(nervous laughter) "All the better! Cases are so much easier when the bad guy offs himself like that."When the hero is spared the burden of dispatching the villain because the villain engineers his own death or defeat. While the monsters of the week have the decency to be sufficiently inhuman, anthropomorphic, faceless and irredeemably evil that the heroes feel no guilt over slaying them (so polite!), human enemies are another story. What exactly is the hero to do when he captures Cleo the Necromantess? Tell the police to arrest her for stealing chunks of Soul Anatomy from Innocent Bystanders, cursing them to endless nightmares? It's hard to prove that in a court of law. And even if a high-ranking member of the police is a Secret Keeper who can get Cleo jailed for other charges, what prison could hold her? Then there are the villains who are remorseless, sociopathic killers. You know that nothing but death will prevent Saul the Fingerchopper from killing again, but If You Kill Him, You Will Be Just Like Him... When a hero is faced with someone who cannot be dealt with through legal channels, his morals come up hard against practical circumstances. Killing Saul is right out, but letting him go free will just result in more victims. The Big Damn Villains or a killer even more evil than Saul won't always be around when you need one, and sometimes you can't Seal Evil In A Can. The Chosen Many Corps or The Men in Black might occasionally come through and lock Saul up with their high tech/mystical imprisonment, but you can't count on that every day. And while the hero may have his powers lost/stolen every other episode, permanently Depowering a villain is rarely ever possible for an unsympathetic villain. (And let's not even get into Brainwashing for the Greater Good...) So an idealistic hero may find that the very morals he stands for are a serious hindrance to effective peacekeeping — a tricky situation with no easy solution. This might actually be revealing a controversy in the morals — but good luck explaining that to viewers — or the guardians of the said morals. The hero could be in serious trouble except for one helpful fact: a human villain about to be defeated usually goes straight for the Villain Ball. Instead of begging for mercy and "playing nice" for a few episodes, Cleo and Saul will double down. When Saul is rescued from hanging off the cliff's edge and given a Last-Second Chance, he inevitably takes the opportunity to backstab the hero (who then reacts in self defense when he cuts Saul down). When Cleo is defeated while holding the Artifact of Doom, she will never simply drop the thing and 'surrender'. She will scream "No! This Cannot Be! I just need more power!!!", bringing on the Superpower Meltdown that destroys her. In short, the heroes will not have to bear the burden of killing because these villains will inevitably cause their own downfall. Their excessive egos and poor planning will turn on them at exactly the wrong moment and get them Hoist By Their Own Petard, sent to a Fate Worse Than Death, or destroyed by their own death traps. They can also take themselves out nonfatally, ending up Depowered, amnesiac, in a Convenient Coma, or trapped in a Tailor-Made Prison. The purpose of this trope is to resolve the villain's menace without going into the moral complexity of what justifies taking a human life. As such, it often appears in series where killing would be wildly inappropriate for the target audience or tone of the setting, such as works for children. When it appears in more adult fare, it is there to enable a certain kind of hero — a Knight in Shining Armor or someone with Incorruptible Pure Pureness — to deal credibly with Cleo and Saul without tarnishing his image. Conveniently, this trope also keeps the hero's secret identity secret if the villain had discovered it. The aftereffects of the Phlebotinum she was using (or even a simple Tap on the Head) will immediately make Cleo forget any damning information she may have uncovered. It might even make her forget she is a villain. A big part of the appeal of this trope is that it makes for a smooth but satisfying resolution. Once Saul has dispatched himself, the hero and his party can walk to the nearest Burger Fool and order a Delicious Extra Meaty without feeling the slightest pang of guilt (well, except maybe over the empty calories in the fries). If they're particularly Nice Guys, they might feel a little sad that Saul got himself killed/trapped/disposed of — but whatever; it's not like he won't be back in the next episode anyway. Compare Disney Villain Death, which similarly disposes of a villain for good while leaving the hero's hands clean. If you were looking for the trope about a literally self-disposing body, see No Body Left Behind.
As a Death Trope, all Spoilers will be unmarked ahead. Beware.

Anime and Manga
- Johan Liebert of Monster holds a boy hostage and forces Tenma to make the Sadistic Choice of killing him or letting the boy die. Then the boy's father conveniently shows up armed and suddenly it's a moot point.
