In Nadia: The Secret of Blue Water, Big Bad Gargoyle suffers one of these in a big way when he enters a space intended solely for Atlanteans and is promptly turned into salt, revealing that he, who has been fighting for years to subjugate the human race under Atlantean rule, is himself a human adopted by the Atlanteans.
Subverted in the manga, where the Senshi themselves killed the minor villains (Sailor Moon herself got a few too.)
In Black Lagoon, Chaka is rude, obnoxious, and such a Jerk Ass that even his Yakuza family dislike him. After he attempts to take over the family by selling Yukio, the rightful heir, into sexual slavery after raping her, he is beaten, had his hands cut off, and drowned - and his tormenters say he got off lightly.
Shishio Makoto of Rurouni Kenshin suffers a Karmic Death, succumbing to a fatal condition that does not allow him to fight for more than 15 minutes at a time without overheating (and in this case, causing his body fats and oils to catch fire), just as his opponent Kenshin is lying exhausted and helpless on the floor. This is made even more karmic due to his wealth of fire-based attacks, and the series implies that his death is almost literally karmic; "The man does not choose the age: the age chooses the man."
Fighting on a platform surrounded by fire-spewing smokestacks (did those do anything, by the way?) probably wasn't a very wise idea either.
Although it's not quite the same thing, Osamu Tezuka's Phoenix masterpiece is rife with examples of karmic retribution. Consider the one in Strange Beings / Life: A woman, raised by her evil father as a warrior, learns that her father is dying but might yet be saved by a mysterious nun who lives on a remote island. She travels to the island to kill the nun. After killing the nun, she finds she can't leave the island, and circumstances cause her to pretend to be the nun for some travelers. She finally works out that time is flowing backward, and not only is she the nun, but she can look forward to a day when she gets killed by her own hand. Which will of course continue the cycle indefinitely, unless she can work off her sins through healing those who come to visit the nun. In other words, this is Karmic Death, or dying through one's own actions, a little more directly than most, and with a delay of over ten years between act and payback. Also notable in that by the time of death, the woman had learned her lesson and was no longer a villain type in the slightest.
Standard way of tying up stories with murderers, con artists, etc. in Kurosagi Corpse Delivery Service if they're not caught by the police. Insurance salesman killed by an unlikely probability, cryopreservation scammer trapped in a glacier— whatever your sin, Narrative Causality has a death to suit.
In School Days, the main character is The Casanova who has spent 90% of the series playing with the hearts and interests of several girls, becoming more and more of a Jerkass as the story advances. In the end, though, a girl who is supposedly expecting his baby snaps violently after he suggests she should have an abortion, and stabs him with a knife.
That was only in the anime however. In the game's ending that was closest to that scene, she stabbed him because he decided to simply abandon her and go back to his old girlfriend. Of course, as he's crawling across the ground and bleeding to death, he becomes The Atoner and realizes the error of his ways, then dies.
In Narutaru, one of the main character's best friends is bullied to truly monstrous extents by the local Alpha Bitch Aki Honda and her Girl Posse. The peak of it is when Aki rapes the poor girl with a test tube. What does the victim do when she gets a shadow dragon? Well... she uses said dragon to kill all but one of them - and even the sole survivor gets her leg ripped off. Oh, and she kills other people too. And the one who gets the worst death of all is Aki herself, who gets the shadow dragon raping her with its clawed finger and then ripping her body in half. And then things go considerably From Bad to Worse. The fact that this is even considered Karmic Death at all speaks volumes on just how completely messed up the world of Narutaru is.
He's a lot less reserved in Dragonball, killing Old Piccolo by punching his way through his chest, and other choice actions.
Yeah, in Dragonball two Mooks were creepily hitting on Bulma (probably with intent to rape); Goku showed up and killed them. When Bulma felt sorry for them and said they were only doing their jobs, Goku just laughed it off. He was 12.
Some of them he did on purpose like when the remaining Red Ribbon Army soldiers ambush him he kills them because they are in his way he even vaporizes two of them with a point blank Kamehameha, and he was really pissed at Tambourine for murdering Krillen and taking pleasure in killing innocent people.
He stops killing his opponents starting with Piccolo Jr. who later becomes his ally.
Probably because he spent three years with Kami, the first civilized role model of his life. Gohan was only around long enough to teach some basic values that probably applied more to the jungle than civilization, Roshi explicitly taught him that if he encounters an evildoer it is his responsibility to decimate them, and after wiping out an entire army (at age 12) he travelled around the world for three years without guidance.
Keep in mind with the examples of the Red Ribbon Army, Goku did not know how to pull his punches, and from his perspective evil deeds make you an evil person. He actually explained his straightforward reasoning to Bulma (after he killed those Red Ribbon Army soldiers). If you survive, well at least you're not moving, so Goku would leave you alone. Basically, if you're a bad guy, Kami must have a good reason to keep you alive when facing Goku (possiblyfor morepunishment). Goku notably mellowed out when he was 18-19, with the years spending with Kami. After that, he couldn't stopsparingthe bad guys (Ironically, to his friend's surprise, even Bulma).
A sort of twisting of this trope comes with Frieza. It follows the trope at first, with Goku refusing to kill Frieza and Frieza lashing out at him behind his back, but the Karmic Death occurs when Goku turns around and destroys Frieza in his rage, no remorse. Though he doesn't actually die. He later returns as a cyborg, and goes to Earth to kill Goku's friends in vengeance. It is then where he meets his actual death, in the form of Trunks. A rather expanded Karmic Death.
Such a brutal departure from more merciful kills by Dragon Ball characters. Trunks slices Frieza in half, then proceeds to slice those halves into even tinier bits, and he blows him to ashes with a ki blast.
This trope actually fits Frieza more than one would be led to believe. Think about it. He does all he can to destroy the Saiyan race for fear that one day a Super Saiyan will emerge and destroy him. So what happens? He kills Krillin and threatens to kill an already defeated and injured Gohan, causing Goku to finally transform into a Super Saiyan before tearing Frieza a new hole. That's right. Frieza created the very being he spent such a long time trying to destroy.
Commander Red's end also qualifies in regard to this trope: Basically, he was the person who ordered the Red Ribbon Army around, so any atrocities that they committed were ultimately traced back to him (and it was heavily implied that several of the soldiers feared Red as failure or disobedience=death.). He either killed or arranged for the deaths of both innocent people and his own personnel just so he could gain the dragon balls. Did I mention that Red also lied to the personnel as to exactly what he was going to wish to the dragon balls? Well, when Black, after narrowly surviving inevitable doom both times (from falling and from being crushed to oblivion) overheard what Commander Red's true wish was (It's definitely not World Domination, or even conquest, period. His wish was probably the most trivial of wishes which was to get taller.), he was appalled by the desire, especially how said wish nearly resulted in the Red Ribbon Army's demise, especially after Goku's attack on the Red Ribbon Headquarters, and after Red not only ignored this, but even said that his soldiers are expendable, and even hinting that he'll kill Black due to outliving his usefulness, he himself is killed by Black by a gunshot to the head.
Nearly all of the ways that the Homunculi are killed are either clearly ironic or a reference to Dante (Alighieri, don't confuse with the character of the same name from the 2003 anime version) who made punishments that were more subtly or symbolically ironic.
The first Greed was impaled face down (as per Dante) then melted down for his most valuable part, Lust was incinerated (as per Dante), Gluttony was eaten alive, Envy pulled out his own heart out of self hatred rather than live as a Homunculus, Sloth died after expending all his energy in a long and grueling fight, atheistic Wrath was killed by the rageful but religious Scar who survived the genocidal war that Wrath instigated, Pride unsuccessfully tried to take over the body of an "inferior being" i.e a human and then was ultimately stripped of his power, the second Greed died performing a selfless act while saying that he'd gotten all he could ever want, and finally, Father, whose horrible deeds came about only because he wanted freedom and all the knowledge in the world, was dragged back into the darkness from whence he came.
In the 2003 anime adaptation, Dante is presumed eaten alive by the mindless monster she turned Gluttony into.
Also from the 2003 anime, Sloth, the Homunculus which could turn herself into water, was killed by being literally evaporated.
Which doesn't technically fall under the trope's definition, as it was a direct result of the hero's actions. Metaphorically appropriate, however.
Nena Trinity gets hit with it in Gundam 00, killed by Louise, the sole survivor of the family Nena had callously murdered a long time ago. Louise herself, who committed atrocities in order to get to the point of killing Nena, gets the INVERSION of this trope: she ends up so messed-up that she would rather die, but instead lives in the end and must continue to struggle as The Atoner.
Ali Al-Saachez dies at the hands of Lyle "Lockon Stratos" Dylandy, the twin younger brother of the original Lockon (Neil), whom he killed four years ago. The exact details of his death are even more ironic: his first on-screen kill was Michael Trinity, shot right through the heart with a lightning-fast quickdraw absolutely no one - including Michael himself - saw coming. When Lyle (somewhat less revenge-driven than his brother) tries to give Ali a Last-Second Chance, Ali taunts him over lowering his weapon and tries to quickdraw on him too... only for Lyle to out-quickdraw him and blow his brains out with a single headshot. And There Was Much Rejoicing among the audience...
Or V. V., after stooping to any possible low imaginable, including being the one behind the murder of Marianne and lying to Charles about it, and giving Lelouch hell throughout the series from afar, is finally defeated by Lelouch (with an assist from Cornelia). Now bleeding and crawling towards Charles, he hopes for the latter's help. However, noticing that V. V. has been acting behind his back once again, Charles declares he has had enough, and takes away his code, leaving the now once-immortal to die.
Shion Sonozaki in Higurashi no Naku Koro ni (more exactly, the Meakashi-hen arc), after killing most of the cast disguised as Mion, her twin sister, falls to her death when the air gun holster that Mion always wears snags on the wall while Shion's scaling a building.
It was more so a suicide in the sound novels. Played straight with Rina (every world and Teppei (at least three).
In Death Note, users of the titular notes have a nasty tendency to end up killed by one. Ryuk even states in the very first episode that he will write Light's name into his Death Note one day, which he does when Light is defeated in the very end of the series.
Especially considering all the evil that Yagami Light has done to the people around him.
Technically, it's not proven whether Mikami died by Death Note, but the rest follows true (indirectly, in Misa's case).
