My God, What Have I Done?



"''"The awful daring of a moment's surrender

which an age of prudence can never retract."''"

- TS Eliot, The Waste Land

Well-intentioned but misguided character -- very likely a Tragic Hero or Anti Villain-- comes to realize that his actions have caused incredible damage, physical pain, emotional pain, or even loss of life. The usual line that comes after this is the title of the article (sometimes, without the "My God"). Tears of Remorse may accompany it.

Often the realization only comes when someone/something close to the person is hurt or destroyed. In quite a few cases, that "someone/something close" is the very entity he was trying to get rid of to begin with.

Usually delivered dramatically, sometimes, well, over-the-top. A villain might utter this line if they're about to take the Last Second Chance. Or a hero after being freed from The Virus, being Brainwashed and Crazy, or a Super Powered Evil Side.

Sometimes followed by Must Make Amends.

Compare These Hands Have Killed, which can occur even the first time the character has killed, even justifiably.

See also Screaming At Squick.

Often the result if the protagonist becomes an Unwitting Pawn. Sometimes combined with Heroic BSOD; common with Villainous BSOD. Can be a self-inflicted What the Hell Hero. Contrast I Did What I Had to Do, Be All My Sins Remembered, and I Regret Nothing. Compare Its All My Fault, Heel Realization and Kick the Morality Pet. See also Out Damned Spot, Being Evil Sucks, Nice Job Breaking It Hero, and Sympathetic Murder Backstory. May be the result of an all too successful Pygmalion Plot to Teach Him Anger.

 * Robin Mask suffers from this when he thinks he's killed Kinnikuman during their fight in the 20th Choujin Olympics. Especially noteworthy in that Robin was previously in an Unstoppable Rage- once it wears off, he realizes that he was taking the fight to seriously. While he's lamenting, Kinnikuman puts him in a finishing hold, winning the match.
 * Dragonball Z: Vegeta had this twice, once when he allowed Perfect Cell to reach his perfect form and again when he allowed Majin Buu to resurrect.
 * Gohan had this too, thanks to his cockiness.
 * A short while before the above example, Goku had one of these moments on his own when Piccolo reminded him that Gohan was partially human, didn't share Goku's lust for battle, and thus didn't find any pleasure at all in getting curbstomped by Cell while his father simply looked on from a distance.
 * In the OVA of Angel Sanctuary, Katan says this while looking down at his hands in horror after.
 * Magical Project S Misao Amano (as her evil Magical Girl alter ego Pixy Misa) was destroying the city and almost killed her only friend Sammy and her parents, to the point where she, this was justified although it was her other personality did this and was unaware of what she did. The twist here was that.
 * Guld Bowman In Macross Plus gets a simultaneous double helping of this, when he finally overcomes his Trauma Induced Amnesia in the middle of a Macross Missile Massacre which he believes has killed Isamu Dyson, the person who he had blamed for the trauma..

 * Somewhat averted as
 * For a villainous example, in the 3rd Naruto film (Guardians of the Crescent Moon Kingdom) the baddy Ishidate accidentally turns his employer--and more importantly, paymaster--to stone. Oh Crap.
 * Sakura has this reaction when she realises what the promise she got out of Naruto did to him.
 * Digimon Adventure 02: It's discovered that Big Bad Ken Ichijouji, definitely an Evil Overlord with a Zero Percent Approval Rating, never knew Digimon were sentient, thinking the Digital World to be a very, very realistic video game. He gives this line once he finds out he's done real harm, and makes a Heel Face Turn.
 * Yamaki of Digimon Tamers actually yells this under the dramatic and appropriately messed-up sky created by his program Juggernaut, an attempt to purge digital life from reality that instead results in a massive and highly dangerous breach between the worlds. Of course, this a fellow about whom the line, "Looks like your pal Yamaki ripped open the sky again," has been uttered. This of course leads to him being fired, and after a good sulk, he begins his Heel Face Turn.
 * Beelzemon spends a good deal of time wandering the Digital World listlessly, thinking back over his actions after . He's so disgusted by himself that he completely loses the will to fight and even to live, not even trying to fight back while a group of Chrysalismon beat him halfway to death.

 * The impact of this cannot be fully felt if you don't realize that up until this moment Renton (and many members of the audience) didn't realize that the entire time he's been fighting enemy LFO's, he's been killing people. He simply thought that enemy LFO's were robots.
 * Lelouch from Code Geass has a Delayed Reaction version of this when the memory of his murder of from the previous episode causes him to vomit (you see the bathroom sink water running indicating he did get sick).

 * Darlton gets one of these
 * Mikoto from Mai-HiME breaks down when she realizes.
 * Shizuru also gets a slightly more understated one after, crying openly over the fact . Not as severe as some, but given Shizuru's graceful serenity over the entire series to that point, seeing her outright crying and apologizing through the tears had impact.
 * Yukino after she is blackmailed into . Even after the almost victim later thanks her for helping her find, she still feels quite guilty.
 * In Mai-Otome 0 Sifr, Elliot has this reaction after . After seeing her in tears over it, her companions forgive her, although.

 * In Papuwa, Kotaro says exactly this when.

 * Happens quite often in Detective Conan, probably the most memorable one being
 * Doctor Marcoh from Fullmetal Alchemist. Now that he's gone and, he feels horrible about it. With good reason. Also, most of the protagonists in the Ishbal arc of the manga. War suddenly doesn't seem so great anymore.
 * Edward Elric, in an attempt to bring his mother back to life, ends up losing his arm and leg and nearly bleeds to death, his brother's body is completely destroyed and he ends up as a soul in a suit of armor, and then he realizes all he managed to do was create a writhing mass of nightmare fuel instead of his mother.

 * When in the manga. Big No ensues.
 * Roy after.
 * In Higurashi no Naku Koro Ni, several of the characters have these moments. Heck, Keichi has two regarding the same horrific event.
 * Android Kikaider: The Animation (not to be confused with the live-action ancestor of the "Power Rangers.") In the first episode, Jiro (the android) helps some kids get their toy airplane out of a tree by pushing the tree over. (He was in his "human" form at the time, and the kids thought they were enlisting his help to climb the tree.) After the the kids run away, any humor in this moment gets a kick in the nuts when Jiro realizes there was a bird's nest in the tree, and the eggs in it have been destroyed. In the English dub, he utters the trope verbatim.
 * In the manga Pokémon Special, Ruby does this when he realizes

So when he says the trope's title out loud, the character making the offer responds "You have saved the lives of every living thing on this planet".

Fan Fiction

 * Katara has one of these in the Avatar: The Last Airbender fanfic The Chong Sheng Trilogy, after
 * In a Sonic the Hedgehog fanfic, Blast to the Past Princess Elise managed to prevent the Metarex from changing the past, (without Eggman, they'd have no competition, and most likely none of the events of the Sonic games would have never happened) but latter finds out - much to her shock and disgust -  something that was just as bad when   Silver and Blaze managed to convince her that Sonic played an important factor in everyone's lives,
 * In the Axis Powers Hetalia doujinshi Besame Mucho, Spain gets one of these (quoting the trope name included) when standing in front of a destroyed house in a village his army just slaugtered. He is passing by when he sees a dead child's arm peeking out of a pile of wreck, and it makes him remember about Romano. Something was in my eye when he says that they just killed people, who were the same as him or little Romano. His companion's answer? "You are wrong. You are not human.". Tear Jerker, indeed.

The fic starts after this moment; when it's not filling in backstory, it's detailing her attempts to atone for her actions.
 * Shinji, on the other hand, blames himself for everything Asuka has done to him, seeing his actions during the canon story (especially the hospital scene in Eo E) as so unforgivable that he can justify her abuse as karmic retribution.
 * In yet another Axis Powers Hetalia fanfiction 'Let me be Your Savior' Romano/Lovino has one after stumbling across his brother (Italy/Feliciano)  crying, and it finally hits him that what he's been doing is wrong. This scene is a nice breakthrough, seeing as Romano/Lovino had seemed to cross Moral Event Horizon before.

