** In Season 6's "Test of Faith", a student at a middle school is too scared to report that a gang member killed his teacher, at which point he buys a gun to protect himself if he runs into them again, also at which point Walker substitutes for the slain teacher. [[spoiler:When he sees one prospective new member of the gang try to kill a fellow classmate who'd been helping out a lot to curb gang violence, he tries to stop that would-be gang member from shooting her, only for ''him'' to accidentally shoot her, having accidentally dropped his backpack with the gun in it! He soon feels guilty of this mistake and tells Walker what really happened, tipping him off to the killers in the process. Luckily, his classmate survives and has to undergo rehab, since the bullet hit her spinal column, and he gets off with community service and doesn't face any serious punishment.]]

** In Season 7's "[[Recap/WalkerTexasRangerS7E12LostBoys Lost Boys]]", Bobby Landrum, the best friend of Carlos's nephew, Jesse Estrella, participated in a heist at an electronics warehouse, which was stopped by the Rangers and ended with the murder of Dallas Police detective Bill Sadler. The gun used in the murder belonged to his employer at a video arcade and the mastermind of the heist, [[VillainOfTheWeek Johnny Blade]], and when Blade leaves the gun in his hands after the fact, Bobby [[HastilyHiddenMacGuffin hides it]] in Jesse's dresser drawer in a bout of panic. When Blade demands that Jesse return his gun and keep silent of what happened or else he will murder his mother, Theresa, it goes FromBadToWorse due to Theresa and Carlos finding it first, leading up to Jesse taking the blame for Sadler's murder, as well as Theresa being kidnapped by Blade and his gang and held for ransom to blackmail him to take the rap for it. A guilt-ridden Bobby soon realizes the ramifications of his actions and eventually comes forward and confesses.

* ''Series/{{The Imperfects}}

* ''Series/{{The 100}}'':

** The most heartbreaking instance may be when G'kar, his longtime nemesis, accepts an official apology from the Centauri Emperor for crimes committed against the Narns and [[ObliviousGuiltSlinging approaches Londo in good spirits]], extending a tentative hand of friendship. The problem: [[spoiler:Londo made a deal with the Shadows only hours before that would result in another Narn-Centauri war]]. The look on Londo's face as he realizes his mistake is [[TearJerker Tear Jerking]].

--->'''Londo:''' He said... ''That we are both damned.''
** Another instance of this happening to Londo (Seeing a pattern?) made it into latter season's credits, with Londo watching the [[spoiler: orbital bombardment of the Narn Homeworld with outlawed Mass Drivers]] [[http://youtu.be/bjIlqrAfbbg See Here.]] (spoilers, obviously)
** Also in that show is Delenn upon watching Dukhat die after being attacked by Earth Alliance warships orders their immediate destruction. "NO MERCY!" [[spoiler: When she calmed down she was horrified to learn that her actions had started a full-scale war.]]
** [[spoiler:Lennier]] had been struggling with his SubordinateExcuse for five seasons and finally gets his chance when [[spoiler:[[MurderTheHypotenuse Sheridan is accidentally trapped in a room filling with poisonous gas]]]]. [[MurderTheHypotenuse He walks away]], only to realize what he's doing moments later and runs back to [[spoiler:help Sheridan, only to find him rescued by others]].
** In the second season finale, Captain Sheridan gets one after he orders the station's defense grid to open fire on a Centauri cruiser in self-defense, resulting in the cruiser's swift destruction. Definitely justified, in that every action he had taken had been with the intent of protecting lives, rather than taking them, only for him to be backed up against the wall and only left with the one option. [[spoiler:He has a similar reaction midway through the third season when he does the same thing... to an Earth Alliance destroyer.]]

* In ''Series/{{Battlestar Galactica|2003}}'', Gaeta, during the [[spoiler:mutiny on Galactica in Season 4. After Gaeta helps Zarek take over Galactica, Gaeta insists on giving Admiral Adama a court-martial for conspiring with the Rebel Cylons. But when Zarek has the [[MoralEventHorizon Quorum of Twelve gunned down]] for refusing to recognize him as President over Laura Roslin, Gaeta has a bit of a [[VillainousBSOD revelation]] while looking over their dead bodies.]]
-->[[spoiler: '''Gaeta:''' [[HeelRealization We--we had the truth on our side. Now... now]]...]]\\
[[spoiler: '''Zarek:''' [[WellIntentionedExtremist The truth is told by whoever is left standing]].]]

** During "Back to Reality", Kryten has one when he thinks he's killed a man in self-defense, strong enough to drive him to consider suicide. [[spoiler:Which was because he and the others were in a hallucination designed to push them to that point.]]
** Lister, in "Tikka to Ride", asks this when he realises his maniacal obsession for a curry has completely smegged up history. Unfortunately, his accomplice in this is Kryten's spare head with his behaviour protocals removed, who doesn't get that it's a rhetorical question.

* Franchise/StarTrek:

*** In "[[Recap/StarTrekTheNextGenerationS4E16GalaxysChild Galaxy's Child]]" this is basically Picard's reaction when he discovers that an alien lifeform was fighting back so hard only because she was defending her unborn child.
--->We're out here to explore, to make contact with other life forms, to establish peaceful relations but not to interfere. And absolutely ''not to destroy.'' And yet look at what we have just done.