Part 2: Cars is granted immortality in every sense of the word; he uses his newfound evolution powers to transform himself into stone to avoid a volcanic eruption, but the force of the blast launches him into space, where he is unable to change back or stop himself from moving. He eventually shuts down mentally, now a hunk of stone travelling endlessly.
Part 3: Dio is killed thanks to Jotaro's time stop ability, which Dio had been using against others to intimidate and kill.
Part 4: Yoshikage Kira's good luck finally runs out as he is struck and killed by an ambulance which a bystander had called to help him. When he tries to drag the spirit of one of his murder victims to hell with him, he is stopped by a group of otherworldly hands...which is the body part what Kira had taken from his victims.
Part 5 Diavolo unintentionally helps Giornio get the Requiem arrow, which upgrades his stand into one that can negate any action taken by an opponent...an ability almost identical to Diavolo's own King Crimson stand, which can erase a section of time and allows limited precognitive abilities. When Diavolo is killed by the new stand, he is forced to experience death for eternity, unable to see when it's coming, each and every time.
Part 6: Pucci's own Whitesnake stand allowed Emporio to gain Weather Report's stand, allowing him to finally defeat Pucci and save the new universe.
Folken Lacour de Fanel in Vision of Escaflowne. After his Heel Face Turn, Folken tries to attack his ex-boss Dornkirk, but the sword he uses breaks in two and the tip injures Folken fatally by impaling him in the chest. It doesn't help that the Zaibach has a machine that actually useskarma and destiny as its fuel.
There's also a subversion here, as Folken went to battle fully knowing that his days were numbered due to all the experiments Dornkirk had perfomed on him through the years.
In Fushigi Yuugi, Suboshi tries to kill Tamahome and Miaka, but his own weapon rebounds and plunges through his chest while the ghosts of Tamahome's family hold him in place. Suboshi had brutally murdered the family earlier in the series, making this doubly karmic.
Gendo's death in End of Evangelion fits this: It's confirmed to be a hallucination, but what we see is that Eva-01, which has his dead wife Yui's soul in it, picks Gendo up and bites his head off. Yui was the reason he was trying to initiate Instrumentality, and why he treated others (especially their child, Shinji) like shit. Gendo is even said by Word Of God to have wanted this to happen:
"So, this is my retribution? I'm sorry, Shinji." * Crunch*
Played straight at the final showdown between Johan and Tenma in Monster, during which Tenma is presented with a choice of shooting the former or watching him kill a small boy, when Johan is instead shot down by the child's drunken, raving father who just happened to stumble upon the scene. Promptly subverted when the paramedics discover that Johan is still alive, and Tenma decides to try to save his life once again.
The last part can count as even worse than Karmic Death for Johan since by saving Johan's life once again, Tenma proves Johan utterly wrong.
Hokuto No Ken — Souther suffers this in the hands of Kenshiro as a retribution to his crimes against children and his brutal murder of Shuu, having him bear the tip of the pyramid with his injured knees and then killed in sight. Although Kenshiro uses a humane finisher to allow Souther to die without pain, it still counts as a Karmic Death.
Kurata meets his demise this way in Digimon Savers as the climax of a very well deserved Humiliation Conga. His final plan to destroy the Digimon sets off a chain reaction, triggering an energy blast that vaporizes him.
Combat Mecha Xabungle, the Big Bad Kashim King and his follower Biram Key who turn the series for the worse, are killed by having a huge missile dropped right at their faces.
A Cruel God Reigns: Greg is killed after getting into a car accident in the car that he raped Jeremy in.
Reverend Craig treated his only daughter, Rahne Sinclair, as scum even before she turned out to be a mutant with a wolf-shifting power. This ultimately led to a situation where he brainwashed her into ripping the wings off of one her friends, then tried to shoot her. Seeing him in front of the wings he'd mounted as a trophy made her brainwashing kick back in, and she promptly ate him alive.
Comic/film example: Spider-Man. Spidey, infuriated over his girlfriend's death/near-death (depending on which version you're reading/watching), has the Green Goblin on the ropes when the villain reveals that he is Spider-Man's friend's father. As the Green Goblin apologizes, he sets up his glider behind our hero. Spidey jumps out of the way at the last second and the blade on the glider's tip impales the Goblin, killing him. For now.
The Governor from The Walking Dead suffers one of these at the conclusion of the "Made to Suffer" arc. After the remainder of his troops have finally broken into the good guys' sanctuary, scattering them to the wind and killing over half of them, one of his soldiers, at his urging, shoots a fleeing survivor... the main characters' wife and infant daughter. Upon discovering the Governor made her kill a baby, she empties her shotgun into the back of his head. The entire squad of soldiers get Karmic Deaths as well, as they're implied to be overwhelmed by zombies a moment later.
Long-running newspaper comic Dick Tracy makes karmic deaths of villains one of its defining features. But as of late, the strip has become a surreal series of storylines that are basically long, Rube Goldberg-like marches to see what gruesome end awaits the villain of the story. To the point where Dick and crew will abandon police procedure and common sense (and occasionally, the laws of physics) to facilitate said karmic fate. As in the current storyline, where the Big Bad gets torn apart by his own attack dogs after losing his protective whistle; all the while, it never occurs to Dick or his crew to shoot the damn dogs until LONG after the villain is a literal dog's dinner.
In the final issue of Atomic Robo And the Dogs of War, the second half takes a time skip to the 70's when Robo finally finds Otto Skorzeny after looking for him since WWII. He goads Robo, claiming that he had personally killed Nikola Tesla, Robo's creator, and stolen his ideas. Robo takes a gun, aims it at him, and... points it away, and tells Skorzeny that he already knows he's dying of cancer, and instead of giving him a quick soldier's death, he'll leave Skorzeny to die alone and painfully from his cancer.
In the DC Comics miniseries "Final Crisis: Revelations", after Libra kills the Martian Manhunter by means of lighting him on fire to show the assorted villains in his Secret Society that he could make their wishes come true, The Spectre goes after the people who wished it to happen. He turns Dr. Light into a human candle and turns Effigy into a melted puddle of a man by boiling him alive. Sadly, it doesn't work for Libra, but The Spectre does kill all the other villains in the room who tried to stop him instead.
Said villains, the Hangmen, are also an example. Spectre hanged them.
Speaking of Final Crisis, in the mini-series Legion of Three Worlds a couple discovers Superboy-Prime after he arrives in the future and he vaporizes them in passing. What makes this a Karmic Death? In an earlier storyline, the same couple discovered an alien child, Last of His Kind, in their yard... and vaporized it, burying its remains in their farm.
In one Batman story, Batman finds and confronts the man who killed his parents, Joe Chill, but can't find any evidence against him. taking a risk, he confronts Chill and accuses him of murdering the Waynes, and reveals that he, Bruce Wayne, became Batman because of what happened. He then goes on to tell Chill that he will always be watching, waiting to collar Chill for good. Terrified, Chill runs to some fellow crooks and begs for their help, claiming that Batman is after him because he killed his parents. However, the crooks are furious that because of what Chill did, Batman came to be and ruined their schemes time and again. In hot-blooded rage they gun Chill down, but before they can get him to spill who Batman is, the 'man himself comes in.
Batman: Still with us, Chill? Chill: Not...for long! Funny...because I started you off as Batman, the boys...plugged me! Yeah...I guess you got me...after all! Ahhhh...(Dies)
In "Ultimate Iron Man", Howard Stark makes a point of preventing Tony from killing Loni (which is a little odd, since Tony has killed dozens of people by this point, but perhaps this is different since she's helpless and it would be cold-blooded murder rather than combat), only for Loni's son Obadiah to come do the deed himself. Countlessly averted in the same series, where Tony saves Obadiah from multiple near death experiences, to Obadiah's amazement. It's a case of Laser-Guided Karma too — Obadiah killed his mother because she was willing to leave him to die for her own gain. He also felt genuinely grateful to Tony for all of the times Tony saved his life despite everything Obadiah had done to Tony and his father.
In Greg Pak's "Planet Hulk", Hulk beats the tar out of the Red Emperor, but the baddie's actual demise comes at the hands of the rampaging Wildebots, after the Emperor habitually failed to do anything to mitigate the threat they posed to his citizens. The animated film adaptation of the story features a different, but equally ironic, end for the villain.
The Wildebots later rebuilt him and made him realize the scope of his crimes. He is now a cyborg shell of his former self trying to redeem himself while facing scorn and disbelief from his past victims — including his own daughter.
In one Star Wars comic, Mako Spince, an old smuggling friend of Han Solo's, sells him and his wife Leia out to bounty hunters hired by Hutts for the death of Jabba. They manage to escape, and later on in the series the same man sells them out to Imperial forces. Han retaliates by flying right next to Spince's flight control tower, causing it to become caught in the Star Destroyer's tractor beam. The Imperials, rather than cut the power, increase it, and the traffic control tower, with Spince cursing Han, is torn up and impales the SD, killing all of them.
Superboy Prime has many deaths to his name (even though Countdown to Final Crisis, when he destroyed multiple Earths and vaporized a pregnant woman, is non-canon his bodycount is still pretty high). He even beat his own girlfriend Laurie to death when he got back to his own universe after she rejected him because of his past actions. At the end of his Blackest Night tie-in, it's heavily implied that Black Lantern Laurie rips his heart out.
That's not what happens though. It's revealed that he didn't kill Laurie, he simply broke her arm, and the two do find some measure of happiness. Prime later goes on another rampage after accidentally being teleported away from his own dimension, and ends up being trapped in the Source Wall, seemingly forever.
Another Batman example ; in Batman #414, Bats is investigating the mysterious "Dumpster Killer", who leaves women's mutilated corpses in dumpsters (and it becomes personal when one of the people killed is a friend of Bruce Wayne). Several issues later, in #421, Batman discovers the killer is a pair of misogynist douchebags, Karl Branneck & Vito Procaccini, and vows to take them down. In the next issue, Branneck kills Vito because he views him as a liability; later, Batman arrests him and he goes to trial, but is set free because a bloody knife Batman found at his house was found illegally. After making sure Batman isn't around, Branneck then sets out to target another woman...who promptly slits his throat with a straight razor (and was revealed to be the sister of his second victim, who had been personally hounding him so he'd choose to kill her). Fittingly, the name of the last issue was "Just Deserts (sic)"
A third Batman example comes from the mini-series The Cult: having been freed from his imprisonment and recovering from his mental and physical trauma, Batman and the Jason Todd Robin storm into Gotham to take back Gotham from Deacon Blackfire, who has taken it over with his army of similarly kidnapped and broken army. Batman finally confronts Blackfire and proceeds to beat him within an inch of his life before stopping; he couldn't arrest him nor, even if he didn't have his code, kill him - they'd just make him a martyr. Instead, he leaves Blackfire, broken and beaten, in front of his followers who literally tear him apart because his broken and pathetic self spat in the face of everything he drilled into their heads.