- Sailor Moon: The major villains (Quirky Miniboss Squad and up) have a tendency to either kill each other off for various reasons (You Have Failed Me, You Have Outlived Your Usefulness, Evil Versus Evil) or be destroyed by their own technology/attacks, leaving the less human looking Monsters of the Week and Big Bads to be destroyed by the heroes. This is especially true of the Witches 5 from the S season. Eugeal is killed by Mimet, Mimet is killed by Telulu, Telulu is killed by her own plant, Byruit is killed by her own nanobots, and Cyprin and Petirol actually end up killing each other in battle. The Sailor Scouts never have to do a thing.
- Although Sailor Moon was the one who caused Byruit's nanocuff to backfire, and Sailor Jupiter and Sailor Mars tricked Cyprin and Petirol into killing each other
- Exceptions are Malachite/Kunzite and Emerald.
- Note that this is only in the anime; in the manga, the Senshi had no qualms about killing the human/human like villains.
- The Sailor Scouts never seemed unwilling to kill them, it was just karma that most of the major villains killed each other. Sailor Moon tried to kill Jedite twice, and Neflite before Molly stopped her.
- From Rurouni Kenshin, Kenshin Himura was usually pretty good about making friends of enemies or convincing them to otherwise not be evil. But when he goes up against foes who are irredeemable, they usually get killed by someone else or wind up dying mid-battle.
- In Monster Rancher, Naga is defeated by Mocchi, and is hanging onto the edge of a cliff. The heroes try to save him, but he lets go on purpose. The Fox channel skipped the episode because of this.
Moo: Now I understand. You and I are destined to eternal battle for as long as we live. In that case, I can't let you exist. Nor myself!
- Ironically they did not skip the episode where Undine jumps into the fire and burns to death.
- General Durahan is taken out by his own troops who are loyal to Moo, whom Durahan has betrayed. And shortly before that, he kills Lilim.
- Moo appears to partially self-destruct when he and the Phoenix destroy each other, based on this line:
- In Pokémon Diamond and Pearl, Cyrus, the season's antagonist, walks into a portal leading to a dimension he possessed Dialga and Palkia to create, despite the fact that the dimension was slowly vanishing due to Dialga and Palkia being released, thus killing himself. (Even if Dialga and Palkia directly destroyed the dimension sooner than it would have taken to disappear on its own)
- In Dragon Ball, when Staff Officer Black learned that Commander Red, leader of the Red Ribbon Army, was going to use the almighty Dragon Balls to wish himself taller and made all the sacrifices of his men thus far look like they died for the sake of dog crap, it set him off enough to put a bullet right between the commander's eyes in utter disgust for his moronic leader, saving Goku and company the trouble of taking him down.
- In Dragon Ball Z, virtually all of Frieza's henchmen are offed by Vegeta except Bund and Vug (killed by Krillin and Gohan), a few mooks who are killed by three Nameks, Blueberry and Raspberry (who are killed by a giant crab), any who remain on Planet Frieza or travel with King Cold (killed by exploding building and Trunks, respectively), and some mooks who are killed by Frieza or Captain Ginyu, which also fits the trope.
- Dr. Gero has his head crushed by Android 17
- Nappa is killed by Vegeta for losing a battle to Goku
- Majin Buu kills Babidi when he becomes tired of his abuse
- Van Zant is the first victim of Evil Buu. And when he becomes Super Buu, Smitty gets it.
- Averted with Cell. He self-destructs, but is able to regenerate From a Single Cell.
- The final battle of Kill la Kill has Ryuko foiling Ragyo Kiryuin's Evil Plan and wanting her to come back to Earth safe, since she's her mother. In response Ragyo rips her own heart out of her chest and crushes it, spreading away the remaining Life Fibers in a possible Sequel Hook. For an anime called KILL la KILL, the heroes sure don't do a lot of killing...
- This trope is extremely common in superhero comics to prevent the hero from becoming a killer. Often involves the superhero's imperiled secret identity. Some Spider-Man examples:
- The original Green Goblin (who was especially dangerous because he knew who Spidey was) getting impaled by his own glider in ASM #122. (He got better, later).