 * He also said "What have I done?" right after In both cases, it is followed not by any effort to Must Make Amends but instead by Jumping Off the Slippery Slope.
 * Matt Stover's Novelization wisely leaves out the Big No, adds a fleeting moment of Never My Fault, and rather than throwing a tantrum has him immediately try to kill Sidious--but he's lost so much of his power that he can only destroy droids and equipment, he can't even touch Sidious--and in the end he doesn't want to, because now this is all he has left.

Later on in the movie, Gilbert loses his cool - leading him to slap Arnie around, after being so protective of him.

 * Hilariously subverted in A Dog's Breakfast. Patrick wants to kill his future brother-in-law, Ryan. Ryan offers to help him chop wood by holding the wood steady for him. Patrick lifts his axe up, clearly intending to render Ryan in two. We cut to a shot of the woods just as we hear a dull thunk, complete with blood curdling scream.

 * Given what his ship means to just about everyone in Starfleet, and especially to Kirk himself, it's easy to argue yes. He's destroyed the one thing apart from his immediate crew that he actually loves.
 * Hilariously twisted around here by combining Kirk's lament with Too Dumb to Live.
 * Terminator 2 does this (but doesn't say it) to Sarah Connor. After spending the majority of the movie as a fundamentally screwed-up person, she tries to murder a man, not because of anything he's done, but based on what he will do in the future. Everything from her attitude during the "hunt" to the weapon she uses is eerily terrifyingly similar to the T-800's targeting of her in the original film. It's only when she's holding the gun to his head, in front of his terrified, sobbing wife and son, that she starts to realize exactly what her fear of the future has done to her.

He reads the name, realizing his mistake, and has Stern make sure the two are brought to the factory, presumably to start training in manufacturing before becoming full-fledged workers.

 * In the made-for-tv Elvis Meets Nixon, it's 1970, and Elvis has snuck out of Graceland, out on his own for the first time in over a decade. He has fond memories of LA's Sunset Strip, but when he gets there he's appalled to find it overrun with hippies and head shops where his records are back in the 'golden oldies' section. A hippie recognizes Elvis and excitedly tells how he changed his life - in an irony worthy of The Twilight Zone, he points out that Elvis's spirit of rebellion created the counterculture. Elvis is horrified.

 * Charles Dickens wasn't averse to this sort of twist. In Great Expectations, the malignant Miss Havisham gives us the following line: '"O!" she cried, despairingly. "What have I done! What have I done!"'
 * The Assassins of Tamurin: This is Lale's reaction after she kills her would-be mugger/rapist. What stresses her out is that she didn't kill him simply in self-defense but because she was excited to put her training to the test.
 * JRR Tolkien's Lord of the Rings: Boromir's moment, when he realizes how badly he screwed up by attempting to take the Ring from Frodo, leads directly to his Redemption Equals Death.
 * The Steward's family is big on these moments. Denethor has another when his younger son, Faramir, is brought back dying after being wounded in a pointless battle which Denethor sent him into.
 * This trope also turns up in JRR Tolkien's The Silmarillion. Turin has this reaction after he kills Beleg and Brandir. . His father Hurin has a similar reaction when he realises his attempts to avenge his family have only helped Morgoth.  . Maedhros has one when his attempt to get the Silmarils from King Dior leads to the deaths of Dior's two young sons, and he and his brother Maglor have an epic one later when they realise that all the evil they committed in the pursuit of the Silmarils was for nothing because, after all the evils they've committed in search of the Silmarils,.
 * Jo Walton's Ha'penny: Inspector Carmichael, after.
 * In Flag in Exile, Honor Harrington is attacked by an assassin who sees her as a corrupting agent of Satan... but the beloved leader of his church takes the bullet for her. Horrified, he drops the gun and falls to his knees: "My God, my God--what have You let me do?"

 * The end of Ender's Game sees Ender discovering that
 * In the book of Daniel, chapter 6, Darius, having taken over Babylon, is convinced to sign a decree that no one should petition any god or man other than the king for the next thirty days would be thrown into the den of lions. Daniel, who was the unspoken (at least to the king) target of the decree, heard about it, but continued to pray without making an attempt to hide it. The phrase is not recorded to have been said (it may have been "My gods," for all we know), but it does say he was "sore displeased with himself", and he tried to figure out a loophole or something until the architects of the decree reminded him that he couldn't change what he signed into law. (Of course, the lions end up not harming Daniel at all, and the king even said before they closed up the den that that would be the turnout, but the idea stands.)
 * Arguably Judas Iscariot's reaction after the crucifixion of Jesus Christ. He later hung himself or threw himself off a cliff out of guilt.
 * Judas really shouldn't beat himself up. After all, without the crucifixion there'd be no resurrection, and do you think Jesus didn't know that?
 * Peter betrayed Jesus too In a different way. However Judas never came back to seek forgiveness.
 * In James Swallow's Warhammer 40000 novel Deus Sanguinius, 's first words (after ) when he is Dying As Yourself. He is deeply moved by Rafen's Manly Tears, and while quite certain of his own damnation, begs Rafen's forgiveness.

 * In The Dark Elf Trilogy (the second book, Exile), Drizzt ponders on this when he starts to realize that living on the run all the time, constantly paranoid, has caused him to start to lose his humanity, especially after ; however, it isn't until Gwehywvar looks him in the eye that he starts to realize it and tries to find ways to regain said humanity... or elfmanity.
 * In Death Star, MCPO Tenn Graneet, chief gunner for the superlaser, is hit with the enormity of what he has done, and when he is called to fire on Yavin 4, desperately stalls for time.