Near the end of the Kree/Skrull War story arc in the Avengers comics, it turns out that the government agent who's been preaching hate against aliens in order to turn public opinion against Mar-Vel (and the Avengers by extension) is a Skrull. Rick Jones (with help from the Supreme Intelligence) remotely shuts down his powers in the middle of a speech, causing him to reveal his true form; the angry mob he was preaching to immediately attacks and beats him to death.
In Ace Combat The Equestrian War, Big Bad Red Cyclone is responsible for starting the whole conflict and for the most part of the story, he only issues orders, such as the scorching of Equestria. He becomes trapped inside his own creation by Zeakros after Rainbow Dash and Firefly destroy the fortress' core generator, starting a self-destruct countdown. He is consumed by the expanding explosions as Fortress Intimidation is collapsing.
PeterLudlow, the realBig Bad of Rise Of The Galeforces gets an EPIC one near the very end. He sets it up by apparently spending most of Episode 3 trying to capture the T-rex family that initially antagonizes the heroes as part of a tourist attraction (actually an excuse to publicly kill them along with all other non-human species). When he later drops all pretenses, he defends himself from the angry father rex by shooting him in the eye. This enrages both the fellow 'rex he was defending - actually a Scaled UpViolet - and Chomper's own babies to boot. The result: Ludlow gets every bone in his body broken for his trouble, and is devoured by the very baby 'rexes he had been working so hard to acquire.
The Evil Queen in Snow White and the Seven Dwarfs fell off a cliff after being struck by lightning while trying to push a rock onto the Seven Dwarfs. Not only did she fall to her death, but the rock falls on her. And for good measure, vultures eat her body.
Gaston of Beauty and the Beast fell off of the castle after one final attack on the Beast. (This coming after the Beast spared his life.)
Tarzan's Clayton fell off a tree while attacking Tarzan with a knife, and was strangled by vines despite Tarzan's attempt to warn him (also an Ironic Death after saying "Africa was made for me...!").
After his attempt to use his army of undead soldiers reanimated by the titular Black Cauldron is thwarted, the Horned King is sucked into the Cauldron himself (and horrifically stripped to the bone in the process).
In The Great Mouse Detective, Ratigan uses a hand-bell as a summons for his hungry cat to eat any mouse that displeases him. At the climax, Basil swipes the bell and rings it just before Big Ben chimes, shaking Ratigan off to his death.
At the end of Bambi, the hunter that supposedly killed the titular character's mother is actually implied to have been burned alive in his own forest fire.
Walt had at one point planned to show the guy's body, but after an animator cheekily asked "Well-done or medium rare?" shelved the idea as tasteless.
Toward the end of Treasure Planet, the villain Scroop is literally thrown out of an airlock and into outer space by the heroes as revenge for killing a character named Mr. Arrow (who was literally tossed into outer space by Scroop) earlier in the film.
In the climax of Wreck It Ralph, the villain pays the price for messing with the program...and dearly.
Slightly subverted in Tangled (2010). During the climax, Mother Gothel starts aging to death when the hero cuts Rapunzel's hair; however, it's Pascal, the chameleon, who actually sets up her fall out of the tower's window. As Gothel is backpedaling and covering her face, Pascal pulls the same hair that had been cut to create a trip wire near the window. Gothel then trips over it while wearing the very lace-up boots she had used to kick Pascal across the room moments earlier. She can't maintain her balance because of the heels and she falls to her death below.
Pascal's set up might not count as Goethel aged to dust before the impact.
Done figuratively in Cars. At the end of the movie, Chick Hicks wins the Piston Cup, but in doing so his Pride, Wrath, and Ambition have revealed him to be a poor sport to the rest of the world. His career dies a metaphoric — yet very karmic — death as a result.
A rare serious example was in Licence To Kill, in which Bond asked Sanchez, "Don't you want to know why?", showing him the silver lighter wedding gift that Bond had given to Leiter and his wife before Sanchez had her killed and Leiter maimed by a shark. Bond then set the oil-soaked Sanchez on fire with their wedding present.
In Ella Enchanted, after Edgar's treachery is revealed, he gives his villain's rant, and then proceeds to place the crown that he poisoned on his own head. He has a half-second to realize his mistake before the poison takes effect.
In The Black Hole, The movie's main villain is crushed to death by debris as the ship is drawn into the eponymous black hole (hypermass), as his souless, evil robotic bodyguard Maximillian simply leaves the room despite his repeated pleas.
In Boy Eats Girl, Nathan, having escaped death by hanging with the aid of a magic spell, must poetically die by hanging at the end; although....
In Masters of the Universe, He-Man finally destroyed Skeletor's source of power, his troops are beaten, etc. Because he's ''such a good guy'', he tells Skeletor that it's over, and He-Man turns his back to Skeletor. Skeletor replies, "...yes... for you!", pulls out a hidden sword and attempts to run He-Man through. He-Man dodges in the nick of time, and Skeletor falls down a handy bottomless pit.
The demise of the crime boss Komtuan in Ong Bak possibly epitomizes the concept of karmic death, as he is crushed under the falling head of a giant Buddha statue, which he was trying to remove and sell. You don't get much more karmic than that.
Carl, the villain of Ghost, dies after he swings a hanging hook at the hero, in a massively futile attempt to halt Patrick Swayze's ghostly offensive, smashes the window behind him, and ultimately winds up impaled on the very un-soft glass.
The B-Movie The Sadist goes to rather extreme lengths for this. Out of nowhere, the villain falls into an abandoned well which is quickly revealed to be inhabited by dozens of poisonous snakes.
In Killing Zoe, Eric fucks up the heist, murders numerous civilians, and takes glee in spreading his AIDS. As he's about to murder his childhood friend, his gun jams. French police show up seconds later. At least six cops empty entire magazines from their machine guns into him, causing him to dance for nearly half a minute as he's torn apart by bullets. His infected blood is sprayed all over the place.
Subverted in No Country for Old Men. Near the end of the movie, "ultimate badass" Anton Chigurh is leaving his last victim's house when he gets hit by a car. Despite this, he maliciously survives with an open arm fracture and some broken rips, and manages to escape the scene, and, although heavily injured, can walk into the proverbial sunset. The implication is of course that his Implacable Man status doesn't just come from pure skill, but also quite a bit from pure dumb luck.
In the film version of Sweeney Todd: The Demon Barber of Fleet Street, the deranged and abusive asylum owner Mr. Fogg is left to the care of his "children", who quickly turn upon him and tear him to pieces. It's much more poetic (if much less awesome) than the stage play, where Johanna shoots him.
And in both the film and stage versions, Sweeney Todd himself is killed by a minor character — a young boy Mrs. Lovett took in, who goes insane after discovering what the meat pies are really made of. And he's killed using the very same razor that Sweeney used to kill so many people.
And Mrs. Lovett is baked alive in the oven where she cooked her cannibalistic meat pies.
In Ip Man, the cruel Japanese Colonel Sato, who had shot Master Liu to death earlier for losing against Japanese fighters, eventually gets killed by a shot from his own gun after it is wrestled away from him.
This seems to be the preferred method of dispatching villains in The City of Lost Children. The Octopus kill each other — they're conjoined twins, despite the singular name — due to mind control by the ringmaster they used to try to kill Miette. Krank dies after his attempt to steal Miette's dreams goes wrong, and he sees himself as the children he abducts do — a nightmarish, arbitrarily cruel monster of a man. He wakes screaming from his dream, and the shock kills him. And the inventor, after going murderously insane and deciding to violently correct the problems he's set in motion... ties himself to Krank's oil ring and lashes explosives to his body. He recovers his senses too late, and the explosives are detonated by a seagull.
Push. Nick's final battle with Victor, The Dragon. He gets a chance to kill him but doesn't, for unknown reasons. Victor is killed seconds later by a Bleeder though.
The Shawshank Redemption 's Warden Norton has what can be considered a Karmic Death. Once Andy rats him out, we see a close-up of one of the Warden's wall decorations, it says "His Judgment Cometh, and that right soon." Moments later he shoots himself through the head rather than be arrested. Red later gives us the all-satisfying line; "I like to think the last thing that went through Norton's head, other than that bullet, was to wonder how the HELL Andy ever got the best of him."
In The Frighteners, the two main villains (one of which is already dead) are dragged into Hell by a giant worm. Awesome.
A voiceover at the end of Picnic at Hanging Rock tells us that Mrs. Appleyard dies while attempting to climb the rock.
Even more karmic in Joan Lindsay's novel: Mrs. Appleyard falls and smashes her skull open when she sees a horrific vision of a gruesomely disfigured Sara.
Also, Anakin Skywalker's transition to Darth Vader is marked by Palpatine using Force Lightning to make Mace Windu fall to his death, while Vader's return to the light side/being Anakin is marked by Vader sending Palpatine to fall to his death.
Even better: Palpatine was using Force Lightning to kill Luke, and Vader's act stops him.
In The Avengers (1998), Father and Mrs. Peel's clone were killed when their balloon exploded after it ran into the Wonderland Weather sign.
One of the most blatant and cringe-worthy uses of this trope occurs in The Postman, where near the end of the film, Kevin Costner's character has already defeated the villain, has the option to kill him, but refuses because he's just too damned nice. Naturally, the villain draws a hidden gun and is blown away by his former trusted lieutenant and his own stupidity.
The Ghost Rider movie. After taking the San Verganza contract, Blackheart dies after Ghost Rider uses the penance stare. It didn't work the first time because Blackheart had no soul, but now had one thousand corrupt souls.
In the first Spider-Man film, Peter discovers that Norman Osborn is the Green Goblin and hesitates. Osborn takes advantage of the momentary weakness to try and kill him, but Peter dodges the attack and Osborn ends up getting stabbed by his own glider.