- The Jackal (Miles Warren) having a meltdown after being unmasked by Gwen Stacy's clone and ending up being killed (along with the Spider-Man clone) by his own bomb at the ending of the original Clone Saga in ASM #149. (It was not the last we saw of either).
- The burglar conveniently having a fatal heart-attack in ASM #200 moments after Spider-Man took off his mask and showed him he was the nephew of the guy he murdered in Amazing Fantasy #15.
- Carrion (Professor Warren's clone), who also inconveniently knew Spider-Man's secret, killed by his own Spider-Amoeba in Peter Parker the Spectacular Spider-Man #31.
- The Composite Superman, a Silver Age enemy of Superman and Batman, possessed all the powers of the Legion of Super-Heroes and knowledge of the heroes' secret identities. He defeated them and demanded that they give up being heroes, and they actually considered it(!), but the powers then faded away, leaving him without even the memories of ever having been a villain! (This actually happened twice!)
- The Marvel Universe gives us Thanos, who routinely comes dangerously close to complete universal domination, only to screw up in some fashion at the last moment and engineer his own defeat. This behavior is noted by both Vision and Adam Warlock in The Infinity Gauntlet, wherein after taking on almost everyone in the Marvel Universe, including Eternity himself, he decides to become a disembodied presence and leave his body sitting on his throne, allowing his alleged granddaughter to simply grab the titular Cosmic Keystone from his inert form with no resistance at all. Adam Warlock then talked Thanos into making a temporary Heel–Face Turn with a Hannibal Lecture wherein he accused Thanos of deliberately—albeit subconsciously—sabotaging himself and giving up the power he knows he has no right to wield.
- Mortadelo y Filemón: It's a rule in the comics that when a villain really tries to destroy the pair for real, he will fail miserably and get himself owned. A notable example is "El señor todoquisque" the bad guy is a man who can disguise himself and, in the first half of the album, humiliates our heroes in very painful ways. However, when he decides to take care of them himself and goes to the TIA, his plans brutally backfire on him, and, at the end, he goes insane.
- Disney Ducks Comic Universe: There's a story written by Don Rosa where the Beagle Boys are the main characters and decide to break into Scrooge McDuck's money bin once again after stealing the building's original architectural plans. They carry out the scheme while the building is closed at night, but they all gradually end up trapping themselves in various situations with the remaining Beagle Boys deciding to come back for them once they've successfully carried out the heist. The comic ends with the Beagle Boys discovered by a mightily surprised Scrooge and Grandpa Beagle hearing the cops talk about this from his jail cel and muttering that his grandsons can't even beat an inanimate building.
Films — Animated
- In The Boxtrolls, Archibald Snatcher's obsession with upward nobility and insistence on cheese-tasting despite his violent allergies causes him to explode into a cloud of nasty yellow mist.
- In Monster House, it's revealed that a circus performer named Constance died after she tried to attack kids egging her house only to accidentally fall triggering a cement mixer that buried her alive under the house's foundation. Thus, her soul became trapped in the house forever. You know, for kids.
- In Rio 2, Big Boss gets eaten whole by a giant serpent.
- In Scooby-Doo Meets the Boo Brothers, the Skull Ghost ends up trapping himself when he opens the safe holding the hidden jewels, burying himself under it while Scooby, Shaggy, and Scrappy stood back at gunpoint.
Films — Live-Action
- All of the Batman films since 1989 used this trope extensively, at least regarding named villains. Batman and Robin (and later Batgirl) never, ever kill. Their opponents are beaten by falling to their deaths trying to kill the heroes (Two Face, in two movies), killed by another villain (Schreck and The Penguin by Catwoman, Bane by a more heroic Catwoman) driven insane from overdosing on Phlebotinum (Riddler), and captured in Tailor Made Prisons (Mr. Freeze, Poison Ivy). The only one who dies (mostly) by Batman's hand is the Two Face from The Dark Knight, but in that case Batman was only trying to tackle him to stop him killing a child and he fell as a result. Stretched a bit in Batman Begins, where Batman refuses to deliver a killing blow to Ra's al Ghul but nonetheless leaves him to die as the derailed train on which they're riding crashes, the derailment having been caused by Jim Gordon under instruction from Batman.