 * The Dale Brown novel Act of War has Kelsey quite distraught after she realises that she had unwittingly ordered  to his death.
 * Edge of Battle has a US Army Humongous Mecha mobbed by rioters at a detention camp for illegal immigrants ("Jumping the shark"? Your Mileage May Vary) and reflexively responding with predictably horrific results. When he comes back to his senses the mecha's pilot calmly and methodically climbs down from his vehicle, picks up the first available firearm and puts a bullet through his head.
 * In Harry Potter and The Half Blood Prince, after Harry, panicking and about to be Crucio-ed by Draco, unwittingly tries out his new "Sectumsempra" spell for the first time in the bathroom. The result is Draco being slashed to bits. Whoops.
 * Also Severus Snape, after he realizes his actions have inadvertently sentenced a woman he loves to death. Whoops again.
 * And in the film version of Goblet of Fire, when Harry doesn't resurface from the Hogwarts Lake for a minute or so after being given his underwater breathing apparatus (Gillyweed), Neville gasps, "Oh my God- I've killed Harry Potter!" Harry then promptly does a spectacular backflip out of the water, making everybody know he's quite alright.
 * Ginny Weasley's attempt to destroy Riddle's diary in Chamber of Secrets was (probably) a reaction to this trope. In any case, she was in full mode of this trope after being saved by Harry at the end. Poor Ginny. It must be... devastating doesn't even describe it... for an eleven-year-old to realize her actions have very nearly caused the deaths of half her friends and her crush. Maybe that's why she was so sympathetic to Harry after the "Sectumsempra" incident.
 * was this for Dumbledore.
 * In Cry Mercy, the third volume of Toni Andrews's "Mercy Hollings" series, the title character confronts her adoptive parents in order to seek answers about her mysterious origins and troubled childhood. Throughout the series, she has expressed a great deal of anger towards her adoptive parents for dissolving the adoption and giving her back as a ward of the state at the age of twelve, which led her to spend her teenage years in a series of unhappy foster homes. She believes they abandoned her because they couldn't deal with the fact that she was a psychic with the power of Compelling Voice. However, her former adoptive mother reveals that . She had repressed the memories of what had really happened, and realizes later that she is at least partly responsible for the problems that have made her miserable all her life. Mercy has another moment like this later on when trying to get an armed gunman to put down his weapon and release his hostage. She does not have perfect control of her power, and when he fails to respond at first she
 * Warrior Cats: Lionblaze does this a lot in the latter half of Power of Three, usually after he loses control of himself, or during one of his homicidal Nightmare Dreams.
 * The Poisonwood Bible: Nathan, after due to his desire for a dramatic conversion of the village.
 * In Adventures of Huckleberry Finn, Jim strikes a little girl for not listening to him when he told her to close the door. It turns out she couldn't listen at all. She was deaf.
 * In The Wheel of Time, Rand has one.
 * In John C Wright's The Golden Age, Helion tells Phaethon his origin: he had been a character in a scenario who destroyed a planet. His My God What Have I Done reaction caused him to brood over questions of existence, and the brooding caused him to become a self-aware personality, no longer just a character.
 * In Aaron Allston's Galatea in 2 D, the hero tortures one of the villain's mooks to try to get information from another. He slackens off without getting everything he wanted, realizing that she didn't know anything and that he was invoking What Measure Is a Mook. That thought horrifies him -- just because they were two paintings who came to life, and whom the villain had sent to kill him didn't mean torturing them was all right.
 * Appears near the end of Jean De Florette for Papet.
 * Actually this comes at the end of Manon Des Sources, if you want to be picky. The ending of Jean De Florette is more.
 * "Almighty God! Enough! Enough!"
 * CS Lewis observed that Jane Austen loves to have characters suffer a dramatic, emotionally devastating disillusionment where they realize how blind and misguided they've been about a certain topic:
 * Northanger Abbey: Catherine Moreland experiences this trope when she realizes This Is Reality, and she's been foolish to view the world and people through the lens of Gothic fiction.
 * Sense and Sensibility: Marianne experiences this trope when she regrets the excess of Emo Wangst that almost killed her.
 * Pride and Prejudice: Elizabeth's turn comes when she reads Mr. Darcy's letter and realizes how flawed her judgment of Mr. Darcy and Mr. Wickham has been and that she herself is guilty in this area of the pride and vanity she so abhors.
 * Mansfield Park: Sir Thomas (the heroine's uncle) deeply regrets how he raised his daughters to be spoiled, vain, Brainless Beauties and what a stern, cold father he was when he sees the effects such an education has had on them.
 * Emma: Emma is horrified over the mischief and pain her matchmaking efforts cause.
 * Persuasion provides a subversion (in the correct use of the term): Near the beginning, Anne looks back with regret on breaking her engagement to Captain Wentworth, but the book ends with her realizing she was wrong and deciding I Regret Nothing. Captain Wentworth himself plays it straight when he realizes what a mistake he made never coming back to ask Anne to marry him again after he began to make his fortune.
 * Non-lethal/non-romantic example: A widower-turned-priest in the Brother Cadfael series spent an entire novel trying to marry off his daughter to a man she didn't even like, because he thought that having her around would hinder his advancement in the clergy. Eventually she runs off to Dublin with a Danish youth to escape the Arranged Marriage; hearing this, her father contentedly proclaims that he'll never see her again ... and then pauses, and says it again in tones of grief, as the belated realization that he'd loved and will miss her hits home.
 * Susan's aunt from Wizard And Glass may have died of this trope, as it's speculated that her fatal heart attack occurs when she comes out of her enraged trance and realizes that.
 * In Over the Wine Dark Sea Sostratos tells Menedemos a story of a Pancrationist(one of the nastiest combat sports invented) in Athens who kills his opponent (a very easy thing to do in Pancration) and goes mad with rage because of it.
 * In Adrian Tchaikovsky's Dragonfly Falling, Fenise asks "What have I done?" as she realizes why she won't kill Thalric.
 * In L. Jagi Lamplighter's Prospero Lost, Miranda leads a boat that is pursuing hers on a route that ends with his crashing and dying. In Prospero In Hell, she learns he wasn't an enemy. Nearly has Tears of Remorse.
 * Discworld: Carrot has one of these moments in Men At Arms. He spends the night with Angua, and wakes to find . She runs away, and shortly after Carrot finds out exactly what just happened, he realizes that the first thing he did when he saw   was reach for his sword.
 * Jean Valjean of Les Misérables has a Heroic Blue Screen of Death based on this trope after he robbed a child. The robbing happened right after his encounter with Bishop Myriel, who gave him a second chance at freedom after Valjean betrayed the Bishop's trust and robbed from him. The combination of these two events cause a guilt trip several pages long.
 * Tsion Ben-Judah's reaction in in the Left Behind book Desecration when he realizes he has given away the location of where the Israeli Jews would flee to according to what the Book of Revelation says about the matter (the deserted city of Petra), fearing that he has messed up God's plan. He gets some reassurance from one of the Tribulation Force members that God may have intended for Tsion to let slip the location of where the Jews would flee to in order to lure Nicolae Carpathia's forces into a trap God has set up for them, which is all according to the Word of God.
 * In Septimus Heap, Marcia has this reaction after she accidentally Banishes Alther to the Darke Halls in Darke.
 * Elizabeth Bathory goes through this in Count and Countess when she realizes bathing in blood is not curing her epilepsy, and she has been killing young girls for no reason at all.
 * Stephen Fry's The Stars' Tennis Balls has its vengeance-obsessed hero break free of his island prison and return to Britain to pursue a drawn-out violent campaign against those whom he sees responsible. After various horrific killings, he looks forward to reuniting with his college sweetheart. But she knows what he's done. The close of the book has him voluntarily returning to the prison he escaped, in all likelihood to stay there until he dies.
 * The concentration camp commander in The Boy in The Striped Pyjamas.
 * Rick Deckard, the protagonist of Do Androids Dream Of Electric Sheep, is a Bounty Hunter tasked with killing androids who are posing as humans. He gets one of these moments midway through the book, after eliminating an android who had been working as an opera singer, and had earlier moved him with a song. He is ashamed that he has destroyed something beautiful and, on another level, worried about what this newfound empathy for his prey says about him.
 * John realizes too late that leading his people to war was entirely the wrong thing to do in Dirge for Prester John. They are unable to grasp the concept of war, or even the death that accompanies it, and treat it almost like a kind of game. This ends tragically.

Live-Action TV
"Spike: "What have I done? ... Why didn't I do it?""
 * Cheers. Carla once asked Frasier: "When you and Lilith wake up in the morning, which one of you is the first to scream, 'My God, what have I done?!'"
 * In another episode, this is essentially Fraiser's reaction upon fully realizing that he has successfully launched Woody Boyd's political career. (Cue visions of atomic fireballs.)
 * On Buffy the Vampire Slayer and Angel, Faith does this twice. First when she accidentally kills Alan Finch, screaming repeatedly "I didn't know!", and when she remembers what she did to Wesley and Buffy.
 * This is also plainly evident in Willow's expression in "Once More With Feeling" when Buffy lets the Scoobies know that when they brought her back to life
 * Spike after the Attempted Rape in "Seeing Red". In a rather disturbing take on the trope, he seemed almost as distressed about his inability to go through with the act as he was by the fact he attempted it at all.

"Londo: He said... That we are both damned."
 * Angel after the gypsy curse personifies this trope. Without a soul he was a Complete Monster, and he now believes he has to atone for what he has done.
 * On the Angel end is Gunn's epic version of this after his part in .'
 * And Wes's equally epic one after he went literally Ax Crazy in "Billy". He was under a spell, but it didn't matter, he still hated himself.
 * Wes also had one after he shot what he thought was his father in "Lineage".
 * Face's expression after he pushes Murdock to the ground during their fight in Family Reunion borders on this. It's kind of a combination "What did I just do?" and confusion over the fact that Murdock doesn't seem the least bit angry with him for doing it.
 * Arrested Development uses a variation of this, "I've made a huge mistake". The phrase is used for comedic value, though. It was first said by GOB in "Key Decisions", and used by various characters afterwards, although it does remain primarily GOB's catchphrase, as he uses it at some point in most episodes.
 * In Babylon 5, Londo has several moments of serious regret as his schemes to restore Centauri power and glory play out... though that doesn't prevent him from going through with them.
 * 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 approaches Londo in good spirits, extending a tentative hand of friendship. The problem: . The look on Londo's face as he realizes his mistake is Tear Jerking.
 * Londo gets a lot of these moments. In the same episode, when, Londo tells him how . whispers his last words to Londo. Londo tells the other Centauri present that  told him that he would want them to continue, and to "carry my people back to the stars". But what did he really say?