In the film adaptation of Clive Cussler's Sahara, the villain responsible for contaminating much of Mali's drinking water with toxic waste appears to have slipped away from punishment, until it is implied that the CIA has secretly replaced his bottled water with the very same contaminated water.
This happens in the book too.
Raising Arizona: Leonard Smalls puts Hi in a bear hug to weaken him up before shooting him. Hi spends this time gripping at Smalls' jacket, where Smalls keeps his grenades. Smalls knocks Hi to the ground, pulls out his twin twin-barreled shotguns, and cocks all four triggers. Hi holds up his hand in a "have mercy" gesture. That's when Smalls notices the hand grenade pin around Hi's finger. You can figure out the rest.
Carl Showalter's death in Fargo could be seen as this.
Wade Gustafson's death even more so.
In Guy Ritchie's Sherlock Holmes (2009), Lord Blackwood dies by hanging (from a chain from the top of the unfinished Tower Bridge; of course he'd attempted to kill Holmes after Holmes had spared his life from almost certain death seconds before).
Furthermore, the plot hinges on him cheating death at the gallows and escaping his much-deserved execution for murder at the beginning. Guess Karma wasn't too thrilled at him for that...
The Book of Eli. Gary Oldman's character escapes with the book and a leg injury, only to learn that it's a Braille Bible and thus useless to him. He tries to get his blind concubine to translate, but she refuses also noting that he is feeling feverish and likely is suffering from a gangrene infection. With most of his men dead he witnesses the anarchy below and it is heavily implied his end comes from either the riots or his infection.
Almost the whole point of the British World War I horror movie Deathwatch 2002. Every character who aids in torturing the lone German prisoner dies in a suitably horrible fashion (suffice to say, one can become very creative when it comes to barbed wire). The only character to survive the movie (and even then it's fairly ambiguous) is Charlie (because he tried to help the prisoner). Other characters get killed in a more traditional sense of karmic death, for instance, the Upper Class Twit officer being murdered by a particularly disgruntled (possibly deranged) trooper.
In the 1959 Journey to the Center of the Earth film, Count Saknussem tries to mislead and kill the heroes, but is eventually caught and sentenced to death. However, no one wants to kill him, so they take him along. Sometime after they reach the center of the earth, however, Saknussem eats Gertrude, Hans's duck. Shortly afterward, he falls against a boulder and is killed when several heavy rocks fall upon him.
Though not technically the main villain, Dr. Worley from Return to Oz uses an electro therapy machine to damage his patients' minds, and he will then lock them in the cellar. He nearly does this to Dorothy, but the power goes out at the last second. Later, Ozma helps Dorothy escape, resulting in Dorothy getting back to the Land of Oz. While she is away, Dr. Worley's clinic is hit by lightning and burns to the ground. Everyone is rescued, but Dr. Worley runs back into the fire to rescue his machines...
This trope is pandemic in the Indiana Jones films. Three of the four movies end with the primary villain being undone by their own ambition when the artifact they've been searching for destroys them. Although not the best example of the trope in action, since in every movie Indy has few compunctions about killing bad guys left and right.
Hilariously subverted in Punisher: War Zone, in a scene where the cops are careful and diligent about arresting and restraining a captured mobster, only for the Punisher to unceremoniously execute him half a second later.
Aliens: Weyland-Yutani Project Developer Carter J. Burke. Essentially got killed by the hell he indirectly unleashed on the colonists on the LV-426 Hadley's Hope Colony.
Alien Resurrection: Dr. Wren subjected at least eight people to be victims to the facehuggers and have an alien embryo burst out of their chests. He dies by having a chestburster break its way through his own skull.
While he didn't die, Steele begins the movie Balto as the town hero but is rotten to the core inside while the hero of the film, Balto, is the town outcast with a heart of gold. At the end of the movie, due to Steele's refusal to let Balto have the glory that he craves for saving the town, Balto ends up the town hero with the girl Steele spent the whole movie trying to get while Steele's lies are revealed, resulting in him being a hated outcast by the town dogs. Further irony comes from the fact Steele would've gotten greater fame if he'd let Balto help him in the first place.
In Saw 3D, Mark Hoffman is captured by Dr. Lawrence Gordon and left to die as punishment for killing Jill Tuck. "Game over."
(Unintentionally?) inverted in the Korean movie The Last Day. In the final scenes, about everyone who displays some kind of altruism dies, often horribly, for having tried to save lives. Most of those who were only concerned with their own survival, well, survive. Family Unfriendly Aesop much?
The Mind Screw movie 11:14, displayed in Anachronic Order, features among the many characters a teenage girl who is sleeping with two different young men without their knowledge. She pretends to be pregnant and tells each of them that she needs $500 to get an abortion. In reality, she intends to take their money and leave with a third man. Near the end of the movie, she's speaking to this person on her cellphone when one of the two young men calls for her attention, telling her that he got the money. She immediately crosses the street, only to stop in the middle of it to answer a call on her phone. Moments later, she's hit and killed by a speeding van filled with several of the film's other protagonists.
Speaking of the aforementioned Patrick Swayze, in his other classic, Road House, the evil BradWesley basically runs the town the movie is set in, forcing the local businessmen to pay him and trashing their shops if they refuse. In the final showdown with Dalton, it's not Swayze who kills him (as the latter did, graphically, to his Dragon Jimmy), but the aforementioned business owners, filling him with enough lead to take down a bear. Can also overlap with The Dog Bites Back or The Dog Shot First.
Sebastian Shaw/Dr. Klaus Schmidt in X-Men: First Class ends up being killed via Magneto telekinetically pushing the very same concentration camp-coin through his head and out that Shaw/Schmidt attempted to have Magneto move under the threat, and action, of murdering his mother back in 1944.
At the end of the dark comedy Miss Nobody, the Villain Protagonist lampshades this after realizing she's just taken a fatal dose of the poisoned water she had intended to use earlier on a colleague whom she'd suspected of being the person blackmailing her over murdering her way up the corporate ladder. She had poisoned one of the jugs in his personal supply, but never got around to disposing of it after the blackmailer turned out to be someone else. So in the end, when the jug in the water cooler in the office which she has as a result of her murders runs out and her assistant raids the colleague's supply for a replacement, he unknowingly selects the poisoned jug.
In The Assassination Of Jesse James, Wood Hite, a violent bully who threatens and insults Bob, laughs off His threats of a bullet in the head. Later He is shot in the head by Bob.
In Who Framed Roger Rabbit, Judge Doom is killed by the same 'Dip' that he is using to kill all the other cartoons. While Eddie Valiant has no qualms about killing the guy responsible for the death of his brother, the death that Doom suffers is a total accident that would have never happened if he had not invented 'dip' to begin with, nor if he had sidestepped the punching glove thrown at him which accidentally hit the 'dip' release valve which subsequently melted Doom.
Dylan Gould's fate in Transformers: Dark Of The Moon. He reactivates the Control Pillar of the Decepticons' Space Bridge —- despite Sam Witwicky trying to reason with him —- in order to bring Cybertron near Earth (he was promised that he would be spared after the rest of humanity was enslaved, and also possibly be given the role of humanity's "CEO"). Later on, Sam hits him with a metal bar, causing him to lose his balance. He eventually collides with the Pillar's energy beam, and is ultimately electrocuted to death, all the while screaming in pain.
Earlier, Sentinel Prime wounds Ironhide and then executes him point blank despite his plea for him not to. At the end, a wounded Sentinel is excuted point blank by Optimus Prime despite his plea for him not to.
In Machete, Senator MacLaughlin is a racist bastard who encourages vigilantes to kill illegal immigrants and plans to build an electric fence on the U.S./Mexico border.

Wounded, he staggers into an electric fence.

In The Catastrophe Of The Emerald Queen, King James is thrown off the battlements of Alegria castle by Mordalayn, to plummet into the woods a mile below. This was after murdering Leppard in a similar manner earlier in the book (dropping him into the Abyss room). Also Susan Veer sets a magical trap for Queen Sophie that she herself falls into. As she was a former Queen of Alegria the trap works equally well on her, despite not activating when Jared Miller stood directly on top of it moments previously. Finally Rancidrain, who is killed by a rainbow blade. A similar weapon to the one he used in his failed assassination attempt on the Emerald Queen.
Vincent Crabbe uses a powerful fire-spreading curse on the heroes that he himself can't control. He's the only one who gets killed by it.
The villains in the NUMA Series (the National Underwater and Marine Agency) of books written by Clive Cussler tend to die this way. The person who wanted immortality and nearly flooded the oceans with a very hard to kill Gorgonweed ended up killing herself by taking the potion meant to make her immortal because someone she had killed had messed with it making sure that anyone that drank all three of the shots needed for immortality would die from it. One person who wanted to destroy the world's fish trade with mutant fish was eaten by his own creations. A third person wanted to control the world's water and ended up dying by drowning, but the place where she was ended up blowing up so that may have killed her instead. A fourth whose improper disposal of waste was poisoning the local water tables, causing madness in those who drink the water, is tricked into drinking that water which has been secretly bottled and brought to him.

Bertha Mason's death in Jane Eyre by fire is very karmic since she started it in the first place and Mr. Rochester went back in to get her as well.
Similarly, we have Jane's cousin John who had always bullied her and gotten away with it many times. Even when he was an adult, his mother helped him twice get out of jail, paying off his debts, and he still returned to his ways. For the third time, his mother finally refused to help him and it was suspected he committed suicide to escape his debts.

Near the end of George Eliot's Daniel Deronda, the appalling Mr. Grandcourt finally meets his end when he falls off a boat and, unable to swim, asks his wife to throw him a rope. She hesitates just a moment too long...
Ellis Peters manages to wrap up a judicial duel with a Karmic Death in One Corpse Too Many. Hugh dropped his sword after disarming Adam, choosing to continue the fight dagger-against-dagger. When Adam went for Hugh's sword, Hugh tackled him. In the ensuing wrestling match, Adam rolled onto his own dagger and died.