*** PlayedForLaughs in the episode "[[Recap/StarTrekDeepSpaceNineS02E08NecessaryEvil Necessary Evil]]" when Rom walks in on someone trying to smother Quark with a pillow. His shrill shrieks get Odo and the rest of security's attention and Odo, getting him to calm down, tells Rom that he saved his brother's life. Rom feels proud of it... until he realizes that that means he isn't getting the Bar, causing him to shriek again. And on the med bed, Quark lets a shit-eating grin form on his face.

*** In one episode, Torres utters this exact line when she realizes the race of robots she is helping were responsible for the extinction of their creators.
*** Another was the Doctor realizing that [[spoiler:he had disregarded his medical training and chosen to save his friend instead of someone he barely knew in a crisis situation. Being a medical program with a vast amount of ethical programming, he enters an almost literal HeroicBSOD over the matter.]] To be clear: [[spoiler:There was ''no'' difference between the two cases from a medical standpoint, but he could only save one and he had to make a snap decision; it wasn't that his ethical programming failed so much as that he had never been programmed in how to make a decision where there was no obvious logic to indicate a correct choice (or, in fact, a clear correct and incorrect choice at all). He didn't actually do anything wrong, he had the reaction because he couldn't cope with having made a life-or-death decision based on something other than strict medical ethics.]]

* ''Series/{{Supergirl|2015}}'' sure loves this trope.

* In ''Series/TheWalkingDead'', after Daryl punches Negan for [[spoiler: taunting Rosita about Abraham's death,]] Negan responds by [[spoiler: brutally murdering Glenn.]] The look on Daryl's face is one of pure horror, as he slowly realizes what his actions have caused.

* ''Series/TheWheelOfTime'': Perrin screams in agony after he kills his wife Laila accidentally. He is understandably in shock for much of the early episodes.

* ''Series/MayfairWitches'': Rowan is horrified to learn she almost killed her boss inadvertently with her newfound telekinesis. Then it happens again, leaving Rowan distraught.

* ''Series/MayfairWitches'': Rowan is horrified to learn she killed her boss inadvertently with her newfound telekinesis. Then it happens again, leaving Rowan distraught.

* ''Series/{{Andromeda}}'': In an alternate timeline Gaheris Rhade reacted this way when he realized his betrayal of the Commonwealth did not result in a better safer universe, but a lawless chaotic dystopia facing imminent doom.
* ''Series/TheAndyGriffithShow'': Opie goes through this when he kills a bird. He ends up trying to make up for it by raising her babies until they're old enough to leave the nest.

** In the season finale, [[spoiler:Luthen]] hears [[spoiler:Maarva]]'s funeral speech and sees how it inspires people to rebel through hope more successfully then he ever did through his amoral scheming and stoking of hatred, then barely escapes from the massive, deadly riot on Ferrix that he helped cause, forcing him to see firsthand the human cost of his methods. As he stumbles away from the city, he looks back and sees smoke rising from the streets with a look of despair seemingly having had a major epiphany about his "PayEvilUntoEvil" attitude and where it's going to lead.

* ''Series/{{TheImperfects}}

* ''Series/ICarly'': Freddie utters this line as a group (''What have WE done?'') when the gang realized that bringing back Marta made Lewbert's life even worse.

** Freddie again evokes a variation of this trope in the extended version of ''iSaved Your Life''. After his break-up with Carly, his face changes expression while in the elevator and asks himself in regret, "What did I do?" Cue a zoom out of the Bushwell building as Freddie yells '''"WHAT DID I DO?!"'''
** Spencer in the flashback of "[[Recap/ICarlyS04Ep03IGetPranky I Get Pranky]]" upon realizing his prank truly hurt his classmates

* ''Series/Kingdom2019'': Yeong-shin has this reaction after feeding the villagers with human meat, since it ended up turning almost everyone in the village into zombies.
* In one episode of ''Series/LawAndOrderSpecialVictimsUnit'', a teenage human trafficking victim kills his own sister (also a victim) when she tries to run, for fear of [[IWillPunishYourFriendForYourFailure what will happen to him and the other victims if she gets away]]. When Huang suggests that the sister might have intended to bring back help for the others, the boy breaks down completely as he realizes he quite possibly killed his sister for trying to save him.
* ''Series/LawAndOrderUK''. Jamal Clarkson, who shot DS Matt Devlin in order to avenge his brother's murder, completely breaks down when Matt's partner Ronnie makes him understand that Matt wasn't a racist and had nothing to do with the botched investigation into his brother's death, meaning that he's not only failed in his mission, he's killed an innocent man.
* ''Series/LipService'': The driver who struck [[spoiler: Cat]] accidentally had this reaction, becoming so distraught the hospital staff had to sedate him.
* In ''Series/{{Lost}}'', Jack has this reaction after finally [[spoiler:escaping from the island.]]
-->"We have to go back!"

** In "Private Channel", Mr. Williams, who plans to blow up the plane, is overcome with remorse when he hears the passengers' thoughts through Keith Barnes' Walkman. One passenger's thoughts about his young daughter Jenny strike a chord with him as he was [[CrusadingWidower motivated by the death of his own wife and daughter]], who was much the same age as Jenny.

'''Crichton:''' Here's how it lays out. Are you listening Stahleek? Grayza? Wormhole weapons do not make peace. Wormhole weapons do not even make war. They make total destruction, annihilation, Armageddon. ''People'' make peace."\\

** In "[[Recap/BreakingBadS3E7OneMinute One Minute]]", after a deception allows Walter and Jesse to elude him, Hank is enraged to the point of severe PoliceBrutality against Jesse. After he calms down, he is visibly horrified at his actions.