- Used in all three Spider-Man Trilogy movies to remove the villain while technically allowing the main character to keep to his code against killing.
- The first Green Goblin is Hoist by His Own Petard (impaled by his glider as per the comics above, Dr. Octopus and the New Goblin die due to Redemption Equals Death, and Eddie Brock kills himself by diving into the Venom symbiote just as Spidey's about to incinerate it. It's lampshaded by Aunt May in the third entry after Peter thinks he's killed Sandman with water: "Spider-Man doesn't kill people!"
- The accidental but somewhat convenient death of the burglar in the first movie - removing as it does the threat of Spider-Man's identity being compromised right at the start of his crime-fighting career - can also be seen as a case of this.
- In the Marvel Cinematic Universe, fate conspires so that the heroes rarely kill their own big bads.
- In Iron Man 2, Ivan Vanko blows himself up after being defeated by Iron Man, though he could've been taken into custody or attempted an escape, mainly because he was confident in his success and had nothing else to live for.
- In Captain America: The First Avenger, the Red Skull accidentally destroys/teleports/somethings himself when he tries to handle the Tesseract.
- In Ella Enchanted, the Big Bad Sir Edgar defeats himself with the poisoned crown he planned on using to kill his nephew and heir by putting it on during his Motive Rant at the end of the movie.
- A common theme in the Indiana Jones films as its more or less the lust for power that does the villain in while Indy wises up and leaves well enough alone. It has been pointed out in some movie reviews that in three out of the four films, Indy could have stayed home and let the villains destroy themselves with no negative repercussions (aside from initially rescuing his father and Marcus in the third film).
- Raiders of the Lost Ark: Belloq and his Nazi cohort opened The Ark of the Covenant themselves and its powers then disintegrated them a very painful manner.
- Indiana Jones and the Last Crusade: Donovan drinks the wrong chalice (which he let Elsa Schneider, his assistant, choose) and rapidly ages to nothing. Shortly after, Elsa falls to her death in an abyss when she's concerned more about reaching the Holy Grail below her than saving herself.
- Indiana Jones and the Kingdom of the Crystal Skull, Colonel Spalko wanted the unlimited knowledge, and she got more than she bargained for when she bursts into flames.
- The villain Mitch Leary in In the Line of Fire refuses to take his nemesis Frank Horrigan's hand and plunges to his death instead, in an Ironic Echo of an earlier scene in which Leary saves Horrigan from dying the same way.
- In The Lost World: Jurassic Park, Peter Ludlow is eaten by a T.Rex after trying to steal it's baby to lure it into a trap so he could benefit financially from having real dinosaurs.
- In Maleficent, Stefan self-disposes by trying to kill Maleficent even though she said "it's over", and tried to walk away. Overlaps with Disney Villain Death.
- Taking the place of Vincent Crabbe from the book, Gregory Goyle is the one who casts Fiendfyre in Harry Potter and the Deathly Hallows: Part 2, and while trying to climb to safety, grabs a loose chair and falls into the fire. Although his only intent was to kill Ron, he essentially killed himself.
- In High Anxiety, Nurse Diesel accidentally falls off a high tower when she attempts to jump Dr. Thorndyke in a last ditch effort to kill him.
- In Teenage Mutant Ninja Turtles (1990), Shredder is done in when he rushes Splinter and falls into a garbage compactor after trying to kill him with a throwing knife when he was on the edge, with the turtle's much less heroic (though still good-hearted) ally Casey Jones flipping the switch. Of course he's Not Quite Dead and comes back for some more shredding in the sequel, and does himself in by turning into Super Shredder via the last vial of the ooze and causing an entire dock to collapse on him while trying to kill the Turtles.
- In The Satan Bug, Ainsley chooses to leap out of his own helicopter after Barrett gains the upper hand rather than tell Barrett where the missing flask of botulinus is.
- Just as in the book, in Where Eagles Dare turncoat British officer Colonel Turner opts to jump out of the plane at the end rather than face justice.
- In Casper, Carrigan's goal throughout the movie has been to take a "treasure" from the mansion, a goal she continues to pursue after coming back as a ghost. Finally, she does get her hands on the treasure, and she gloats that now that she has it, she has no unfinished business, she has everything—so against her will, she crosses over to the afterlife, as all ghosts must once their unfinished business is complete.
