* ''WesternAnimation/TheLegoMovie2TheSecondPart'': At the start of the movie, Lucy admonishes Emmet for his [[ThePollyanna niceness and optimism]], saying he needs to [[TookALevelInBadass grow up and become tough]], just like her, advice he ends up taking to heart. [[spoiler:After she finds out that the Systarians are as [[SheepInSheepsClothing nice as they claim to be]] and actually want to ''stop'' Armamageddon, she tries to talk Emmet out of stopping their plan. Unfortunately, her abandonment of her badass persona and claim that she secretly liked bright and colorful things convinced Emmet she's been brainwashed, as "The real Lucy would never say that". Not to mention her advice had led Emmet to become [[FutureBadass Rex Dangervest]], who has all of the cynicism and toughness she wanted but none of the kindness and empathy she loved about Emmet.]]

* ''WesternAnimation/TheLegoMovie2TheSecondPart'': Lucy tells Emmet that times have changed, that being soft and silly isn't cool anymore, and he must be "tough and battle ready." Emmet decides to do so. Lucy trying to convince Emmet that it's okay and she prefers him to be the soft, silly, gentle guy she cares about only reinforces the idea that she's been brainwashed, since Emmet can't believe that Lucy would ever willingly say such a thing. It also turned out that a gritty, tough, and hardened Emmet would turn out to be Rex Dangervest, who doesn't care about his friends or the rest of the universe.

* Gran Apache spent years of his Wrestling/{{AAA}} career [[OverProtectiveDad trying to wreck the relationship between his daughter Fabi and Billy Boy]]. Billy Boy did eventually snap, but rather than leave Fabi, Billy Boy became a {{Domestic Abuse}}r.

* In ''WesternAnimation/TheIncredibles'', Syndrome builds a robot able to [[AwesomenessByAnalysis analyze]] the combat style of its opponents and adapt to defeat whatever tricks they were using to fight it. This works very well for him until [[spoiler:he tries to stage a fight with the robot, which realizes Syndrome was fighting it by use of a remote control...]]

* In ''WesternAnimation/{{Megamind}}'', [[DiabolicalMastermind Megamind]] sets out to create himself a new SuperHero ArchEnemy, giving [[FlyingBrick Metro Man's]] powers to another character and then, when this less-than-heroic superhero is not so keen to fight, provoking him by insulting him in various ways. While the "creating a hero" part GoesHorriblyWrong, the "creating an enemy" part works all right -- only this time, the invincible guy after Megamind [[MurderIsTheBestSolution is not going to settle]] for just putting him in the CardboardPrison.

* In ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'', this occurs with both main characters. Sweeney wants revenge for his false imprisonment, but gradually slips into a philosophy thanks to a bout of BlackAndWhiteInsanity. Mrs. Lovett [[AllLoveIsUnrequited loves Sweeney and wants to be with him]], but he's too busy pining for his [[TheLostLenore dead wife Lucy]]. [[spoiler: In the end, the two plots intersect: Sweeney's obsessive bloodlust sees him unknowingly murder Lucy, who wasn't dead after all, just driven insane by her trauma. Mrs. Lovett, who knew the truth but kept it hidden for her own agenda, ''does'' get Sweeney all to herself--at least for the thirty or so seconds between TheReveal and Sweeney [[KillItWithFire burning her alive for lying to him.]]]]

* Theatre/{{Hamlet}} did reach his end goal of killing the king...

* ''WesternAnimation/TheBadGuys'': [[spoiler:Professor Marmalade]] manipulates the Bad Guys into a HeelFaceTurn with the assumption that VirtueIsWeakness and will make them easier to manipulate, including finding a way to turn their caper skills towards a zeal for good. This ends up biting him in the rump in a big way, as this gives the Bad Guys both the skill and motivation needed [[ALessonLearnedTooWell to band together and foil his evil plot]].

* In the Sorcerer's Apprentice sequence of ''{{WesternAnimation/Fantasia}}'', MickeyMouse brings a broomstick to life to carry buckets of water to fill his master's cauldron. However, he doesn't know enough about magic to stop the broom once the job is done and the cauldron overflows. Mickey tries to destroy the broomstick with an axe, but each piece [[HydraProblem turns into a new broomstick with its own buckets]].