In The Raven in the Foregate, the new priest lacks the critical virtues of charity and humility. He pronounces a naďve penitent irredeemable and refuses her absolution, and she drowns herself in the millpond. Later, he slips on a patch of ice near the same millpond, hits his head on a stump as he falls, and goes into the water unconscious. The one person who saw it happen doesn't feel any compunction about not helping him—extra points for irony because he viewed the Holier Than Thou priest's fate as divine judgment—the measure the priest gave was the measure he received, just as Jesus said.
Made even better by the fact that Garion is horrified by this sudden use of magic and watching someone burn so he decides to put out the fire. However, his aunt tell him Chamdar killed his family so he makes the fire HOTTER and burns him to ash.

Instead of saving his life the minion pushes him further into the ocean yelling the lines of praise he was forced to say every day, but this time inserting all the titles that Ungatt had despised and previously banned.
In the Dale Brown novel Plan of Attack, the Jerkass General Gary Houser, who had obstructed Patrick McLanahan and steadfastly denied the possibility of a Russian attack on the American mainland, dies when he is caught in the attack.
In The Sword Of Truth karma appears to be squarely on Richard's side, since practically everyone who disagrees with him dies unpleasantly. This may be because he or someone who works for him killed them, but if they don't then fate will see to it for them.
A regular occurrence in the Florida Roadkill novels. The most notable example being an insurance claims worker whose job it is to deny medical coverage, especially if said coverage is an official part of the claimant's policy. He gets shot and taken to the emergency room. The calls to his insurance company (the one he works at) get routed to his desk, which, since he is at the hospital instead of at work, he can't answer. So he is denied coverage, the bullet remains in his body, and he dies of lead poisoning.
Invidia, of Codex Alera is pretty much a poster child for Chronic Backstabbing Disorder. So much so that the Big Bad can't even bring herself to be angry at her sudden but inevitable betrayal because that's what Invidia does. This gives it a significant amount of irony when her death results from being stabbed from behind.
The Red King from The Dresden Files prepares a ritual to target the Dresden bloodline by harnessing the lifeforce from hundreds of human sacrifices. Unfortunately for him, because all red vampires share his blood, they are as vulnerable to the curse as Harry Dresden is. As a result, when Harry kills the youngest Red Vampire on the altar, the Red King and his whole Court are destroyed by the energy of all the hundreds of people they murdered.
In A Game of Thrones Viserys Targaryen marries off his sister Danaerys to the Dothraki warlord Khal Drogo in return for the latter's assistance in regaining the throne of the Seven Kingdoms. When he loses his patience, he ignores his adviser's comment that Drogo will offer assistance when he is good and ready, gets drunk, and publicly insults Drogo, Danaerys, and the entire Dothraki people, and demands Drogo gives him the crown he "paid" for with his sister. Drogo agrees to give Viserys a crown, melts down the gold from his belt, and "crowns" Viserys by pouring the pot of molten gold onto Viserys' head. This kills him.
In the first book, Janos Slynt takes special glee in pushing Ned Stark onto the block during his execution. Later, during court, Ned's daughter Sansa sees him enjoying his new position and wishes that some hero would kill him, but thinks that there are no heroes. Janos is eventually knocked down a peg and forced to join the Night's Watch. Four books and three years later, Jon Snow, Ned's bastard, Lord Commander of the Night's Watch, is forced to deal with Janos' insubordination. He decides to execute Janos and beheads him personally.

The detective then lays a penny on the opposite end of the room and leaves knowing The Gentleman will crawl for it.
Diogenes Pendergast from the Agent Pendergast novels spends two books trying to ruin his brother's life by getting him arrested and destroying his loved ones while he's set up for their murders, use the same device that robbed him of his own sanity on hundreds of people, and additionally trying to drive his brother's ward Constance to suicide first by seducing her and then revealing the truth behind her extended life in hopes the despair will crush her. This last tactic harshly proceeds to bite him back in the ass. Constance instead becomes so rage-driven at the way she was used that she winds up chasing him halfway across the world all the way to his remote home, every time he attempts to kill her she completely outsmarts him, and it all culminates with her causing him to fall down a volcano. He could have avoided all the trouble that inevitably lead up to his death and got away scot free after his "drive innocent people mad" failed if he hadn't have been such a cocky bastard and not tried to eff with her mind.
In Caro King's Shadoiw Spell, Strood, while trying to kill the heroes, accidently triggers the Curse Escape Clause of his Complete Immortality, causing all his previous "deaths" to catch up with him. His end is rather gruesome.
And shortly before that Strood subjects Ava Vespilio, the most evil of the Seven Sorcerers, who also is responcible for making Strood what he is now, to a Fate Worse Than Death, by killing his current Host, then throwing his Heart Drive Ring into a literally Bottomless Pit, making sure he can never possess a human again and will remain locked in the ring forever
Earlier, Mrs Dunvice, a brutal, remorseless werewolf in Strood's employ, is killed by the Skinkin which she was transporting for killing Nin
The Saint: Simon Templar made this a regular part of his repertoire as he matured in the stories. In "The Man from St. Louis", he manipulates a nastily ambitious punk gangster into murdering an even nastier Dirty Coward with Chief Inspector Teal as a witness; in "The Million Pound Day" he boomerangs a villain's murder attempt back onto the bad guy using a kid's toy; and in "The Death Penalty" he "deliberately and with malice aforethought" (his own words) visits the title punishment on a villain who under English law did not deserve it... but under The Saint's law, well....
Annie Wilkes from Misery watches the novel she wanted to read more than anything in the world get burnt, is forced to swallow it by her most favorite writer, who also beats her to death with the typewriter he used to write it. This death would be so sad... if it wasn't, well, Annie Wilkes.
All the characters who bullied Carrie get killed by her power, that they activated by making her so enraged. Special mention goes to Chris Hargensen and Billy Nolan (who are killed when Carrie takes control of the vehicle Billy tries to use to run her down), as well as Margaret White (in the movie, Carrie actually crucifies her fanatically religious mother).
Patrick Hockstetter from It gets killed by leeches growing in the fridge he used to kill animals. Also, leeches are the only thing he truly fears.

In Babylon 5, Lord Antono Refa, a racist Centauri noble, responsible for the bombing of the Narn homeworld with Weapons of Mass Destruction and the mastermind of death camps and genetic cleansing programs, is handed over to a mob of Narn insurgents led by G'Kar and beaten to death.
All to the tune of "And the Rock Cried Out, No Hiding Place".
In the second-season Buffy the Vampire Slayer episode "Go Fish", the coach who has been dosing the swim team with steroids that are turning them into Gill Monsters. He attempts to have them gang rape Buffy, however when she escapes he is devoured by his own creations — convenient, given Buffy's reluctance to kill normal humans.
Mentioned but avoided in the finale of Season 5, where Giles points out that since Buffy is a hero, she could never kill in cold blood, but he is not a hero, and proceeds to suffocate the Big Bad, while she is trapped inside her mortal and innocent shell.
Hilariously done in the Doctor Who spoof "The Curse of Fatal Death", where the Master falls down a pit into a vast and disgusting sewer network. Three times. He doesn't exactly die, but it's still pretty bad.
Numerous Doctor Who villains are finished off by this trope, most likely due to the Doctor being a Technical Pacifist. Notable examples include Davros killed by his newly-created Daleks in Genesis of the Daleks (extra points for Davros pleading to his creations in the same way that the Doctor was pleading to Davros earlier), and the Master killed by his physically and mentally abused wife in "Last of the Time Lords".
John Lumic, creator of the Alternate Universe Cybermen clearly didn't anticipate that they would turn against him. While he doesn't die, he gets to live out a Fate Worse Than Death by being Cyber converted.
Subverted in Stargate Atlantis episode, "The Prodigal." At the climax of the episode, the half-Wraith Big Bad Michael is hanging by his fingers from a very high point on Atlantis. Teyla kicks his hands loose and he falls to his death. He had threatened her son and the entire city with the self-destruct.
Although many victims suffer karmic deaths, a particular favourite was in "Ending Happy" where the abusive bouncer Lorenzo "Happy" Morales survived being hit over the head with a club, poisoned (twice) and shot (all arguably deserved) - but ultimately died from falling off the chair (and into a swimming pool) that he had failed to fix.
Another episode dealt with an investigation of the death of a body builder. As the case developed, it was discovered that the body builder was using steroids and had murdered a woman he had slept with the night before. Ultimately, they found out that the bullet from the gun he used to kill her traveled into a wall and just happened to lodge itself under a leaky pipe. Over time, mold started to grow off of the water and residue blood from the bullet and eventually infested the house. Because of long term steroid abuse, the killer's immune system had weakened to the point where his body couldn't fight off the mold spores and he died of fungal infection. The characters even remarked at the end of the episode that this was a case of poetic justice.
The man who killed the HIV-positive porn star in the snuff film, only to become infected with her HIV. Lampshaded by Catherine and Sara who note that "You killed her. I guess she killed you back."
Bob Dunn at the beginning of "Midnight". Spends his time cheating on his girlfriend at local nightclubs. But then he picks up the wrong girl and ends up getting his cerebrospinal fluid sucked from a chewed-up hole in what remained of his neck.
Phil on LOSTpunched Juliet in an attempt to make Sawyer talk during an interrogation. Later, as all hell breaks lose during an electromagnetic incident, he gets impaled by a flying metal bar.
Several in all seasons of Primeval, the most notable pair being Season 3, where Christine gets chomped by a future predator after getting into a pissing match with Helen over who is the bigger Jerk Ass, and Helen herself finds the punishment for trying to Ret Gone humanity is death by Dromaeosaurus.
In the Merlin episode "Lancelot and Guinevere", Hengist is eaten alive by his own pet monster after the heroes escape. However, this is unusual for the series - most of the villains are killed a little more directly.
In the third season The Man From UNCLE episode "The It's All Greek to Me Affair", the estranged husband of the innocent-of-the-week is a convicted criminal who's escaped from prison, and who spends most of the episode threatening to kill his estranged wife's meek, milquetoast schoolteacher boyfriend. In the climactic fight scene, the estranged husband (who is fighting with his estranged wife's boyfriend) winds up accidentally stabbed to death by the THRUSH Central representative to whom he had hoped to sell a valuable U.N.C.L.E. code he'd stolen earlier in the episode.
The episode "Paradise" had a serial killer (played by Wil Wheaton) that would kill couples and then stage their bodies in cars at blind intersections so that they would get hit by tractor trailers and have the deaths blamed on an accident. When the team finally catches up with said killer, he runs away, only to get hit by a tractor trailer. Wesley got "Crushed".