"(The wormhole weapon has been fired, and threatens to consume the entire universe.)
 * Another instance of this happening to Londo (Seeing a pattern?) made it into latter season's credits, with Londo watching the
 * Also in that show is Delenn upon watching Dukhat die after being attacked by Earth Alliance warships orders their immediate destruction. "NO MERCY!"
 * had been struggling with his Subordinate Excuse for five seasons and finally gets his chance when . He walks away, only to realize what he's doing moments later and runs back to.
 * 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.
 * I Carly: 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.
 * Carly went into a breakdown of repentance in iChristmas when her wish turned her life into one she did not want.
 * 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?!"
 * The Carpenter has one in the Sy Fy miniseries Alice, right after  then realizing it's a problem that he's spent the last ten years of his life sucking emotion juice out of people.
 * A 'My God, what have YOU done' moment happens at the end of the Peacekeeper Wars in Farscape. For four years people have been chasing John Crichton, killing, raping and attacking him and his friends for his wormhole knowledge, and he finally gives in and builds the thing to protect his wife and newborn child, and it turns out that wormhole weapons he's been telling everyone are horrific, galaxy destroying weapons that no one should ever have under any circumstances are actually just as bad as he always said they were. When he turns it on, even those most desperate to have them realise just how bad it is.
 * A quote is in order.

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."

Chiana: Crichton, can you stop it?

Crichton: I don't know, Pip. Maybe it eats the whole galaxy, a monumental black hole, a giant whirling headstone marking the spot where we all used to live and play and slaughter the innocent.

Scorpius: (softly) This is insane, Crichton.

(John lets out a choked laugh.)

Crichton: God! Four years on and you're finally getting that!"

"I think I may have made a big mistake! All of the sudden I realized what the problem is! I can't be with someone like me! I hate myself!"
 * A far more literal example is when Crichton has been forced to  In this case, Crichton really does say "My God, what have I done?"
 * Jerry Seinfeld, after he gets engaged to Jeanie Steinem, a woman exactly like him...


 * In Battlestar Galactica Reimagined, Gaeta, during the

""There should have been another way.""
 * Don't forget Caprica Six, who realizes after her first resurrection that the Destruction of the Colonies was a huge mistake, and spends the rest of the series trying to make up for it.
 * And Sharon (Boomer).
 * And Baltar, when he learns that he gave the Cylons information that helped them to kill billions of people.
 * Let's not forget the original My God What Have I Done moment, when Boomer finally 'regains consciousness' and sees the aftermath of her actions in the Season 1 finale. And the thematic continuation, the Season 4 premiere has.
 * Doctor Who:
 * The Fifth Doctor had a few of these moments. Notably, check out Warriors of the Deep.

"Chappelle: I'm like, you can't say skeet on the radio! You know what's so dope about skeet? White people don't know what it means yet. When they figure it out, they'll be like My God, what have we DONE?!"
 * The Ninth Doctor had one of these in "The Parting of the Ways", when he forcibly sends Rose back to her own time in the TARDIS to protect her from the Daleks,
 * The Ninth Doctor also had one of these in the previous episode, Bad Wolf, where he looks down on a ruined Earth, populated by people who do nothing but watch horrific game shows and realises that it all happened due to his actions earlier in the series.
 * The Tenth Doctor had one in "The Waters of Mars".
 * The Eleventh Doctor had one in "The God Complex".
 * Parodied on Chappelles Show: after one of the "Moments in the Life of Little Jon", Chappelle goes off on a tangent about the rapper's song "Get Low", which contains the lyrics "Aw skeet skeet skeet skeet skeet skeet!" He said the following:


 * Curtis from sci-fi drama Misfits can sporadically turn back time and re-play certain events from his past whenever he has one of these moments. Of course, it doesn't always work out for the best.
 * Kat from Power Rangers, when Rita's spell over her broke and she realized everything that she'd done to Kimberly.
 * In the first season Tommy has one immediately after Rita's spell is broken. It is probably Justified because he should be going into shock.
 * On Glee,  Will has a silent version of this, after a mild What the Hell Hero from Kurt.
 * In the 1998 Merlin series, Arthur has this reaction after Merlin calls him out for sleeping with Lady Marie, who was actually his half-sister. In the novelizations, this was taken up to full-blown Heroic BSOD that lasted for years.
 * In the Merlin series, Arthur goes into this trope after killing a captured rival king in "His Father's Son".
 * 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.
 * Michael from Prison Break wonders this for having (indirectly) lead to several deaths.
 * In an episode of Strong Medicine, 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. It was especially notable because Lu was a textbook Jerk Sue and Canon Sue, so seeing her beliefs backfire was unique.
 * In Lost, Jack has this reaction after finally
 * "We have to go back!"
 * In an episode of Star Trek Voyager, Torres utters this exact line when she realizes the race of robots she is helping were responsible for the extinction of their creators.
 * In The Closer, after several episodes of not feeling any remorse for facilitating a Vigilante Execution the previous season and not taking the victim's family's lawsuit against the department seriously, Brenda finally breaks down sobbing "What Have I Done?" at the end of season 7 episode 5, after everyone in her unit, plus Chief Pope, Commander Taylor, and her husband are all subpoenaed.
 * On the third-season finale of The Big Bang Theory, Howard and Raj make an account for Sheldon on an online dating site. Sheldon gets matched with Amy Farrah Fowler, who is almost exactly like him. Howard's reaction when he sees the two together: "Good God, what have we done?"
 * Forever Knight's Nick Knight has several of these over the course of the series, many in the flashbacks where he's struggling between needing to feed to survive and not wanting to kill.
 * Brass had one on CSI "Genetic Disorder", after spending the entire ep assuming Doc's wife really had cheated on him.
 * Duncan on Highlander after he
 * In Season 4 of Heroes, Samuel has this reaction after He may or may not quote this trope by name, as Robert Knepper's well-done emotional performance makes it unclear whether he's saying "What have I done", or if he's begging  to "Hold on".
 * In the Charmed episode "We're Off to See the Wizard", Phoebe utters this almost verbatim after using pyrokinesis -- an upper-level demonic power -- on Cole's new personal assistant.
 * In Mash, Father Mulcahey once impulsively punched out an unruly patient who hit him first during triage, when any delays in the selection process can cost lives. While the rest of the staff agree he was entitled, Father Mulcahey was kicking himself for some time afterward.
 * Hawkeye has this in the episode "Fallen Idol." He sends Radar to Seoul to "sew a few wild oats", and Radar subsequently gets wounded by enemy fire en route.
 * In the episode "O.R.", Frank Burns complains out loud about the difficulty he's having removing a wounded GI's kidney. On a hunch, Trapper goes over to look at the patient's x-ray...and shows Frank that the guy only has one kidney. While Frank's borderline incompetence in surgery was usually Played for Laughs on the show, in this instance he's shown to be genuinely shaken at the realization that he could have killed the man through his carelessness.

Music
" You cried "wolf" / the tears they soaked your fur / the blood dripped from your fangs. / You said "What have I done?""
 * Relient K's "Deathbed" lampshades this. The narrator is on his deathbed and recounting his life and all the mistakes he made. Including a shot-gun wedding, a love-less marriage that ended in divorce, a few kids that are implied to not see him much after said divorce, and a drinking problem that nearly kills him at one point. At the end Jesus appears to take the narrator to heaven because he repented heavily in his last few years.

"Reese Roper: You may notice that we are not rock stars, because you will hear these mess-ups and you will say to yourself, "My God, what have I done? What have I done?!" Oh, yes, you will."
 * On their first live album, Five Iron Frenzy prefaces a hidden track of Hilarious Outtakes with an introduction from the singer, containing the line:

"Out of control in this deadly machine
 * "The Ballad Of You Know Who" by Richard Swift deserves mention, for using this phrase as the entire chorus of the song.
 * "Once In A Lifetime" by Talking Heads quotes the trope-naming phrase verbatim.
 * Iron Maiden's "Killers" contains the line "Oh god help me what have I done?". As the song points out "his blood lust defies all his needs", meaning that killing people is what turns him on. Even though he regrets it, he can't stop doing it.
 * Iron Savior, of (unsurprisingly,) Iron Savior has one of these, touched on in a few songs. "I've Been To Hell";

Innocent victims are haunting my dreams"

"Built and designed to obey, to keep Man alive

 * Similar to the "Handlebars" mention above: Zero Sum, the final song on Nine Inch Nails' album "Year Zero" is basically one last humble apology from humanity to everyone who was hurt by the dystopian government that was allowed to come into power in the first place. All while the world quietly ends in the background.

