* ''Series/BetterCallSaul'': In the penultimate episode, as a cornered Gene is about to strangle Marion, who has discovered his identity as Saul Goodman, she angrily tells him that she trusted him. As a man who got his big break as a lawyer in Elder Law and worked tirelessly to defend seniors who were exploited, this seems to trigger something in Gene as he realizes how far he has fallen. He stops trying to attack her and just runs out of the house. WordOfGod states that this was the first moment in years that a deeply buried Jimmy [=McGill=] was able to emerge.

** Anya utters this after her vengeance spell summons a spider which [[HeartTrauma rips out the hearts of 12 frat boys]] in "[[Recap/BuffyTheVampireSlayerSS7E5Selfless Selfless]]".

---> '''Tegan''': "Sorry, '''''[[AssInAmbassador Ma'am...]]'''''

*** 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.

* ''Series/YTheLastMan'': Hero is distraught and then shell-shocked after she accidentally kills Mike, her lover, during an argument.

* ''Series/RupaulsDragRace'' often invokes this trope in the reunion episode. Once the contestants actually watch the season, they're often aghast at how bitchy they sound, and they make it clear that they did not intend to come across that way.

* ''Series/MidnightMass'':

*** In "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.

*** Kevin Uxbridge from "The Survivors", who is really an immensely powerful being called a Douwd. Upon learning of the death of his wife at the hands of an invading alien race called the Husnock, he snapped and annihilated the ''entire Husnock species'' in one strike. Already deeply pacifistic, he was horrified beyond belief at this act of violence, and swore to live in exile for the remainder of his life, accompanied only by a facsimile of his wife and their homestead as a reminder of what he lost and what he did.

* In an episode of ''Series/StrongMedicine'', a boy comes into the hospital after having a police officer use a Taser on him (They later find out that the only reason he reacted so badly was because of mercury poisoning.) Lu then spends the entire episode going into an Ideological Screed against the female cop. Later on, another boy comes into the ER, with the same cop. She mentioned that she was chasing him and reached for her Taser, but hesitated. Lu began to praise her (and herself) for this, but then the cop mentioned that, because she hesitated, the boy ran out into traffic and got hit by a car.

* ''Series/WhyWomenKill'': Bertram's former priest realizes with horror that when he told Bertram as a child that euthanizing his mother could be forgiven, then it was taken to mean (involuntary) euthanasia of other people was ''also'' okay, and he's killed ''26 people'' since.

* 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.]]

* PlayedForLaughs in the third-season finale of ''Series/TheBigBangTheory''. Howard and Raj make an account for Sheldon on an online dating site. Sheldon gets matched with Amy Farrah Fowler, [[DistaffCounterpart who is almost exactly like him]]. Howard's reaction when he sees the two together:

** In Season One, Diane goes through a non-verbal version of this, after Coach and the others convince her to throw a baseball down the hall into the pool room, where Coach is standing. ItMakesSenseInContext -- Coach is proving a point to her about his uncanny success at bunting... with his noggin. It's even worse for poor Diane when you consider that she fully expected to ''miss'' -- but as Sam notes, that's part of the point.
* In ''Series/TheCloser'', after several episodes of not feeling any remorse for facilitating a VigilanteExecution the previous season and not taking the victim's family's lawsuit against the department seriously, Brenda finally breaks down sobbing "WhatHaveIDone?" at the end of season 7 episode 5, after everyone in her unit, plus Chief Pope, Commander Taylor, and her husband are all subpoenaed.

*** First, he has a downplayed example in the denouement of [[Recap/DoctorWhoS35E5TheGirlWhoDied "The Girl Who Died"]] as he ponders the possible consequences of his rash decision to [[spoiler:save Ashildr's life in a way that might — and does — render her a functional immortal]]. As it turns out, this paves the way for [[spoiler:her betraying him and capturing him for the Time Lords — which inadvertently leads to the death of Clara Oswald, his beloved companion]] in [[Recap/DoctorWhoS35E10FaceTheRaven "Face the Raven"]] near the season's end, whereupon he's subjected to ColdBloodedTorture, has a '''massive''' SanitySlippage, and...

* ''Series/FamilyTies'': In the second-season episode "Uncle Ned", after Ned (Creator/TomHanks) comes home drunk -- even drunker than when he went to his job interview -- he gets into a huge argument with the family over whether he has a problem. He eventually gets into a struggle with Alex and accidentally punches him ... setting the trope in motion and forcing Ned to finally realize he has a problem.

** As Joffrey rises to ever new heights of cruelty and perversion, Cersei finally acknowledges that having three inbred children with her twin brother ''wasn't'' such a great idea — considering what it did to the Targaryens — to say nothing of putting the most unstable of them on the Iron Throne itself. She breaks down in tears from the sheer knowledge that the son she loves (despite everything) is a psychopath. Nevertheless, in later episodes, she undergoes a mild SelectiveObliviousness.

** In the season 2 episode "[[Recap/GleeS2E19Rumours Rumours]]", Artie is so frustrated and heartbroken by the possibility of Brittany, who [[ICantBelieveAGuyLikeYouWouldNoticeMe he never thought would even consider being in a relationship with him]], cheating on him with fellow cheerleader Santana, that he ends up accidentally calling her stupid, causing her to break up with him in tears. What follows is a musical version of this trope, as Artie lets his feelings pour out in a heartbreaking rendition of "[[https://www.youtube.com/watch?v=j-tNXLSjI_0 Never Going Back Again]]".

** Later in the series Guinevere is given an enchanted bracelet that rekindles her feelings for Lancelot and leads her to make-out with him on the eve of her wedding to Arthur. They're caught, and the trope is played out in a truly heart-rending manner. Since Gwen never discovers that she was enchanted, she honestly ''has no idea'' why she betrayed Arthur - she didn't want to, and she can't understand why she did. The question: "what have I done?" is taken quite literally.

*** In the first season Tommy has one immediately after Rita's spell is broken. It is probably {{justified|Trope}} because he should be going into shock.

** Sam after he finds out that by killing Lilith, [[spoiler: he actually released Lucifer, and that him drinking demon blood didn't actually increase his powers - it was simply a MagicFeather that Ruby used to control him.]]

** [[spoiler: Both of the brothers in "My Brother's Keeper", the season 10 finale, where they [[HeelRealization realize]] that they've become [[HeWhoFightsMonsters just as bad as the things they hunt]], if not [[VillainProtagonist worse]].]]

* ''Series/ControlZ'': [[spoiler:Gerry]] is horrified when his punch puts [[spoiler:Luis]] into a coma, and even more after [[spoiler:Luis' death]].

** In another episode, a husband and wife kill their baby after he starts showing symptoms of a degenerative disease that killed their first son. They find out after it's too late that he was simply sick because of the pesticide his mother used in the garden, and if she had stopped using it, he would have been perfectly healthy.

** A girl who survived a car accident is found murdered in her hospital bed. It turns out to have been by the mother of her friend who was outraged at the accident nearly killing her daughter. Mac has to break it to her that [[spoiler: because of a mix-up at the scene, the girl in the bed ''was'' the woman's daughter. She remembers her waking up under her bandages to ask "Mom?" but she assumed it was the friend asking for her own mother. The woman is completely destroyed to realize her daughter died not knowing why her mother was doing this]] as Mac notes, nothing the courts can do can be worse than what the woman is already going through.
