* ''{{Webcomic/Narbonic}}'':
** Subverted, where every self-respecting mad scientist expects their creations to at least attempt to destroy them. Helen repeatedly points this out to Artie: "[[http://www.webcomicsnation.com/users/narbonic/040505executor_You.jpg Let's face fact. As you are, you'd go on a pretty poor rampage.]]".
** Played straight when the subject Helen has been experimenting on for the entire run of the comic [[spoiler: dumps her even though she has fallen in love with him, and takes over another secret lair, which in another timeline leads to Helen's near-death and existence as nothing but a brain in a tank.]]
* ''Webcomic/{{Goblins}}'':
** The [[http://goblinscomic.com/d/20080110.html Fat Guard]] who tortured poor {{Fluff|yTheTerrible}}les.
** The demoness who used an ExactWords DealWithTheDevil to claim ownership of Dies' Horribly's soul falls foul of the terms of her own bargain.
* Referenced in ''Webcomic/QuestionableContent'' [[http://questionablecontent.net/view.php?comic=628 #628]].
* ''Webcomic/GirlGenius'':
** [[http://www.girlgeniusonline.com/comic.php?date=20030117 A bomb thrown at Gil]] is batted back to the thrower, killing him.
** '''[[http://www.girlgeniusonline.com/fun/twitter/twitter_othar_02.php Othar's twitter]]''': When Othar Tryggvassen builds a deathtrap he does a pretty damn good job of it. Some would call this irony. Everyone else, stupidity. Sigh.
** This is pretty much the defacto method of death for Sparks. Aside from being lynched by an angry mob for abusing the populace with their insane scientific creations, anyway.
* In ''EverydayHeroes'', while J.P. Wunsch is in prison, he tries to [[http://www.webcomicsnation.com/eddurd/everydayheroes/series.php?view=single&ID=156671 rebuild]] his power cuff that turns him into Wrecking Paul.
* In ''WebComic/EightBitTheater'', Thief gains his class change to Ninja by [[http://www.nuklearpower.com/2006/01/21/episode-651-thief-of-time/ stealing it from the future]]. ''Much'' later, after the other Light Warriors get their classes taken away, Thief avoids this. Then [[http://www.nuklearpower.com/2009/09/19/episode-1174-oh-thats-what/ his past self shows up...]]
* [[http://www.xkcd.com/730/ A somewhat meta example]] in ''{{Webcomic/xkcd}}''. (Check the AltText.) It's also a CallBack to [[http://xkcd.com/356/ this comic.]]
* In ''Webcomic/CuantaVida'', the BLU Medic is killed when he's (accidentally) injected with [[MercyKill the injection]] he meant to use on Blue Scout/Jeremy.
* ''Webcomic/TheOrderOfTheStick'':
** Xykon sends several goblins to their deaths simply to observe the effects of walking into Dorukon's Gate. They invariably explode, but Xykon is a ForTheEvulz kind of guy, and thinks it's funny. During the fight with the [=PCs=] he shatters Roy's ancestral sword, and Roy picks him up in a bout of UnstoppableRage and throws him into the gate himself. Of course, it takes more than the destruction of his body to permanently destroy a lich, but it does set his plans back months while he seeks out a new Gate.
** Tsukiko is a necromancer with [[ILoveTheDead a rather disturbing fondness for her undead creations]], believing that, since the undead are the antithesis of life and HumansAreBastards, the undead must be misunderstood, lovable souls. Redcloak demonstrates his own belief that the undead are nothing more than tools to suit a purpose by using a 'Command Undead' spell to force Tsukiko's thralls to devour her and each other.
** Tarquin wants Elan to be in command and in action, but his forces refuse to fight Tarquin's son, thus forcing Elan into a support role; once Haley points out that it subverts his father's plan, ''Elan'' is delighted with it.
-->'''Elan''': (''singing'') Rub, rub, rub, rub my father's face in my uselessness!
** In ''Start of Darkness'', while they may be the arguable good guys, the massacre of Redcloak's village was arguably what led to the conquest of Azure City and the near destruction of the Sapphire Guard.