* Several man-made [=SCPs=] collected by the Wiki/SCPFoundation have this as their origin story. Mostly those made by The Factory, Dr. Wondertainment or Prometheus Labs (though the former two are so enigmatic that it's hard to tell ''what'' they were trying to accomplish).

* The backstory of the Monster Girl Encyclopedia has an example that managed to go horribly wrong ''and'' horribly right at the same time. A [[HornyDevils succubus]] takes the throne of the Demon King with help from a human hero she'd fallen in love with, and uses her powers to give all the monsters succubus aspects so as to turn their hatred towards humanity into lust and affection. The part that went horribly wrong: Monsters can only give birth to other monsters, [[OneGenderRace all of whom are female]], thus dooming the species to a slow extinction. The part that went horribly right: The newfound affection did not come with a ''conscience'', leading to monsters becoming sex-crazed rapists. [[SarcasmMode Good judgment call there, Demon King]].

* UsefulNotes/{{Hinduism}} has a couple instances where a HoneyTrap goes a bit too far.
** When in need of seducing demons, Vishnu takes the form of a beautiful female avatar, Mohini, and never fails to save the day. The problem is that Mohini is so damn gorgeous that when Shiva sees her, he falls in love, causing some amusing hijinks. At least one of those involve Shiva and Mohini having sex and producing the god Shasta.
** Tilottama is a beautiful apsara created by Brahma's orders to seduce two unbeatable demons, Sunda and Upsunda, into killing each other. When Tilotamma returns, however, it's the gods' own turn to fall in love with her, so much that Shiva and Indra grow many heads and eyes, respectively, in order not to stop looking at her.

* Theatre/{{Hamlet}} did reach his end goal of [[KillEmAll killing the king...]]

* In ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'', this occurs with both main characters. Sweeney wants revenge for his false imprisonment, but gradually slips into a KillEmAll philosophy thanks to a bout of BlackAndWhiteInsanity. Mrs. Lovett [[AllLoveIsUnrequited loves Sweeney and wants to be with him]], but he's too busy pining for his [[TheLostLenore dead wife Lucy]]. [[spoiler: In the end, the two plots intersect: Sweeney's obsessive bloodlust sees him unknowingly murder Lucy, who wasn't dead after all, just driven insane by her trauma. Mrs. Lovett, who knew the truth but kept it hidden for her own agenda, ''does'' get Sweeney all to herself--at least for the thirty or so seconds between TheReveal and Sweeney [[KillItWithFire burning her alive for lying to him.]]]]

* In 2022, Wrestling/{{Edge}} decided to [[FaceHeelTurn stop caring what the fans thought about him]] because [[TheUnfettered it was holding him back]], and [[TheCorrupter encouraged others to do the same]]. This worked great-- until his recruits declared that they just had one last thing to get rid of, namely ''him''.

* In ''Machinima/RedVsBlue'', Project Freelancer's bad ideas worked much better than their good ones. There's a reason why in the present day its operations consist largely of recovering its agents' armor and enhancements.

* During ''[[Machinima/YogscastMinecraftSeries Cornerstone]]'', Smiffy of LetsPlay/HatFilms attempts to troll LetsPlay/{{Sjin}}, LetsPlay/{{Rythian}} and LetsPlay/HannahRutherford by posing as a Creeper. They panic and then kill him.

* Wiki/TaerelSetting: The kin'toni project. (Project Bloodmoon), yes, they made their superhuman soldiers, but shame they turned on the Xeara zu'aan empire right?

* In ''WesternAnimation/{{Megamind}}'', [[DiabolicalMastermind Megamind]] sets out to create himself a new SuperHero ArchEnemy, giving [[FlyingBrick Metro Man's]] powers to another character and then, when this less-than-heroic superhero is not so keen to fight, provoking him by hitting multiple {{Berserk Button}}s. While the "creating a hero" part GoesHorriblyWrong, the "creating an enemy" part works all right -- only this time, the invincible guy after Megamind is not going to settle for just putting him in the CardboardPrison.

* ''WesternAnimation/AstroBoy''. The President wants to put the evil red orb inside the war machine to make it more aggressive and violent. Well, it ''worked''...