"Disapprobation, but what have I done
 * Criminally Insane by Slayer.

"What have I done?
 * "Evaporated" by Ben Folds Five uses this line as the last line of the chorus - though it's never actually revealed what the singer actually has done.
 * Forgive Durden's musical, Razias Shadow uses this trope in a near-verbatim manner at the conclusion of "Toba the Tura," when.

Please make me your son

What have I become?

""Oh, what have I done, Lord? "

It's all my fault, the blood is on my hands!"

"But oh, what have I done? What have I done?
 * In the song "In the Glass" by OK Go, the protagonist immediately regrets his decision to become his reflection.

My God, what have I done?"


 * Tarby wrote a 20 minute My Little Pony song based on the fanfic that shall not be named. Pinkie Pie goes through this after.
 * Though you'll never hear these words in The Wall, the songs "Hey You" and "Stop" serve this purpose. In the first instance, he realizes exactly what he's done by completing the wall; in the second, he's horrified by what he's turned into.

When her son Hyllus arrives to blame her for killing dear old dad in the most painful way possible, she really loses it.
 * Jean Valjean's soliloquy after being saved by the Bishop in the musical adaptation of Les Misérables begins with almost exactly this line. "What have I done, sweet Jesus what have I done? Become a thief in the night, become a dog on the run? Have I fallen so far, and is the hour so late, that nothing remains but the cry of my hate?" Valjean goes on to explain that after a lifetime of being convinced that he was worthless and the world pitiless, he has met a man who is truly good and selfless, and robbed him, to receive no punishment.
 * A rather more poignant example comes from

 * Link from The Legend of Zelda Ocarina of Time. He pulls the Master Sword out of its pedestal, not knowing Ganondorf was using him to get into the Sacred Realm. Especially hits home when you visit what used to be Hyrule Castle. Link's expression can only be, "Oh my God, I did this."
 * Alexandra Roivas from Eternal Darkness, at the end of the game. After you defeat Pious Augustus, Alexandra finally realizes the Except not really, because it's revealed through one hell of a Mind Screw that
 * Richter Belmont screams this once he's freed from being Brainwashed and Crazy, since he's inadvertently helped resurrect Dracula once again.
 * In Dragon Quest VIII, Dominico is said to be a descendant of one of the seven sages that sealed Rhapthorne away, and indeed, he appears to be a target of the possessed . However, it turns out that . When, Dominico discovered it had been his duty to protect David, and pulls this trope when he realized he failed that duty miserably.
 * Arguably, Niko Bellic in Grand Theft Auto IV.
 * In in Soul Nomad and The World Eaters,  gets the evil slapped out of him and reverts to his prior personality... With the first thing that strikes him is all the gruesome things he has been doing in the meantime.
 * in Persona 4 goes through this after being told that he was endangering lives by throwing people into the TVs rather than saving them as he thought. Of course that is if you didn't choose to throw HIM into the TV as an unfair version of the Karmic Death.
 * Kratos, the protagonist of God of War, demonstrates this trope upon Whether or not he actually learns from the experience and becomes a better person for it is a matter of debate.
 * Happens again in God of War II. At the end when you're  Kratos is distraught by this. Happens again in God of War III when Kratos gets so fucking pissed at Zeus he lets go of Pandora whom he was trying to save from getting destroyed from the flame.
 * Neku Sakuraba from The World Ends With You, when he realizes that not only was.
 * Cecil and Kain, after unintentionally helping to destroy the village of Mist, in Final Fantasy IV.

 * Happens at the very first event of Indigo Prophecy, the main character, after coming to his sense, realized that he is holding a knife, blood dripping from his clothes, and a dead man lying right next to his feet, stabbed many wounds to the chest.
 * This is a subtext of the game Shadow of the Colossus. Any time the protagonist kills one of the Colossi  Many people felt exactly My God What Have I Done after they killed the thirteenth Colossus, specifically: a majestic creature that doesn't attack, can barely defend itself, and doesn't even approach the player in any way.
 * Similar to Shadow of the Colossus, Far Cry 2 seems to be designed to eat away at the player until they realise just how many people they're butchering and what a monster they are, resulting in a My God, What am I doing? moment.
 * Kastor in Age of Mythology, after.
 * Oichi from Sengoku Basara, after
 * In the Ulduar raid of World of Warcraft, Algalon the Observer is sent by the Titans to "re-originate" the planet (read: destroy all organic life) in the event the corruption from the Old Gods got too severe - actually triggered by your earlier murder of one of the Titans' corrupted overseers. However, if your raid manages to defeat him, he has one of these moments, in which he laments just coldly following his orders without considering the lives of the people he was destroying.
 * In a more humorous example, in The Nameless Mod, Despot says this when he tells the player that he left Ghandaiah in charge instead of the far more competent King Kashue.
 * In Jet Force Gemini, King Jeff heads to planet Tawfret to give some more of his people the good news that Mizar's defeat may be at hand... only to see them getting rounded up into slave ships by Mizar's soldiers. He lets his emotions run out of control, and the resulting magical asskicking becomes decidedly not awesome when it zombifies the entire planet and most of the soldiers on it.
 * Charles Barkley's feelings toward the chaos dunk he performed that killed thousands if not millions and led to the genocide of b-ballers in Barkley Shut Up and Jam Gaiden.
 * The Paragon Caridin in Dragon Age Origins . He initially justified this with the increasingly desperate war against the Darkspawn  . But when the King (the only one in Dwarven society whose opinion trumps a Paragon's) Jumped Off the Slippery Slope   and Caridin protested, the King  . After   Caridin realized he had done something unforgivable and dedicated himself to.
 * Can also happen with the Paragon Branka, who led everyone in her house to horrible deaths in the Deep Roads on her mad quest for the Anvil of the Void, and allowed the Darkspawn to rape some of the women and turn them into Broodmothers. If the Warden sides with her during the initial dialogue with Caridin, which leads to being forced to kill him, in the conversation with her after the fight she can be persuaded to see the Anvil for the abomination it is, and to see all of the pain, suffering, and damage her maniacal desire for it has caused. If successful, it will cause her being so overcome with guilt that it drives her to commit suicide by leaping into the lava.
 * Adrienne in Phantasmagoria didn't actually say the line, but her "What have I done?" moment happened when she realized that  was the direct result of   at the beginning of the game. Oops.
 * In Mass Effect 2, Mordin Solus was left guilt-ridden by his work in . While he felt that what he did was necessary, it didn't mean he had to like it and forced himself to make anual trips to check on it since he felt that simply walking away would be wrong. In order to better atone, he became a doctor/borderline vigilante in the Omega space station.
 * Subverted, however: he says repeatedly that he would choose to do the same thing, and that he doesn't regret what he did. He felt it was necessary; however, he chooses to always remind himself of the price paid..
 * Two other Salarians involved in the project, from the second game and  from the third, both eventually come to the conclusion that their work was unethical. Unfortunately, the former ends up falling even further down the slippery slope when he tries to reverse his handiwork.
 * from the "Project Overlord" DLC eventually has this reaction to
 * In Mass Effect 3, if you can make realize that he's being indoctrinated by the Reapers,
 * Miranda Lawson is an interesting variation as her's is more, "My god, what did I ALMOST do?" Her hatred of her father comes from the fact that he tried to control her and her sister, make them slaves to do whatever he wanted them to do. She almost did this to Shepard, when she attempted to plant a control chip into his/her brain while bringing him/her back to life. By Mass Effect 3, she realizes this and feels unbearable guilt, telling Shepard how sorry she is for even considering it.
 * A close variant of this phrase serves as the opening tagline of Dark Fall: The Journal.
 * Amazed no one has mentioned Zero's epic meltdown in Mega Man X 4 after his defeat of . "What am I fighting foooooooor?!?!?!"
 * In Pokémon Ruby and Sapphire and Emerald, Maxie and/or Archie (depending on your version) come(s) to realize what he's brought upon the land when they use the Blue or Red Orb to awaken Groudon or Kyogre, respectively, as their intense sunlight or rain begins to spread throughout Hoenn (storywise, anyway, as weather effects were not seen in the overworld of places such as Littleroot Town during the Weather Trio crisis).
 * Admiral DuGalle, after.
 * In World of Warcraft Cataclysm,  has this reaction after
 * Super Metroid even has a few of these moments. After fighting a big Metroid, it runs off in shame once it realizes
 * Happens again the Crocomire, who suffers a nasty death hardly fitting it that can only make the player feel sorry for it.  Honestly, even the game designers felt the moment was worth a What the Hell Hero.
 * In Assassin's Creed 2, some of the lieutenants of Savonarola have this reaction after Ezio fatally wounds them.
 * does this in Persona 3, although in his case it's less "My God What Have I Done" than
 * Star Ocean 4:
 * from Kingdom Hearts Birth By Sleep has this reaction after
 * At the end of Etna Mode in DisgaeaAfternoonOfDarkness,.
 * has this reaction in Dragon Age II right after if he is a full rival. After the most recent patch, he can even be convinced to  to help mitigate the damage to Kirkwall.
 * In Tactics Ogre, some of the leaders' death quotes might invoke this to the player. You kill a person who seems to just be a named Mook...then an optional battle (If you wanna recruit one of the characters) has a woman who wants revenge because you killed her husband. After you beat her, she reveals she's pregnant. Another person laments that he won't be able to get medicine for his sick daughter.
 * The PSP version also has a wizard who fights you in chapter two who wants revenge on Denam. What for? A boss you fought in chapter one was his twin brother.
 * Raiden has a massive My God What Have I Done moment in Mortal Kombat 9,.
 * King Volechek in Golden Sun Dark Dawn has this moment. When he realizes the ancient tower he got the heroes to reactivate was really going to cause an eclipse that summoned hoards of monsters on half of the globe. Did we mention his kingdom was in the middle of it?
 * And in the game before that, The Lost Age,
 * In Tales of Symphonia, Yggdrasil has a BSOD of the none-heroic variety when asks him this very question.
 * Also, in Tales of the Abyss, when Luke realizes he's . Pretty much the rest of the game is affected by this moment.