** Lord Shojo willfully deceives the Sapphire Guard by using the Order of the Stick to investigate the other gates (Soon's Oath forbidding the paladins themselves from doing it), and fakes his senility to avoid being assassinated. While discussing his ruse with Roy and Belkar, [[ReasonableAuthorityFigure Hinjo]] and [[KnightTemplar Miko]] arrived. [[WordOfGod Word of the Giant]] says that Shojo's deceptions, while portrayed as a moral action, ended up [[spoiler: causing Miko to flip out and kill him.]]
* ''{{Girly}}'': Called out by Clone Sidekick Hammergirl, as she is smashed to death with her falling hammer to reveal a hollow center!
* In ''{{Juathuur}}'', the juathuur deserters with whom Meidar is fighting left the path in large part because the SecretTestOfCharacter she had for each of them left them disillusioned. One particular former juathuur, Rowasu, kills her in the end.
* ''Webcomic/NatureOfNaturesArt'': SV, why did you decide that harnessing the power of '''malice''' would be a good idea? Sure, it's a rather [[BlueAndOrangeMorality unorthodox]] definition of malice, but that doesn't change the fact that it ultimately killed you - or "[devoured] you as you [devoured] it", as you put it. At least you realised it ''at all''.
* ''{{Webcomic/Spacetrawler}}'':
** Yuri goes full cyborg, incorporating more and more weapons into her body. Martina decides that Yuri is going too far and needs to be restrained. To incapacitate Yuri, she uses a bomb that Yuri herself had commissioned from the Eebs.
** [[spoiler:The Eebs]] created the [[RestrainingBolt brain clamps]] that would eventually be used to cripple their psychic powers and rob them of free will. In fact, they were the ones who started brain-clamping each other in the first place; when outsiders decided to enslave them, all that was necessary was to kill the ''half-dozen'' of them who remained unclamped.
* ''{{Webcomic/Homestuck}}'':
** Equius's bodybuilding obsession leaves him strong enough that a rifle [[http://www.mspaintadventures.com/?s=6&p=005338 falls apart in his hands]][[note]]Top left corner of the room at the top of the stairs, after "hiding" as Nepeta (the catgirl; talk to her to take control).[[/note]]... a few strips later, Gamzee wounds him with a bow and arrow, then walks ''slowly'' across the room to garrote him.
** Vriska [[spoiler: stabs Tavros with his own lance]] after he tries to kill her, killing him.
** As the Thief of Light, Vriska has apparently complete ownership over [[LuckStat fortune]], with the ability to alter luck-based events to her whim. When she refuses to back down from going off to fight Jack, Terezi makes her a bet her ego could not refuse - a simple coin flip. Heads, she stays. Scratched heads, she ''goes''. The double entendre of the word was intentional and understood by both to be death. Vriska forces the coin to yield the scratched head, gambling that Terezi did not have the courage to go through with it. She was wrong in the [[spoiler:Alpha Timeline]], and dies in accordance with their agreement.
* In ''Webcomic/MitadakeSaga'', Kira [[spoiler: has their own name written into his Death Note by the very girl he betrayed and left for dead - in her own blood]]. This is realized far too late.
* ''Webcomic/TwentyFirstCenturyFox'' has a few incidences that have this trope:
** Subverted [[http://techfox.comicgenesis.com/d/20080707.html here:]] Col. Tora Scobee, a bionic wolf, plants a bomb in the office of his rival, Borzoi, who is a Russian Wolfhound. Borzoi sees the bomb ''just'' as Scobee is getting into his car, and Borzoi chucks the bomb at the exact moment Scobee is inside. The last scene with Scobee in a full-body cast and his boss, Stinky, berating him.
--->'''Stinky:''' Scobee, this rivalry with Borzoi has '''''got''''' to stop. We're running out of spare parts!
** Played straight when two tiger-girl Mooks learn too late about [[http://techfox.comicgenesis.com/d/20090119.html the direct way for sinking a ship.]]
* Petey in ''Webcomic/SchlockMercenary'' just loves to do this sort of poetic justice, to the point of turning it into a standard procedure.