- In A Brother's Price the heroes have no scruples about killing women. However, to kill men would be considered abhorrent. Keifer, the husband of the princesses survives longer than he might have without this advantage, but eventually self-disposes by insisting that they attend an opera in a public opera house, which then explodes, with half of the royal family in it, including him. While the younger princesses grieve for their sisters, they are happy to be rid of him.
- In earlier The Dresden Files books, human villains have a tendency to kill each other, be hoist by their own petard or killed by side characters... so Harry doesn't have blood on his hands and The White Council doesn't get angry at him.
- In Stardust by Neil Gaiman, there are two major villains, who effectively and elegantly dispose of each other when the heroes aren't even around. In the film version, three out of the five villains die at each other's hands.
- Likewise, the climax for Robin Cook's Vector has the two villains polish each other off.
- In The Book of the Dun Cow, Cockatrice is impaled by Chauntecleer's battle spurs and mortally wounded. He lunges one last time for the rooster and finishes himself off in the process.
- Harry Potter and the Deathly Hallows:
- Wormtail is strangled by his own silver hand as punishment for showing Harry a small impulse of mercy when reminded that Harry saved his life. This does not happen in the film, and the closest that is implied to a death scene for him is that Dobby killed him, who is on the heroes' side.
- Vincent Crabbe casts Fiendfyre in an attempt to kill Harry, Ron, and Hermione, unleashes far too much flaming destruction than he beckoned for, and accidentally incinerates himself (along with one of Voldemort's Horcruxes).
- Voldemort himself. Harry explains him that the Elder Wand Voldemort uses is actually Harry's, due to a set of complicated magical rules concerning wand ownership. As a result of this, the Elder Wand will not kill Harry. Despite this explanation and the chance to repent, Voldemort still fires a killing curse at Harry, which reflects back towards him, finishing him once and for all.
- The Lensman series has a subversion in that it's deliberately engineered by one of the heroes. Nadreck's solution to the problem of a Boskonian base is to get all the Boskonians to kill themselves and/or each other over the course of a few minutes. He is ashamed about it, but it's because he had to personally intervene to kill three of them himself when the shooting was all over; he considers this to be sloppy work.
- In The Satan Bug by Alistair MacLean, Pierre Cavell gains the upper hand against Enzo Scarlatti aboard a helicopter that's in flight. After some discussion about the trial the villain will face, Scarlatti, rather than face British justice, opts to open the door and jump out to his death. Cavell doesn't try to stop him.
- Where Eagles Dare: the traitorous British officer Colonel Wyatt-Turner opts to leap out of an airplaine mid-flight rather than face the hangman, and, as in The Satan Bug, he heroes don't try to stop him.
- In The Dragon Heir by Cinda Williams Chima, the villain self-disposes by magically attacking someone who is not only immune to magic, but sucks magic out of wizards. This effect doesn't kill on itself, but does cause exhaustion, so the villain falls down, and there's a handy cliff nearby ...
- At the climax of Twilight Watch powerful magic users across the world are channelling energy into Anton as he faces the Big Bad. The Big Bad is shocked as Anton takes all this magic and turns it into a simple shield, protecting himself from all physical and magical influences. Anton inwardly notes that he can't let the Big Bad read his mind and understand the flaw that he as seen in the plan. The Big Bad then proceeds to teleport himself close enough to the International Space Station to be able to visually target a location to teleport directly on board, but as Anton realised, magic doesn't work in space.
- This was very common in the early seasons of Smallville with the krypto-freaks. If they didn't somehow lose their powers they inevitably met a messy end at their own hands.
- A major trope in Buffy the Vampire Slayer, particularly during the early seasons. Human villains tended to fall into pits of their own monsters while Buffy tried in vain to save them. See especially "The Pack" and "Go Fish".
- In the Angel episode "Supersymmetry". Fred attempts to kill the villain who, years earlier, had trapped her in Pylea, a demon Hell Dimension, by sending him through one of his own portals. When her boyfriend, Charles Gunn, intercedes, he explains that if she kills him in revenge she will never be the same. Gunn then snaps his neck and throws him into the portal, and they tell the rest of the heroes that this trope happened and he fell into his own portal.