 * Lara Croft in Tomb Raider Anniversary has this moment when she is forced to kill Larson, who held her at gunpoint. It was Lara's first human kill in her whole life.
 * in Nie R goes through this in Endings C & D over
 * In the Fallout New Vegas DLC Old World Blues, it's possible to get Evilutionary Biologist Dr. Borous to feel intense guilt over his brutal experimentation of his loyal dog Gabe after you bring him his food dish. Of course, he quickly forces himself to suppress the feeling and goes back to his obsession with Science!

 * In the prequel book Start of Darkness, Redcloak goes through a more tragic use of this trope after he.

 * Vaarsuvius's expression upon realizing  is the non-verbal epitome of this trope. V has a verbal one in the next strip at the discovery of

 * Pibgorn Pib. . . What have I done? (Why, lost Pib in the upper atmosphere when you need her help to save the earth.)
 * Vriska in Homestuck goes through this when she realizes that

Web Originals
"She flew back, bounced on the roof once, went over the side of the building bonelessly. Yelped when she hit the pavement in the alley. Yelped like a wounded puppy."
 * Chrome Cobra in the Metro City Chronicles gets one after beating up a temporarily insane Shapeshifting comrade.


 * Oran from Broken Saints says this after he attacks his childhood friend Hassan in a cabin fever-induced madness.
 * This has a tendency to crop up in Survival of the Fittest, usually when a 'hero' character kills somebody. An example of this is Julie Mikan after killing Owen Fontaine, going into a Heroic BSOD simultaneously at the relisation that she has actually ended somebody's life.
 * Slightly subverted in the Gaia Online plot: 247 says the line after killing 013, but before he knows the full consequences of his action.
 * Played a bit more straight when the Jerkass Corrupt Corporate Executive William F. Drink finally sees the mass chaos for himself and realizes he should have listened to his son all those years ago about the chemical byproduct that trapped the ghosts in their graves and drove them insane.
 * In Dragonball Z Abridged, Dr. Briefs yells "WHAT HAS SCIENCE DONE??" after Goku blasts himself into space on a ship Dr. Briefs built.
 * King Kai gets one too, after realizing that sending Goku home has resulted in him being all alone again. When Bubbles, Gregory and Bojack try to comfort him, he tells them to shut up.
 * In Doctor Horribles Sing Along Blog, Villain Protagonist Dr. Horrible has one of these moments as he kneels over the body of his would-be Love Interest, Penny, the innocent victim of his exploding Death Ray. The closing song, "Everything You Ever", is both a celebration of his triumphant victory and a dirge for his lost hope.
 * The Nostalgia Critic is pretty broken up about shooting his childhood icon, Mary Poppins, when she didn't explain all the Plot Holes in Quest for Camelot.
 * He looked crushed in Kickassia right after he accidentally shoots.
 * She'd never admit it verbally, but The Nostalgia Chick draped her dead BFF's Star Trek shirt over a nearby chair in guilty memorial of the Kirk vs. Picard fight that got her killed.
 * Avatar the Abridged Series- When Sokka rails against the Inventor, saying he's a traitor TO SCIENCE! because he is responsible for all of the "Steampunk Nonsense" in the Avatar world, the Inventor tries to defend his claim, saying that steampunk stuff could work and runs on scientific principles. Sokka cuts him off again, mentioning steam-powered jetskis. This leads to the Inventor having a Heroic BSOD while saying the trope word for word at the "horror" he has perpetrated against the world.
 * Ayla from the Whateley Universe has a bad case of this when after fighting a demon and being taken away, held and questioned by the anti-mutant police, he discovers that the MCO really do send mutants away to be dissected, studied and killed. Given that Ayla used to be Trevor Goodkind, a member of one of the world's richest and most powerful families, and that in some years he donated more to the MCO than some countries, he was indirectly sponsoring the murder of innocents. While a lot of his friends tell him that it's not his fault and he couldn't have known, the principal tells him that even though sponsoring a legal organisation isn't illegal, by her estimate, the MCO are guilty of 90% of the disappearances, and what happened to the other 10% of the children is probably even worse.
 * Played for Laughs in the "Cake" segment of the first asdfmovie.

Western Animation
"Bugs: WHAT AM I DOING???!!"
 * In an episode of Angry Beavers, Norbert delivers this line in a neutral, almost bored, tone.
 * One of the best known examples is in the Looney Tunes short, "What's Opera Doc" where Elmer Fudd, after spending the whole short exhorting in Wagnerian time that he would "Kill the Wabbit!", laments what he's done after he does it. (He also does this in some other shorts, but this was the most recognizable instance.)
 * The World of Warcraft Fan Vid Red Snapper starts in a short parody of this, with the line (sung): "What have I done? I've killed a wabbit......" (spoken) "Oh, well."
 * This goes back to the very first Bugs short, "A Wild Hare", in which he shoots at Bugs and then Bugs plays dead, causing Elmer to break down in tears and call himself a murderer.
 * Which asks the question of why does Elmer even go hunting?
 * It could be that Bugs' "death" scene is played out with so much gusto and pathos that Elmer is left feeling ultimately guilty.
 * The dog in "Hare Ribbin'" does this after he takes a bite of the rigged "rabbit sandwich" Bugs makes for him and Bugs plays out his "death" scene.
 * Bugs himself zig-zags this in "Hare Force" as he almost takes the Gremlin's mallet to a blockbuster bomb.

"Professor: Ohhh, you've killed me! You've killed me!
 * Parodied in Futurama, in one of the "Anthology of Interest" episodes, wherein Leela kills the professor by pushing him into a pit of man-eating anteaters:

Leela: Oh God, what have I done?

Professor: I just told you; you've killed me!"

"*Sad violin solo* Zoidberg: What have I DOOONE!!!"
 * Also played straight after framing Fry in destroying a bottle-ship in the episode "30% Iron Chef":

"Bender: Oh, what have I done?
 * And when Leela has to hunt penguins due to severe overpopulation. After firing into a crowd of penguins, she freaks out.
 * The Movie/Miniseries "Bender's Big Score", when Bender . It screws him up that he manages to regret it rather emotionally despite
 * Happens again in the second installment "Bender's Game", where Leela kills an Eldritch Abomination incarnation of Zoidberg under the belief he is an evil monster, only to learn he is not and swears off violence for a portion of the film.
 * Played with again in "Jurassic Bark", after Bender throws the fossiled dog into a lava pit:

Zoidberg: You didn't do anything, don't beat yourself up."

