a result, it can continue to grow unabated and cause problems while the body's defenses are unable to stop it.
 * A real life example, one of the theories behind the Malaysian phenomenon of "running amok," was that it was a suicide attempt. Because of the taboo towards suicide, a man would retain his honor by attacking as many people as he could until someone who finally kill him, since he could not kill himself.
 * Truth in Television example: The phenomenon of "police-assisted suicide," in which people who can't bring themselves to end their own lives commit a violent crime, such as taking a hostage, in order to provoke the police into shooting them. Only officially considered "suicide" if the person left a note to that effect.
 * Historically, dueling probably served the same purpose.
 * Actually dueling was never meant to be lethal, men dueled because it was "cool" and because they wanted to have battle scars. (And was we all know Chicks Dig Scars)
 * Perhaps for sword duels in some countries. Pistol duels were rather more dangerous, though.
 * Serial killer James French was sentenced to life in prison. He wanted to die, but was afraid to commit suicide - so he murdered his cellmate, and subsequently, was executed. He also had some hilarious Famous Last Words:


 * Filling out a living will may invoke this trope, depending on what criteria are incorporated into it.
 * The purpose of the Dignitas clinic in Switzerland.
 * Botched suicide attempts in general. Enough said.
 * The state of Oregon has the Death With Dignity act, which allows terminally ill people to end their lives by self-administering lethal medications provided by a doctor. The state of Washington has a similar law.
 * Assisted suicide is still officially treated as homicide in Britain, but the office of the Director of Public Prosecutions (somewhat similar to a district attourney in the United States, but at what in the US would be considered a federal level) has issued a statement to the effect that if they are satisfied that the perpetrator acted with the informed consent of the deceased, they will not seek to press charges.
 * Good practice in computer systems is a user who has the maximum privilege cannot delete their own account from that account, they must delete it from someone else's account that also has maximum privilege (basically so that an administrator doesn't accidentally delete the last or only account having maximum privilege and thus making it impossible to perform whatever action requires that privilege.)
 * When a cell in the human body is infected by bacteria, the cell will chop the bacteria up and stick the pieces out on its surface, couched inside proteins that basically say "Hey killer T cells, this thing is inside me, please kill me and record who did it".