** A government [[http://www.schlockmercenary.com/2005-12-11 explicitly responsible]] for defenses cuts some expenses on this part and he had to intervene?
--->'''Petey''': You must demonstrate the ability to defend the surface of this planet. A Frigate armed with light shields and a fully operational plasma lance has just entered orbit. All you need to do is shoot it down.\\
'''Petey''': In ten minutes it will be overhead, at which point it will destroy this building and any who remain inside.
** U.N.S. requests the extradition of mercenaries who blew up a TV company, pulled an insider job in process and planted fake evidence. After the local government itself [[spoiler:hired them to attack the company via special interest group as a sting operation and part of a social engineering program, also made money on this insider information, and planted fake evidence]]. The case is clear, so he's most eager to cooperate...
--->'''Petey''': but I expect that you will get quite a rise out of them when you explain to them that these proceedings will be made public as part of the extradition process.
** ...and since they didn't learn fast enough to drop it fully:
---> '''Detective Fitzsimmons''': These thugs might get away with blowing up buildings, but there is still the question of illegal [[SuperSoldier soldier boosts]].\\
'''Petey''': Question? There is no question at all. The human Toughs have illegal boosts, which they acquired via a fugitive U.N.S. researcher.\\
'''Petey''': Oh, wait... you mean the "does the U.N.S. want [[RevealingCoverUp the details of that technology released as part of these proceedings]]" question.
* CampaignComic ''Webcomic/OnePieceGrandLine3Point5'' sees Cory fall into this several times, due to his taking several Flaws he figured would never come up. For instance, he gave Zoro the [[UndyingLoyalty Loyalty]] flaw, thinking he was gaming the system since the ChaoticNeutral swordsman never answered to anyone. Then he agrees to join Luffy's crew.
* In the ''Film/AttackOfTheClones'' portion of ''Webcomic/DarthsAndDroids'', Pete is forced to run R2-D2 through the death trap maze he created when he was GM as punishment for putting the others through it.
* In ''Webcomic/{{Sinfest}}'', [[http://www.sinfest.net/archive_page.php?comicID=1964 Lil' Evil uses his slingshot to attack God. He fails to consider gravity.]]
* In ''Webcomic/BobAndGeorge'', in the tourney, Mouseman thinks he can obviously defeat Catman because the cat always gets caught in its own trap. His attempt to lure Catman into it means he gets caught.
* Subverted in ''Webcomic/VoldemortsChildren'', where it turns out that Zabini wasn't ''intending'' to survive the [[spoiler: Fiendfyre (s)he conjures when Draco and Luna attack]].
* Subverted in ''Webcomic/KevinAndKell''. Vin, plotting against Rudy, throws prey pheromones on him during a "blind stalk" event in which teams hunt in pitch black darkness, guided only by smell, in an attempt to make Rudy's teammates eat him by mistake. By the end, Rudy not only survives, but gets a trophy to take back, while Vin was supposedly eaten by Rudy's teammates, who were unable to see him. It turns out that he [[HeKnowsTooMuch stumbled on a Great Bird Conspiracy operation he shouldn't have seen]] and [[FakingTheDead they abducted him while faking his death]].
* ''Webcomic/TheWhiteboard'': A RulesLawyer badger who was using [[http://www.the-whiteboard.com/autotwb1684.html a rules interpretation depending on a technicality about what counts as a hit]] to make things difficult for others playing at Red's field gets some comeuppance in [[http://www.the-whiteboard.com/autotwb1688.html this]] and the following few strips. When the badger seeks to complain about the CurbStompBattle of everyone on the field against him, Jake points out that according to the same set of rules the badger was (mis)using, nothing says that the teams have to be the same size, complete with a LampshadeHanging in the last panel of [[http://www.the-whiteboard.com/autotwb1690.html this strip.]]
* In ch. 45 of ''Webcomic/GunnerkriggCourt'', as part of her latest malicious plan to torment her unwitting "owner", Hetty has Reynard help her secure a number of items, including lighter fluid and matches. [[spoiler:[[KillItWithFire Reynard later uses them to burn Hetty's physical body]] so he can attack and kill her etheric form.]]