""What have I...what have they done to you?!""
 * Dragon Booster: While it did not happen in show due to cancellation, fans on the offical forum all agreed that they exlicity did not want Moordryd's obviously-going-to-happen Heel Face Turn to include a situation where he said "What have I done" in any way shape or form. Since the series was Screwed By the Network, we'll never know, but he seemed to be shaping up to be able to do without it.
 * In the episode "Fatherklok" of Metalocalypse, Skwisgaar says this after pushing his stepfather in a fit of rage and causing him to hit a coffee table - it breaks underneath him, and he groans in agony as he looks at the shards of glass embedded in his hand.
 * Family Guy takes a peg from Arrested Development, after Stewie sends away a babysitter who possibly could've been his soulmate.
 * Played for laughs in "The Kiss Seen Around the World" where Chris says this almost word-for-word after saying "poo".
 * Memorably subverted twice in Gargoyles first by Demona and later by John Canmore.

"Homer: What have I done? What have I done???
 * Talon gets this after becoming an Unwitting Pawn to Xanatos.
 * Xanatos himself has such a moment when he realizes in horror what he unleashed in creating Thailog from his Machiavellian smarts and Goliath's brawn.
 * Subverted in the pilot episode of Aqua Teen Hunger Force. After the Rabbot that he personally built escapes and goes on a rampage, Dr. Weird dramatically exclaims "What has science done?!" Also played straight by Frylock in the episode "Super Birthday Snake". (And yes, this is the source of the internet-popular quote, "What Has Science Done?!")
 * Parodied in The Simpsons episode "Simpsons Tall Tales". In a retelling of the Johnny Appleseed story, Homer realizes he singlehandedly hunted the buffalo (their main food source) to extinction:

Bart: Dad! Look! There's still two left!

[Whip Pan over to two buffaloes who are promptly shot dead]

Homer: (holding a still smoking shotgun): What have I done? What have I done???"

"Homer: Oh no! What have I done? I smashed open my little boy's piggy bank, and for what? A few measly cents, not even enough to buy one beer. Wait a minute, lemme count and make sure... not even close."
 * Also parodied in "Homer's Odyssey", when he steals and breaks open Bart's piggy bank for beer money:

"Homer: What have I done?! What am I doing?! What will I do?!"
 * Parodied again.

""Is that...me?""
 * Sheen in the Jimmy Neutron episode "Sheen's Brain" after
 * Another example (although not word-for-word) is when Jimmy himself (accidentally) becomes a hall monitor in "Hall Monster". He goes...a little OTT, to say the least. As in, locking people IN CAGES in detention, OTT.

"Brain: What have I done? Pinky! Are you all right?
 * In one episode of Pinky and The Brain, the Brain starts to realize that he has a problem when he goes a little crazy and accidentally pushes Pinky off of the table (or whatever it is that they're on):

Pinky: Uh huh. Narf! But I'm afraid my secret playhouse will never be the same... (he had landed on top of it.)

Brain: Oh, it's all my fault. This obsession with taking over the world is causing me to hurt the ones I... tolerate."

"Dark Heart: What...have I... done?"
 * This event prompts Brain to go to an organization called Megalomaniacs Anonymous in an attempt to get over his obsession with world domination. In a subversion, he decides in the end to return to his quest, since it's actually "a mission of mercy" -- if he ruled the world, it would be a better place for everyone.
 * This ties in with a subdued, implied Mind Screw of the series:.
 * An episode of Batman the Animated Series features a robot clone of Batman that seeks to kill Batman and take his place. Once he (apparently) succeeds at this, he goes through an existential crisis since the real Batman wouldn't kill anyone. He cries out "What have I done? I've taken a life!" and proceeds to smash the console evil supercomputer HARDAC was attempting to use in its evil ploy, both stopping the program and electrocuting himself, prompting the real Batman (who was hiding on a conveniently placed cliff crag) to wonder if his robot duplicate actually had a soul.
 * In Justice League Unlimited, when, Superman rounds up the founding members and questions: "What have we done?" Doubly subverted, though: First, they tell him that they haven't done anything, since someone else hijacked their main computer. However, he replies that it was their choice to keep the orbital cannon, therefore all of them must take the responsibility.
 * Appears to be this in the episode "A Dumb Wish" in The Grim Adventures of Billy and Mandy with Mandy when she accidentally wishes everyone on Earth away into oblivion ...but then she gives an devilish smirk and goes home to watch TV.
 * Zummi says this in the Grand Finale of Gummi Bears, after his carelessness results in Duke Igthorn capturing most of the Gummis, learning the secret of Gummiberry Juice, and taking over Dunwhyn Castle.
 * In Space Ghost Coast to Coast, one episode deals with a pledge drive that's not going very well. Frustrated, Space Ghost orders the audience to give him money, or he'll shoot Brak. Brak starts crying, and Space Ghost feels ashamed of what he's doing. Brak calms down and tells him that "it's okay", which Space Ghost cheerfully takes as permission to shoot him.
 * In another episode, Space Ghost takes revenge on Zorak for thrashing his apartment by blasting him so many times he ceases to exist (or so he thinks). When he realizes that he actually killed him, Space Ghost shouts "Heaven help me, what have I done?!" before casually following up with "Oh well" and continuing the show without him.
 * In the South Park episode "Something Wall-Mart This Way Comes," one of the creators of Wall-Mart exclaims, "Jesus, what did we do?!"
 * The mayor of South Park also utters this after surveying the Hippie Music Jam Fest that she signed the permit for in "Die, Hippie, Die."
 * The sellers of Ritalin use this exact phrase (well, in plural form) when they learn that by prescribing it to everyone, they now have a town full of children who like Phil Collins.
 * Edd says "Oh dear, what have I done?!" in "Pain in the Ed" after  It even sends him into a tear-filled Heroic BSOD.
 * And in The Movie while writing a farewell letter to his parents for the Eds scam Gone Horribly Wrong.
 * Possible villainous use in Avatar: The Last Airbender, when Ozai accidentally fixed Aang's chakra flow with an Improbability Drive rock. You know that as Aang was kicking his can all over the place, Ozai was just thinking "What the hell did I do?!"
 * Aang's got your beard!
 * Zuko had an extended one for the first half of the third season. His hasty actions at Ba Sing Se started to seem less heroic and more despicable, culminating in his goodbye speech to Ozai during the invasion.

"Phil: I thought Chuckie let go of the balloon.

 * On The Critic, Eleanore Sherman utters this when she finally sees firsthand the humiliating affect her book, The Fat Little Pig, has on Jay's life.
 * Rugrats plays with this. Chucky says this when he's told to release a balloon holding Angelica's doll. Suzie said it was Angelica who released it as punishment. Phil and Lil, well...
 * Rugrats plays with this. Chucky says this when he's told to release a balloon holding Angelica's doll. Suzie said it was Angelica who released it as punishment. Phil and Lil, well...

Lil: No, Angelica let go of the balloon. You just weren't paying attention.

Phil: Oh."

 * Spongebob SquarePants: In "Band Geeks", after everybody that Squidward gathered for 4 nights of band practice, and on the final night, fought over differences and hurt Squidward's feelings:

 * In the My Little Pony Friendship Is Magic episode "Lesson Zero", Twilight Sparkle has this reaction after her insane attempt to create a friendship problem via an Apple of Discord goes horribly, horribly, right.
 * In "Sisterhooves Social", Rarity totally loses it with her sister after an entire day of getting on one another's nerves (including when Sweetiebelle makes a picture out of the rare gems Rarity had been saving for a dress for an important client), resulting in a huge argument which makes both swear that they wished they were only children and storming off. Later on she's tidying up and looks at the picture again, Rarity’s reaction is almost word for word.
 * "Secret of My Excess": Spike doesn't come right out and say it, but the emotion is conveyed by his reaction to seeing Ponyville devastated, and his own giant footprints.
 * Happens in Hearth's Warming Eve when Clover the Clever (Twilight), Smart Cookie (Applejack), and Privite Pansy(Fluttershy) discover that the blizzard that destroyed their homeland and is now threatening Equestria is caused by Windigos, winter spirits that have been feeding off of the hatred between the three tribes of ponies, meaning their pointless hatred for one another was the cause of everything that has happened.
 * In Baby Cakes, despite being only a month old, the Cake Twins are smart enough to realize they've gone too far when they realize they've made Pinkie cry.
 * The entire town of Ponyville gets one in The Super Speedy Cider Squeezy 6000, when their support of the Flim Flam brothers almost causes the Apple family to lose their entire livelihood.
 * Fluttershy gets one in Putting Your Hoof Down after being a huge bitch to Pinkie Pie and Rarity, due to taking her assertiveness lessons from Iron Will.
 * Twilight has one in A Canterlot Wedding when everyone calls her out on calling Cadence evil.