In another episode, a hitman manages to elude capture by the BAU (and probably would have walked anyway, since they had no hard evidence against him). In the last scene, he is shot to death by the protege of a mobster he killed for trying to rat him out earlier in the episode.
Many episodes of Criminal Minds, if they're not portraying the criminal as The Woobie or as an Everyman with issues, but rather as a completely demonic killing machine, end with one of these. Usually a member of the team will point a gun at them and give them a Reason You Suck Speech, then the guy will pull a gun or other weapon and be shot on sight, dying instantly. When this trope is subverted and the guy actually lives, it's often even more satisfying.
The titular serial killer of Dexter is a walking instrument of Karmic Death, but he usually makes sure the victims really get the karma. When he's got a drunk driver who gets out of convictions by feigning regret on his table, he plays the video of his last victim that was played at his trial. When he's working on a guy who breaks legs for a bookkeeper to pay off his gambling debts, he uses a room with disused casino equipment. And in the pilot, he forces a pedophilic serial killer to look at the bodies of his victims before going to work.
In the episode "Tribunal", an elderly, but unrepentant and still evil Nazi is brought back into the past and stranded in the concentration camp where he used to work. His past self casually executes him, not realizing who he was, and dismissing the corpse as "Just another worthless Jew".
In "The Vaccine", the Jerk AssSocial Darwinists force the nurse main character to mix up the titular vaccine for them at gunpoint, and even after they promise to save one dose for the little boy, they take it and give it to one of their own when the nurse's back is turned. They then go into anaphylactic shock, because they were already exposed and immune to the virus; the vaccine itself killed them and they inadvertently saved the lives of more sympathetic characters.
In "Deja Vu", a character suffers a Karmic Fate Worse Than Death; the general who secretly tried to weaponize a teleportation experiment ends up trapped in an endless loop of the second before his death when the experiment goes awry.
Burn Notice does this a lot. It's rare that Michael actually kills anyone directly, despite his colleagues urging him to do so on many occasions. He often leaves the bad guys to be dispatched by angry fellow bad guys after he's done sabotaging their plans.
Teen Wolf: It was implied that Gerard might die after his defeat in season two. His master plan you ask ? To cure his cancer by becoming a werewolf. Only after Scott tampers with his medicine, does Gerard's body rejects the werewolf bite, and he starts violently oozing black goo. Of course this is just an implication, so we are still gonna have to wait for season three.
The X-Files episode "Aubrey" had a former serial killer die at the hands of his estranged grand-daughter who was channeling his "genetic memory" and had essentially become him.
Charlie Harper in Two and a Half Men was a frequent womanizer who cheats on various ladies. According to Ashton Kutcher, the reason the character died was because he went to Paris, cheated on a woman there, and she decided to make sure he paid for it by pushing him into a bus.
In Medium a suspect has killed his wife and staged her death to make it look like she fell of a boat, Allison had a dream on how he really did it, as he killed her up in a mountain and chopped her hand off. When the police and her father discovered her remains, the father brought him in the woods and killed him the same manner the suspect killed his daughter.
Nikita: In the season 2 finale, series-long Big BadPercy is finally killed by Nikita just as he was on the verge of becoming a Karma Houdini. (Un)fortunately, he chose that exact moment to shift into a Smug Snake, and rather than walking away tries one last time to kill her, which ends up resulting in him being dropped down a missile silo. For bonus points, he ends up falling smack into the prison cell he spent the first half of the season locked up in.
Earlier in the season, there's the former Division scientist who was turning people into Manchurian Agents, and ends up killed by one.
In Spartacus: Blood and Sand, Ashur rapes Naevia and later arranges for her to be sold as a Sex Slave; all of which was simply for him to get revenge on Crixus (who was in love with Naevia). In Spartacus: Vengeance, Naevia and Ashur face off in a sword fight, culminating with her castrating and beheading him.
Lampshaded, though done in a way that would be Redemption Equals Death interestingly, in the Season 2 Finale of Once Upon A Time. Regina was going to use a device to destroy Storybrook and kill everyone, while using magic beans (which she stole from the heroes) to safely transport herself and Henry to the Enchanted Forest. Other villains capture and torture her, steal both the beans and the device, and plan on using to it to kill everyone including her. She then teams up with the heroes, plans on slowing the device down which will kill her, but will give everyone else enough time to steal the beans back and escape. She explains that all of this is ultimately her fault, so it is only fitting that she die trying to stop it. It winds up being Redemption Earns Life instead.
The vocaloid songs series The Seven Deadly Sins by mothy has plenty of this:
In Venomania, the duke is killed by a man dressed like a woman.
In Judgement, Marlon is sent to Hell with the exact same words he gave criminals.
In Princess Sleep-Bringer, Margarita commits suicide by drinking the poison she had given to everyone.
Riliane and Kayo don't die but Riliane loses her brother and it is essentially her fault. As for miss Sudou, well, see above... but also subverted, because now her body isn't even her own again.
The Terran Empire setting for Star Hero isn't a no-kill setting, but manages to sneak this in anyway. One of the later Emperors spent a good chunk of his reign giving people a reason to want him dead. He knows this, so among other precautions his bedroom is heavily armored and has a voiceprint lock on the only door. He also changes the door code daily, to keep assassins from using a recording to get in.
In 2663 he forgot the code overnight and could not get out of his bedroom. His guardian robots refused to allow anyone to approach the door with drills or cutting torches, and the Emperor died of thirst and starvation in his own room.
In Vampire: The Masquerade - Bloodlines, the entire game has your Player Character running around Los Angeles searching for a Sarcophagus that supposedly contains an ancient and unbelievably powerful vampire. This is done on the orders of Prince LaCroix, who desires to diablerize the slumbering Ancient and effectively nick all its awesome, god-like powers. In the end, it turns out that the sarcophagus he had lied, cheated, back-stabbed and manipulated to get does not contain an Ancient vampire, but half a ton of C4. Your imagination can probably draw an accurate picture of what happens next.
In Fallout 2, a teenage scientist, Myron, invents and spreads Jet, a very addictive and dangerous drugs that ruins many lives and absolutely destroys the economies of several communities (such as The Den and Redding). Said drug makes him and the Mordino crime family a fortune and establishes him as the wealthiest drug baron in the land. About a year after the defeat of the Enclave, he meets his demise in The Den at the hands of... a crazed Jet addict.
The Big Bad of Fallout New Vegas, Caesar, is the leader of a slavery-based, incredibly cruel, militaristic, and genocidal empire that invades the Mojave Wasteland. The empire, Caesar's Legion, automatically gives death or enslavement to numerous sections of the population: women, the physically handicapped, the ghouls, super mutants, the mentally handicapped, intellectuals, etc. but they especially look down on the sick for being took weak to live. As a result, Caesar banned all medical technology in his empire to let the sick die. However, it's later revealed that Caesar himself is an old, sick man with a brain tumor. Therefore, if the player doesn't kill him first, he'll eventually die of the tumor, being by his own logic took weak to live. Not that he didn't try using modern medical technology, mind you.
Arguably, you can give the whole of Caesar'sLegion a Karmic Death if your Courier is female. By the end of the game, you can potentially assassinate Caesar, kill Lanius, slaughter the head of their intelligence operation and all of his bodyguards, possibly kill the intelligence head's replacement, wipe out their outpost at Cottonwood Cove, take out a small slaver camp, destroy various patrols, lead the NCR to re-take the Legion-controlled town of Nelson, thwart an attack on Bitter Springs, root out a Legion spy at McCarran, destroy both of their allies in the Mojave (Fiends and Omertas), sever their alliance with the Great Khans, arrange for an army of killbots hidden in a bunker under their main base to awaken on your command and wipe them out, and through careful political manoeuvring cause every major faction in the Mojave to ally together against them. Hell hath no fury like a woman scorned.
When you start the game, you're on your knees with hands tied while Benny gives you a speech before shooting you in the head. if you choose to not kill him in his own casino and take him with you to legions camp he'll get caught because he doesnt fit in. they tie him up on his knees. you can free him or give him his speech back and then shoot him in the head.
There is a mod that allows the player to craft a bullet "with Benny's name on it" out of the remains of the bullet he fired at the beginning of the game.
In the Fallout New Vegas add-on Dead Money the insane former elder of the Brotherhood of Steel, Elijah, kills dozens of people, brutally tortures Christine, enslaves a mentally handicapped Super Mutant, and forces you to fight your way through dozens of Ghost People to penetrate the Sierra Madre Casino under the threat of death, all so he can access the treasures inside the Casino's vault. In the final confrontation with him, an option for dealing with him is to just let him have the treasure while you waltz away. He'll walk into the vault and trigger a trap, locking himself inside forever.
In Fallout 3 after you've visited most of the rusty abandoned vaults and Vault-Tek headquarters and discovered the true purpose of the vaults and why they went horribly wrong, you have the chance to find a voice recording on an alien spaceship of the Vault-Tek CEO who masterminded the vault system and their true purpose; the recording shows the aliens kidnapped him and performed experiments on him, despite his snivelling attempts to be diplomatic.
In BioShock, Doctor Suchong suffers a remarkably appropriate death. While pondering how to further improve the imprinting of the Big Daddies' programming to protect the Little Sisters, he gets annoyed by one of the little girls. Eventually, he loses his temper and slaps her. Jack finds his corpse, impaled on his own desk by a Big Daddy's drill.
The sequel makes it even more satisfying by revealing that the Big Daddy was Delta (that is to say, you), protecting Eleanor.
Though his death isn't Karmic, what you can do to Sander Cohan after is. After killing him, you can take his picture like how he made you do so to his underlings. The trophy you get from doing so is even titled Irony.
Valkyria Chronicles delivers satisfying ends to the morally corrupt characters of the story. Even Squad 7 is subject to it. The closer a character is to the moral high ground, the better their epilogue is.
The final boss of Disaster Day Of Crisis, Evans, meets his end... At the hands of his own colonel, who actually survived being shot by Evans. Awesome.
In Dead Space, Kendra, after crossing the Moral Event Horizon several times and revealing that Isaac is going insane, steals the ersatz Artifact of Doom that was stopping the monster from its base, thereby nullifying its power. Not five minutes later, said monster smashes her into paste.