- The Flash (2014): Trajectory, who has gained advanced speed powers thanks to a super drug called Velocity, ends up accidentally killing herself by overdosing on the drugs and running so fast that she disintegrates.
- Terrorists often martyr themselves in 24, most notably Habib Marwan, the Big Bad of Season 4.
- In the episode "Flashpoint" of Walker, Texas Ranger, two rouge Irish terrorists, a man and a woman, jump out a skyscraper window after sharing a kiss, choosing to become martyrs over life imprisonment.
- A Hercule Poirot sketch on That Mitchell and Webb Look had the detective calling the Summation Gathering and eventually pointing out that the perpetrator is the woman who, over the course of the scene, has inexplicably got sexier, started smoking and started speaking in an "evil voice". Ultimately she shoots herself rather than go to jail. "It is better zis way: some courts, zey do not accept ze evil voice as evidence."
- Justified likes to play with this trope. In the opening scene of the series, US Marshal Raylan Givens confronts Tommy Bucks, a Psycho for Hire who tortured and brutally murdered a man in front of Raylan. Raylan has no jurisdiction over the crime and no evidence to arrest Bucks for another crime so he instead told him to leave Miami in 24 hours "or else". Right before the time is up, Bucks pulls out his gun and is subsequently shot down by Raylan. Afterwards, Raylan wonders if he would have been capable of murdering Bucks if Bucks did not draw his weapon and made the shooting 'justified'. Throughout the series Raylan is faced with moral choices that resolve themselves because the bad guys kill themselves, each other or force him to act in clear self-defense. This culminates in the finale of season 4 where a mobster threatens Rayaln's family but is Genre Savvy enough not to 'self dispose' so Raylan gets a second mobster to kill the first mobster for him.
- Star Trek: Voyager: Being more convenient for the crew not to deal with her, the spy Seska dies from a console overload in "Basics".
- In Adventures in Odyssey Dr. Blackgaard, already near death due to infection by the virus he had hoped to threaten the world with, stays behind inside the Whit's End building as the bombs he planted there are activated.
- In Les Misérables, Javert's entire worldview is shattered when Valjean saves his life from the rebels. He decides he simply can't live in a world where criminals can be good people, and jumps off a bridge.
Javert: And does he know, that granting me my life today, this man has killed me even so?
- Spider-Man: Turn Off the Dark: During the Final Battle, the Green Goblin tries to spite Spider Man by dropping a piano from the top of the Empire State Building onto the bystanders below. However, since Spidey had webbed the Goblin to the piano earlier in the fight, he ends up dragged to his Disney Villain Death.
- The hijacker on The Great Movie Ride at Disney's Hollywood Studios ends up offing him/herself when he/she attempts to steal a cursed jewel, which gets him/her roasted into a skeleton.
- One of the evil minions in The Eighth Voyage of Sindbad at Universal's Islands of Adventure decides to just jump to his death when faced against both Sindbad and Amoura.

- Boomer and Buzzar commit suicide in a Disney Villain Death when they are defeated in Super Mario RPG and Paper Mario, respectively.
- In The Legend of Zelda: Majora's Mask, Garo Master blows himself up with a bomb to "die without leaving a corpse".
- In MOTHER 3, Porky seals himself in the Absolutely Safe Capsule with no escape, yet he is now ageless and cannot die and must remain for eternity. Fate Worse Than Death indeed. Also a "tragic" example with the Masked Man, whom the protagonist cannot even attack against, uses attacks that the Franklin Badge reflects to break Free.
- In Uncharted 3: Drake's Deception, Rameses, though wounded by Nate, shoots the window of an underwater portion of the ship, causing it to flood and drown him. Although Nate is able to escape.
- In Pokemon Heart Gold and Soul Silver, it was popularly believed that the unlockable encounter with Giovanni led him to commit suicide by jumping off a waterfall, due to the radio static in that scene sounding like a splash. This has been repeatedly refuted by Word of God, and disproven completely by Giovanni's appearance in Black 2 and White 2.