The first time is when he realizes that instead of calling a temp agency, he's called the Warners and told them he needs help in the office while his secretary is out sick. The second time is when he ''agrees' to the Warners helping him out. Needless to say, his fears do not go unwarranted.
 * In an episode of the Krazy Kat animated series, Krazy is Born Lucky, and Ignatz is jealous and wants her luck for himself. Then he comes up with the perfect solution--he'll give her some Cement Shoes, get her to sign her luck away to him, then dump her underwater. Only after he's already done this does he have this reaction and dive underwater to save her.

""I almost killed my own daughter. I'm a monster!""
 * In the He Man and The Masters of The Universe episode "The Problem With Power", Skeletor tricks He-Man into believing he's killed an innocent bystander (really a minion who was Faking the Dead) with his carelessness. In the Heroic BSOD that follows, He-Man retires. Fortunately, Orko finds out about the trick, and tells He-Man.
 * During a Halloween episode of Hey Arnold, the kids go trick-or-treating disguised as aliens. Unfortunately, a War of the Worlds-style radio broadcast convinces the adults that it's an actual alien invasion, who then form a lynch mob out to get the kids. (It doesn't help that they accidentally used exterior latex paint instead of facepaint, which doesn't rub off.) At the climax, Bob Pataki grabs Helga by the neck and starts choking her, only to realize his mistake when it starts raining and the paint finally washes away.


 * Arnold felt this when he.
 * Madagascar. Kind of a "My God, What Did I Almost Do?" moment with Alex

Real Life
"I remembered the line from the Hindu scripture, the Bhagavad-Gita. Vishnu is trying to persuade the Prince that he should do his duty and to impress him takes on his multi-armed form and says, "Now I am become Death, the destroyer of worlds." I suppose we all thought that, one way or another."
 * The page image is of Tsar Ivan IV the Terrible holding the body of his son, the Tsarevich (heir apparent) Ivan. The Tsar decided that his son's his pregnant wife was too immoderately dressed (or something), and the younger Ivan jumped in to defend her; in a fit of rage, the Tsar proceeded to beat down on his son with his scepter. Heavily. But when Tsar Ivan realized that his son was almost dead, he started kissing him and trying to stop the bleeding, crying, "May I be damned! I've killed my son! I've killed my son!". His son regained consciousness long enough to deliver some Tear Jerker last words, and then remained comatose until dying a few days later--during which his father remained awake for long hours praying constantly for a miracle.
 * Captain Robert Lewis, co-pilot of the Enola Gay, watched the city of Hiroshima disappear in an atomic blast. Some members of the crew would claim that Lewis was at first caught up in the moment and yelled, "My God, would you look at that sonofabitch go!", but after he calmed down, Lewis wrote in his log, "My God, what have we done?" (The rest of the crew maintained that they did what they had to do).
 * As he watched the first atomic test ever at the Trinity site:

- J. Robert Oppenheimer, Scientific Director, Manhattan Project

"Now we are all sons of bitches."
 * Likewise:

- Kenneth Bainbridge, Trinity Test Director, Manhattan Project


 * On the topic of WW 2, the Marines having arrived on Okinawa, experienced no resistance from the Japanese. This had the marines extremely on edge, especially the first night since the Japanese were infamous for night attacks (especially of the Banzai Charge nature). Unfortunately that night, a convoy of Okinawan civilians were fleeing the Japanese. The Marines thinking it was a Banzai Charge... This trope was the reaction of the Marines.
 * Ashoka the Great, emperor of India in the 3rd century BC, is said to have uttered this line after a bloody military campaign and then converted to Buddhism and never waged war again. That's right, Older Than Feudalism.
 * Alfred Nobel developed dynamite in order to make the nitroglycerin used for mining, quarrying and construction safer to use. Instead it became widely employed as a weapon, to the point that a paper mistakenly published his obituary on the occasion of his brother Ludvig's death, with the title "The merchant of death is dead". His personal fortune at the time of his death was approximately 250 million dollars in today's money. He bequeathed 0.5% to his family, and the rest to the newly founded Nobel foundation. He also specified that race and nationality was not to be a factor in choosing recipients, which caused a major stir at the time. (The prize committee made good on this specification relatively quickly, giving the Literature Prize to Indian Rabindranath Tagore in 1914.)
 * Sociologist Robert Putnam was so horrified by the results of a study he performed that among other things suggested that racially diverse societies caused individuals to become more isolated that he almost didn't publish it. He did eventually. When criticized about witholding his findings he explained that he was terrified his work would be used by racist organizations to justify their hatred.
 * When the hysteria died down following the Salem witch trials, the people of Salem went straight to Psalm 51.
 * A classic sports example of this happened when Lawrence Taylor gruesomely (but inadvertently) broke Joe Theismann's leg. As soon as it happened, Taylor -- known then as a vicious defensive player and a bit of a trash-talker -- immediately and frantically called to the sidelines for the medical staff to come and help Theismann, knowing that he'd inflicted an exceptionally serious injury. Indeed, it ended Theismann's career.
 * A rather literal example is HMS Beagle captain Robert FitzRoy, who was a fundamentalist Christian creationist. He regretted being part of the Beagle expedition that led to Darwin publishing On The Origin Of Species, thereby indirectly contributing to the development of the theory of evolution, which contradicted The Bible's account of creation( though now it's thought to be one valid interpritation by some, including the Vatican). It may have contributed to the depression and anxiety later in life that ultimately led to him committing suicide.
 * A common reaction by people when they kill someone, especially the first time. The degree of trauma depends on a number of factors, such as group participation (squads, teams, etc), range (greater distance = more detachment), emotions and weapons used.
 * It's a YMMV reaction more than anything else; it is impossible to know how someone will react to killing beforehand. Some people BSOD, others find the experience intoxicating. Most people just feel a bit uncomfortable about it for a while but remain psychologically healthy.
 * Stephen King had one of these after he found out about the number of school shootings that had been linked to his novel Rage, in which a high school student snaps after being expelled from school, takes out a pistol, and then kills multiple people as well as hold several students hostage and is portrayed as a Sympathetic Murderer. Investigation of students who had started shootings in their schools revealed that several of them had copies of Rage in their possession. Stephen King then requested that Rage be taken out of print in an attempt to make up for it.
 * The story goes that General Launcelot Kiggell, Chief of General Staff in the British Army in World War One, saw the conditions at Passchendaele at the end of the battle, cried "My God, did we really send men to fight in that?" and burst into tears. Now considered to be anecdotal, as the higher-ups knew damn well what the conditions were but had legitimate military reasons for continuing. (Whether those reasons constituted justification for continuing is a matter for debate.)
 * First car crash anyone?
 * Even more so if you just happen to run over someone's pet, more often than that, you will feel like a Complete Monster. Unless, of course you just don't care.
 * Many raiders who run in on people in their homes threatening the occupants and getting them to tell said raiders, for example, the password to the home safe, will hate having to do this to parents of kids (particularly if the kids are seeing the whole ordeal). There have even been cases in which robbers have turned themselves in due to their guilty conscience about how they tramutized a poor kid haunting them. Some raiders will even try and comfort the kids, if they have to.
 * A Real Life self-styled Evil Debt Collector quit the industry after he discovered that a woman he'd tried to collect from died in 9/11.
 * Oft experienced after a binge drinking session, especially with some of the more foul tasting beverages.