In God Of War, Ares is killed by the very man he hoped to make into his Ultimate Warrior, Kratos, who was tricked into killing his own wife and daughter, the only two people he ever loved, by Ares.
Ares: I was trying to make you a great warrior! Kratos:You succeeded.
A variation is present in Dark Forces 2: Jedi Knight. Kyle disarms Jerek, but can't kill him in cold blood. So, he gives him back his saber, and when Jerek charges, cuts him down in self defense.
A sweet one comes to the Obstructive Bureaucrat in Advance Wars: Days of Ruin. The mayor of a group of civilian refugees has been unimaginably unhelpful at every turn, acting horrendously ungrateful to the protagonists every time they save his life and actively hampering their efforts, even though he comes whining to them whenever he's in trouble. In the latter part of the game he attempts to sell out the heroes to the Big Bad to get a vaccine against a looming disease; he's told that there's only one vial and he can either use it on himself or wait for more to be produced from it to help his community. Thinking only of himself, he grabs it and injects it into himself. It was poison; the Big Bad just wanted to see if the guy would really sell out his community.
Greyfield/Sigismundo gets one as well. He attempts to surrender to Lin to avoid being killed. Lin shoots him anyways. This is karmic on 2 counts, 1:The player is fighting Greyfield because he himself executed prisoners 2: He attempts to say Lin's former CO wouldn't kill a prisoner, too bad for him Lin is not Brenner and the only reason he is dealing with Lin instead of him is because he killed Brenner.
In Final Fantasy VI, Emperor Gestahl meets his demise at the hands of his Court Mage scapegoat, falling from the floating island he has long sought to resurrect.
In Metal Gear Solid 3, the Big Bad of the story ColonelYevgenyBorisovichVolgin ultimately suffers this fate. For perspective the man carries 10 million volts of electricity in his body and thus utters the phrase, "Kuwabara", which is based off of a legend that says it can ward off lightning during rain storms, out of a paranoia that his electric gift might make him a lightning rod if it rains. As a villain he is a cruel man that tortures people for fun and is implied to rape men and women alike, but despite having petty evil as a hobby he is still a formidable foe. During the climatic confrontation with Volgin Snake defeats him once with CQC leaving him to die in his exploding base, survives the explosion and begins a prolonged chase piloting the Shagohad where he is lured onto a bridge rigged with explosives and falls into the river below, drives the Shagohad up he collapsed bridge to continue the fight and is shot like a billion times with RP Gs and machine gun fire until he finally collapses. Volgin being ever persistent refuses to give up and screams at Snake in frustration, but his efforts to restart the battle are cut short when a rain storm begins... Throwing off his usual paranoia Volgin refuses to chant his usual "Kuwabara" and states arrogantly, "Who is afraid of a little thunder?" Ironically moments later a lightning bolt strikes him, sets his body on fire which ignites the bullets strapped to his chest which go off and turn his body to Swiss cheese. Naked Snake seeing this remarks, "Fried by a bolt of lightning... A fitting end.".
In the finale of The Witcher the video game, the main villain Jacques De Aldersberg knocks Geralt's steel sword, which is better suited for killing humans, out of Geralt's hands. Geralt simply proceeds to take out his silver sword, which is better suited for killing monsters, and runs Jacques through with it. Although Jacques De Aldersberg is shocked that Geralt would use his monster-slaying sword to kill him, it's pretty obvious that Jacques De Aldersberg is just as bad as, if not worse than, the mindless monsters that Geralt usually slays.
The "kidnapper" in Alan Wake meets an unpleasant and terrifying end at the hands of the forces of darkness, presumably for getting in the way of their plans by fucking with Alan. The revelation that all of his threats regarding Alan's wife were empty makes him only slightly more sympathetic as he's being mind raped by a supernatural entity of indescribable horror, but he was a Jerk Ass.
The man's Boss, Dr. Hartman, fits this trope better. He was aware of the Dark Presence in the lake and wanted to control it so he could bend the world into his own image. For this reason he sought to "acquire" Wake due to how the Prescience seemed to be drawn to those with talents in creativity (such as writing, art, or music). He was the one who convinced Wake's wife to bring Alan to Bright Falls (under the pretense of helping him with his writer's block), set up the whole "Kidnapper" scheme, and later tried to make Alan think that he was a delusional patient under Hartman's care. His ultimate fate? Alan locks him in a room with the same Darkness the "Good Doctor"sought to control, and does so with a rather palpable degree of satisfaction
The Big Bad of Uncharted2 lives by a creed of "No Compassion, No Mercy". When he mocks the main character Nathan Drake for not having the guts to finish him off after kicking his ass, Nathan dismisses him and points out that he might not be willing to do it, but they are. "They" being the mob of merciless compassionless Guardians that immediately tear apart the Big Bad.
Heavy Rain. The origami killer in one scenario can meet his ultimate fate by drowning in rainwater. In another he is shot by the mother of one of his victims that he himself saved.
In the "Undead Nightmare" expansion of Red Dead Redemption, a cutscene involves John Marston listening with obvious distaste to the racist, sexist, bigotted ranting of Herbert Moon. Then Herbert goes outside and meets three zombies, while in the background Marston calmly smoke a cigarette and watches. When the cutscene ends, the player then gets to pop zombie-Moon in the head to put him out of humanity's misery.
After spending Mass Effect 3 stabbing people in the gut with his signature shirasaya blade, at least one of whom was Shepard's friend/love interest, after being beaten and broken by Shepard, Kai Leng attempts to stab him/her in the back while s/he's perusing the Illusive Man's files. Shepard realizes at the last second what is happening and dodges his stab or, if the Renegade interrupt is taken, shatters his sword for bonus points and proceeds to gut Kai Leng like a fish with the omniblade.
Shepard: That was for Thane/Miranda/Kirrahe, you son of a bitch!
In the beginning of The Elder Scrolls V Skyrim, there's an Imperial captain who sends you to your death, even though it was said that you were not on the execution list. If you escape with Ralof, she's the first NPC you kill. It's karmic because it's now you sending her to her death.
Curtis Blackburn of Killer7, an unrepentant rapist, kidnapper, and organ harvester gets mutilated by his own organ harvesting machine after resident Bad Ass Dan refuses to let him have a peaceful, stylish death.
During Full Throttle, the Obviously EvilCorrupt Corporate Executive Ripburger kills old man Corley by beating him to death. At the end of the game, Ripburger falls from a cliff after trying to kill the main cast. Before he goes over, he grabs a license plate bearing the Corley Motors slogan "You can't beat a Corley."
In The Walking Dead, Brenda and Andrew from Episode 2. Brenda of the St John Diary cuts off Mark's legs for food, and leaves him upstairs to bleed to death. Being unaware that all people with intact brain stems turn into zombies upon death, when she has Katjaa at gunpoint in front of Lee, she backs upstairs and is grabbed and bitten by zombie Mark. In a later blink-and-you'll-miss-it moment, Brenda is seen as a zombie, shambling out of the front door of the house. Also, you have the option to kick Andrew into the electric fence that kept the St. John Diary safe from zombies.
One World Of Warcraft quest chain has you infiltrating the Blackrock clan in a Paper-Thin Disguise. One of the quests has you assassinate three of their key figures, one of whom is a worg handler that you can see demoralizing the worgs. When you stab her with one of the scorpid barbs you were handed upon accepting the quest she becomes paralyzed long enough for the worgs to rebel and tear her to shreds.
In the updated Scarlet Halls instance (an amalgamation of the Library and Armory instances), the Scarlet Crusade members who are patrolling the first third of the dungeon are accompanied by starving and presumably mistreated hounds; throwing a food bucket at them causes the dogs to eat them alive and go to sleep, enabling you to pass without incident. The first boss, Houndsmaster Braun becomes frustrated with his dogs midway through the fight and threatens to put them down once he finishes off the party. After the party defeats him, the dogs eat him alive and then tear through an otherwise impenetrable phalanx of Scarlet Crusaders.
Manfred Von Karma of Phoenix Wright of course, though it's debatable whether he was sent to life in prison or was given capital punishment. Phoenix does a turnabout and proves that Von Karma shot and killed Edgeworth's father when Edgeworth threw a gun and triggered the bullet to hit him. Von Karma goes through a long series of events to get Edgeworth guilty of either that murder, or the murder of another man. Why he didn't just wait a few days after the Statute of Limitations to frame Edgeworth for this other murder so that he couldn't be proved guilty is a bit boggling.
He wanted Edgeworth to believe he had murdered his own father (not just to get found guilty for another murder), which he wouldn't have been able to bring up in court unless he brought the case before the statue of limitations expired. Which means, surprise, his desire for a very specific sort of revenge helped lead to his downfall.
In Ace Attorney Investigations 2, one killer fled the country for a few years after successfully testifying in a trial against the man he was framing. Eighteen years later he admits his crime happily now that the statute of limitations is up - but by fleeing the country while still technically a suspect all those years ago, he wound up extending the statute on the case, giving him a one-way ticket to prison once he confessed.
Ace Attorney Investigations features Manny Choachen getting murdered by the leader of a smuggling ring. Said leader ordered Choachen too kill a witness to the ring 10 years prior and the motive as too why said ringleader murdered choachen? Because he was a witness too. Well, technically there were multiple motives but this is one of the main ones.
Fate Stay Night has this happen oh-so-satisfyingly to Shinji Matou in two of the three routes. In Fate it takes the form of fleeing the scene of Rider's annihilation at the hands of Saber and Excalibur only to run into Ilya and Berserker. In Heaven's Feel he meets his end at the hands of his own sister Sakura of all people when he tries to blackmail her into a position where he can rape her. For practically the millionth time. In Unlimited Blade Works, he doesn't die, but he might as well have.
During Arcueid's route in Tsukihime, a combination of factors make Shiki go briefly insane and sexually assault a drastically-weakened Arcueid. The player can choose whether Shiki gets a hold of himself, or gives in to his desire and rapes her. The correct choice, naturally, is to stop; the next night, Arcueid has another spasm and tries to drink Shiki's blood...and hesitates, long enough for Ciel to come to Shiki's rescue. If Shiki gave in to his dark side and raped her, on the other hand, Arcueid doesn't hold back, either...
The Wotch: Natasha Dahlet of DOLLY is turned into a dolly.