- In Mega Man Zero, Hidden Phantom, although not exactly a straight-out villain, detonates his own body when he fails to subdue Zero before he reaches Copy X. More startling is the fact Phantom is the only one of the Four Guardians to try a suicide attack on Zero, indicating he may be the most ruthless of them all combined.
- At the end of the first Golden Sun, Saturos and Menardi throw themselves into Venus Lighthouse rather than accept defeat by Isaac & Friends. Subverted with a vengeance (literally) in The Lost Age when it turns out they weren't exactly villains to begin with.
- Subverted and inverted in the ending of Super Meat Boy. Dr. Fetus seems to be killed by his own Dying Moment of Awesome, but then he pops up again, only to be crushed helpless by Bandage Girl.
- In Xenoblade, the plot begins as a revenge quest to kill robot "Metal Face," who has killed countless humans. But when the heroes discover that Metal Face is actually a human named Mumkhar piloting the robotic suit, they decide to let him go, despite having a chance to kill him, since the heroes decide that killing a human is always wrong. Mumkhar takes this opportunity to fire a blast at the heroes. But the blast misses and hits a spire that falls down and impales him and pins him to a falling platform, killing him.
- In Batman: Arkham City this is The Joker's fate, who decides to stab Batman rather than allow him to administer the cure for his illness. As the Joker lies dying from his own stupidity, Batman points out the absurdity of this, causing the Joker to admit that it's actually sorta funny.
- In Darkstalkers Lord Raptor ends up accidentally killing himself in his character ending by absorbing too much of Jedah's dark power, resulting in him blowing up.
- In Dante's Inferno, the Queen of Hell Beatrice, who was preparing to fight her former lover, ends up fainting after remembering her past identity thanks to Dante proving himself to her.
- In Mass Effect, if your Paragon or Renegade skill is high enough, you can convince Saren Arterius to kill himself because Sovereign is taking over his mind and it's not too late to help the hero. Though you have to fight his corpse once Sovereign assumes direct control. The same can also occur to The Illusive Man in the third game if you manage to make him have a Heel Realization.
- The third parasite in The Cat Lady forces the cat lady to play the piano before he kills her. Playing the piano is how she tells the neigborhood cats that she's ready to feed them, and they don't take kindly to him threatening her.
- In El Goonish Shive, Damien's Villainous Breakdown upon realizing Grace can match his power and he might not be a living god drives him to use his fire powers to immolate himself and Grace. If he is a god, he'll survive it; if he isn't, he doesn't want to.
- Subverted in The Order of the Stick, where Kubota cleverly surrenders right before Elan is going to kill him as revenge for Therkla's murder. Kubota realizes that he can probably raise sufficient reasonable doubt to get acquitted in a trial, and that Elan is too heroic to kill him in cold blood. Double Subverted, however, because Vaarsuvius isn't that heroic.
- In Schlock Mercenary Nov. 9, 2009 Schlock is trying to subdue some rioters who locked themselves in a storeroom in the ship, so he uses his plasma cannons to cut through the bulkhead. One of the rioters throws a hand grenade at the hole Schlock made, but it misses and bounces off the wall, before Schlock can even enter. This lands back on them and explodes. Turns out they were carrying antimatter which also explodes, incinerating all of them. Schlock didn't have to do anything. He thinks they did it to themselves on purpose, as he tells his crew-mate Elf, "They committed suicide when they saw me coming."
- In Atop the Fourth Wall, the King of Worms is killed when he accidentally scares himself to death upon looking into Linkara's mind.

- In King of the Hill, Debbie dies when she accidentally triggers her shotgun at herself while trying to climb into a dumpster in order to surprise attack Buck Strickland and his wife.
- Lampshaded and averted in Darkwing Duck in the episode where the Liquidator debuts, "Dry Hard". When Corrupt Corporate Executive Budd Flood falls into a pool of chemicals, Darkwing tries to reach him with a pole, only for the pole to melt. Darkwing is a little upset about it, but tries to hide it by telling Launchpad that "it saves a lot of time when the villain does himself in like that!" (Budd is not dead, however; the accident turns him into the Liquidator, making him far more of a threat than before.)
- Phineas and Ferb Doofenshmirtz evil schemes tend to backfire on him all the time, in fact there are times that when Perry is not around his own inventions get destroyed on their own.