In Sam and Fuzzy, this trope is double subverted. Mr. Blank looks like he'll be setting it up when he is dangling from the side of a flying skyscraper and proclaims that Samdoesn't have it in him to let him fall — only to be proven wrong when Sam steps aside and lets Fuzzy unceremoniously kick him off. As it turns out, this didn't take and Blank is later seen climbing up the side of the skyscraper — only to be hit by the corpse of a man he murdered in cold blood earlier on in the arc, loose his footing, and fall off the building to his death together with the corpse.
Bittersweet Candy Bowl has, from its bonus comic alternate universe Disaster Dominos comic, Kizuna, who, after murdering several students, dies of the bloodborne disease one of them carried. It isn't present in the main series. Yet.
The titular business of Suicide for Hire runs on helping people bring karmic deaths onto themselves.
In The Kenny Chronicles Kenny and Funky's feud started when Funky made a porno of Kenny and his girlfriend having sex in a dumpster. A year later Funky fell six stories into a dumpster (a complete accident, though his friends think Kenny is somehow responsible).
Homestuck: After making his Face Heel Turn, Eridan kills Kanaya with the magic wand she made for him. That's not the karmic death. That comes when after Kanaya comes back as a Rainbow Drinker, she snaps said wand in half, then tears her killer a new one with achainsaw.
This is also one of two ways a player that has reached Godtier can be permanently killed (the other being a Heroic Sacrifice), as Vriska finds out.
In the space arc of Arthur, King of Time and Space the False Guenevere's mysterious illness is clone degradation. The karmic bit is that it is excerbated by the spells she casts to prevent Arthur realising she's not the real Guenevere.
In The Order of the Stick, Tsukiko is a necromancer who believes that Humans Are Bastards, and that inversely, the undead are misunderstood people who are better than them. However, in the end, Redcloak proves her wrong by taking control of her wights — while describing the undead as mere "tools" and "weapons" — and having them drain her to death and eat the body.
Believe it or not, it's actually pretty sympathetic, as evidenced by this exchange:
Monster in the Darkness: I know. That's why I'm sad.
Yukyuk, Belkar's third Evil Counterpart in the Linear Guild, made his debut by trying to kill Mr. Scruffy for no reason. After being mentally dominated by Vaarsuvius for a while, he ends up being killed in an attack by his own teammates, while Mr. Scruffy uses him as a body shield.
In The Greatest Gift, Neptune, the father of Venus (Jupiter) and Astra (the real Venus), was Venus' Predecessor Villain and absolutely ruthless mob boss of Las Haygas. In the end, he ends up short changing an assassin he hired to kill a rival mob boss, who kills him in revenge.
Jack O'Connor of Survival of the Fittest cheats in a Ten Paces And Turn duel, only to find his opponent (Adam Dodd) had been walking down a slope (something of a Deus ex Machina). Jack shooting early allows Adam time to find his aim and fatally wound Jack to win the fight and v1. This also apparently makes the fact that Adam was planning on cheating okay simply because Jack tried it earlier.
Laeil Burbank's first kill (and, in fact, first scene in V3,) involves her torturing her helpless cousin, leaving him begging for mercy before killing. Of course, it's only fitting that her death involves a helpless Laeil getting horribly tortured and left to die, also begging for mercy.
It's also a rare case of a Karmic Death where one can feel sympathy for the victim, mostly because her cousin was a dickweed, she had something of a temporary Morality Pet in both Jimmy Trejo and Eddie Sullivan, and the guy who tortured her, JR Rizzolo, was a monster. And there's also her tragic Back Story...
In another example, rapist and literal lady-killer Adam Reeves has a two-for-one when he gets his nuts blown off right before his death at the hands of Alexis Machina.
The Accuser: That's what Dr. Pirot gets for helping a serial killer to survive execution.
My Little Pony, In "The Glass Princess", the Raptorians get turned into glass.
In Justice League, during a battle with his brother Orm in the aquatic underground, Aquaman has Orm hanging off a frozen cliff, begging his brother to have mercy. After he said "You're weak! You're not fit to...(slips)" (Had the sentenced have been finished, he would have likely said "rule"). Aquaman stares, walks up to Orm while he hanging on the cliff, extends his hand and... picks up his trident, leaving Orm to fall to this death.
Aquaman: I believe this is mine.
It's worth considering that Orm threatened Aquaman's son earlier. Clearly, that's one heck of a Berserk Button.
Another example (although Superman didn't know it at the time), was in "Twilight of the Gods", with Darkseid dying when Brainiac's home-base overloaded in his aim to search for the Anti-Life Equation. Superman probably wouldn't have thought this was fitting death given what he did to him in their last encounter. Darkseid, who took a received end of a Roaring Rampage of Revenge seemed to find Karma's decision quite funny since Superman didn't finish him off, and spited him in his last word(s):
Metalocalypse features a slimy PR lady-slash-cult leader get squished by the very comet she tried to kill everyone with.
Aang actually sits down and discusses this trope with Avatar Kyoshi, no doubt hoping his upcoming battle with Fire Lord Ozai could end the same way as her battle with Chin the Conqueror.
Aang: But you didn't really kill Chin. Technically, he fell to his own doom because he was too stubborn to get out of the way. Kyoshi: Personally, I don't really see the difference. But I assure you, I would have done whatever it took to stop Chin.
All of the examples in Hoist by His Own Petardexcept "Arctic Splashdown", "Mystery of the Lizard Men" and "Pirates from Below."
"Arctic Splashdown". While trying to murder Dr. Quest, the Big Bad is blown up by the Self-Destruct Mechanism of the rocket whose guidance control he was trying to steal.
"Riddle of the Gold".
An assassin named Ali is killed by a tiger released by the villains while trying to assassinate Dr. Quest.
The Villain working for Dr. Zin is killed by the leopard pet of the man he murdered earlier.
"Calcutta Adventure". The enemy Mook pilot strafing the Quests is killed when his plane runs into some trees, has its wings ripped off and crashes.
"Shadow of the Condor". The Big Bad likes to shoot condors who live near his castle in the Andes. As he's trying to shoot down and kill Race Bannon in an aerial duel, a condor attacks his plane in revenge and causes him to crash into a mountainside.
"Turu the Terrible". The Big Bad is killed while trying to save the titular pteranodon he used to terrorize and enslave native workers.

"The Fraudulent Volcano". A group of enemy mooks flying in hover platforms ram into a cliff and blow up while trying to kill the Quests.
"House of the Seven Gargoyles". Dietrich (the dwarf masquerading as a gargoyle) is murdered by his boss Ivar.
Played straight in the unedited version of Batman Beyond Return Of The Joker, in which the Joker is fatally shot by a young Tim Drake, temporarily unhinged by the Joker's mental and physical tortures. Largely averted in the edited-for-kiddies version, where his death is a not-very-ironic accident. In any case, the Joker himself denies it:
Joker ends up suffering this twice, after using a small device on Tim's neck to inject his own DNA and turn Tim into the new Joker. The new Batman puts a permanent stop to him by destroying the device with one of the Joker's own electrocuting buzzers.
Corpse Bride. Barkis Bittern, who lured Emily to her doom so many years ago for her money and then attempted to do the same to Victoria, makes a sneering toast to her at her and Victor's interrupted wedding ceremony and downs the goblet of poisoned wine that Victor was going to (willingly) drink. Once dead, he is left at the mercy of enraged corpses.
Phantom Stranger: Ultimately it was karma that delivered the final blow to Joe Chill. ...Funny how Chill just happened to be under that crumbling ceiling when it came down.
Spectre: I wouldn't know anything about that...
Also, in the series finale, Batmite succeeds in getting the show cancelled for a Darker and Edgier one, but as a light-hearted and silly charater, there's no room for him in the new show, and he is erased from existence.
Megabyte in Reboot had this happen to him in season 3, though he ended up Not Quite Dead in season 4. After being spared by Matrix Megabyte tries to escape to the Supercomputer, but Mouse changes the portal's destination to the Web, which is supposed to be fatal to viruses. Megabyte had previously sent Bob to the Web back in season 2, so being sent to the Web himself is an ironic end, had he not survived via Retcon.
The South Park episode "Reverse Cowgirl", has Clyde's mom being a bitch about her son leaving the toilet seat up. When Clyde once again leaves the seat up, guess what happens.
In 1599, the Jivaro tribe arranged one on the Spanish governor who worked them to death mining gold: after their uprising they took him captive and poured molten gold down his throat. After this episode it took 250 years before the Europeans dared to make new contact with them, and were far more courteous the second time around.
Oskar Dirlewanger, German officer during World War II, led a unit which was one of the most brutal and barbarous of the Eastern Front . Immediatly after the end of the war, he was imprisoned and died in his jail, beaten slowly to death by his Polish wardens throughout 5 days.
Roland Freisler, who was presiding judge of the Nazi "People's Court" in World War II. He presided over Nazi show trials and was responsible for ordering the execution of the July plotters. As he was trying one of the plotters, a USAF bombing raid caused one of the columns of the People's Court building to fall and crush him; he was found still clutching the court documents he had stayed behind to save. When what was left of him was brought into hospital, a worker remarked: "it is God's verdict". To add to the irony, the man he was about to sentence to death later became the presiding judge of the Federal Republic of Germany's Constitutional Court.
The poison used by Hitler and other top Nazis to commit suicide was Hydrogen Cyanide. This was the same chemical agent used on their orders to exterminate eleven million Jews, Communists, homosexuals, Roma, Slavs and other "untermenschen" in the death camps.
Benito Mussolini, above all else, wanted to restore Italy to Rome's power and glory. He not only failed, but died just as a failed general would have in Roman times: killed by an opposing Italian faction, and then strung up by his heels in public to be abused by a mob and pecked at by crows.
Pirate captain Francois L'Olonnais was infamous for having eaten a Spaniard's heart in front of him. On another occasion he fed part of one prisoner to another. He was eventually killed and devoured by native cannibals.
Josef Stalin had put so much fear into his minions that when he went to bed and ordered them not to disturb him, they didn't dare to do so. Unfortunately, he then had a stroke and was left lying on the ground for a whole day before they checked on him far too late. If his goons hadn't been so scared of his wrath, they might have gone in to check on him when he didn't come out at his usual time, and then gotten the doctors in to save him in time.
