No protagonist is perfect. Every man, woman, child, or person of ambiguous or nonstandard gender brings their own unique flaws and difficulties to their role in a story. Often stories will be about a protagonist's struggles to overcome these flaws. However, whether they succeed or fail, many of them will experience at least one Moment of Weakness. That instant in which their emotions or the stress of a situation goes past critical and causes a thoughtless reaction that they would never have if they were thinking clearly.
A Moment of Weakness can come and go, but will usually be recognized very quickly by the perpetrating protagonist. The typical response is usually one of two extremes. Either they'll wonder with horror "My God, What Have I Done?" and try to atone for it or it will be the first step in a running jump off the slippery slope. On occasion, you can even get someone who realizes the horror of their action, but not have that be enough to stop the leap.
To mitigate the potentially subjective nature of this trope: A Moment of Weakness is a single moment in which a character's emotions or stress levels run so high that they act contrary to their usual nature. This action almost always causes damage of some kind, most commonly to someone or something the protagonist truly cares about. This is one cause of O.O.C. Is Serious Business. Do not be surprised if an Oh, Crap! follows.
It is not necessarily something that the character will look back on as My Greatest Failure after the fact, but chances are that they definitely will be thinking of and agonizing over it as one of their more serious personal mistakes.
See My God, What Have I Done? for more long-term examples and Start of Darkness when the Moment of Weakness sends them the other way. If a rash action during such a moment leads to tragedy, see A Tragedy of Impulsiveness. Can potentially result in Insult Friendly Fire or Kick the Morality Pet. Compare In Vino Veritas, when this sort of thing can happen due to drunkenness, and Too Desperate to Be Picky, where they violate their own personal standards for the sake of a need. Contrast Sudden Principled Stand.
- Dragon Ball Z:
- Gohan considers the moment when he cowered behind a rock instead of attacking Nappa back in the Vegeta arc to be this. Moments afterward, Tien dies, and he blames himself for not being strong enough to prevent it. Worse, Piccolo agrees with him and chews him out even more, nearly dismissing him. Even in the Cell arc in the anime, it's shown that he still feels guilt over this, enough for it, and his other insecurities, to push him into a Super Saiyan transformation for the first time.
- Gohan has another when he lets his Super Saiyan 2-fueled bloodthirst get the better of him during his fight with Cell. Rather than finish Cell off, he decides to drag it out and torture the bioweapon. This leads to Cell getting desperate and self-destructing, forcing Goku to perform a Heroic Sacrifice.

- Code Geass: Lelouch boasted that if he had to abandon his conscience to exact revenge, he'd discard it — mere minutes before abandoning the people who were relying on him to go search for his little sister during the 1st Assault on the Tokyo Settlement (quite literally as soon as he started it).
- Saki's Hajime Kunihiro gave in to the urge to use sleight of hand to win a Mahjong tournament in grade school. Even into high school this act haunts her, undermining her confidence to play without doing so. This is the reason she's Chained by Fashion and wears handcuffs much of the time.
- Bitter Virgin:

- Same with his childhood friend Yuzu, she accidentally overhears Hinako's dark secret. At first she is willing to keep it to herself but after hearing that Daisuke has already confessed to her, she blurts it out. She feels utterly horrified at herself when she discovers that not only is Hinako right behind her, but that Daisuke already knew.
- Ling in Fullmetal Alchemist knowingly makes a Deal with the Devil and allows himself to become the new Greed because of his obsession with gaining immortality.

- My Hero Academia shows one for Rei Todoroki during a flashback in the Sports Festival. In it, she's talking to her mother over the phone about how her husband, Pro hero Endeavor, has been abusing her and her children, to a point that her son Shoto's left side only reminds her of his father. She openly states that she thinks she's losing it. The second an eavesdropping Shoto makes himself known, we only see the all-consuming terror and hatred in her eyes before she empties a boiling kettle of water on Shoto's face.

As Raphael repeatedly chips away at Yugi's lifepoints and backs him into a corner. Yami, against Yugi's protests, play the Orichalcos card, desperate to avoid defeat despite there being no risk in losing as long as the Orichalcos card isn't played. While it gives him an advantage, he constantly sacrifices his monsters to do so. This leads to falling right into Raphael's tactics and losing both the duel and Yugi's soul who went in his place as the seal only needed one of them. Needless to say Yami has a Heroic BSoD for awhile after that.

Sukeroku gets riled up to the point of nearly attacking his master, which gets him expelled.

When Tony is able to evade capture and clear his name, he forgives Pepper for her betrayal. Pepper breaks down and cries as Tony hugs her, saying "You don't have to say that. You have every right to think I let you down because I did. Stretch got me worried about Happy and I should have been stronger, or cleverer" as Tony says everything is OK.

The same panel shows a hysterical Blinky being the one to propose the idea.
- In his book Writing for Comics and Graphic Novels Peter David discusses how hard it is to pull off this trope in long-running comics. He explains most people would have no problem believing a real-life upstanding, law-abiding person had, after accidentally running over somebody, panic and flee from the scene of the crime. But people are so attached to their favorite fictional characters they would strongly oppose a story saying someone like Mary Jane Watson could do it.
- In Mega Man: Defender of the Human Race, Mega has one in episode 8 when he presses Wily's Berserk Button while trying to negotiate with him and Drill Man; he regrets it almost immediately.

Ebby continually pleads to reconcile, even going so far as to bring in Foal Protective Services. When Scootaloo runs away, Ebby pursues her and winds up hanging from a cliff. Scootaloo, absolutely desperate to have her mother out of her life forever, flat-out refuses to try and help her, leaving her to her fate. Scootaloo soon realizes she went too far and her mother (who was rescued anyway) realizes just how much she's hurt her daughter. This leads to a slow but genuine reconciliation.
- A couple of sidestories of Pokémon Reset Bloodlines have examples of this:
- In the Butterfree Interlude, Ash's Butterfree becomes upset when the group reaches the spot where his species find mates, after having heard the mating Butterfree were caught by criminals. When Ash tries to talk to him, he angrily lashes out, thinking that Ash just dragged him back to his adventure without a care, and leaves in a huff to try and find his mate from the previous timeline. He does find her, but it turns out she's in a relationship with another Butterfree, and she seems happier than she was with him, so he ultimately lets her be.

- In the Hala & Hau Interlude, the former is getting depressed due to how the current generation is losing interest in the trials, as well as Kukui's proposal of creating an Alolan Pokémon League. When he asks Hau if he thinks the trials are getting old-fashioned, Hau says no, despite how appealing a Pokémon League could be. Hala remarks that he never said anything about a League, and thinking that Hau is losing interest in the trials as well, he lashes out on him, even telling him to leave just like his father did years ago over similar disagreements. This scares Hau so much that he almost follows through with it.

Kiara is furious with him, saying that Mufasa wouldn't want that and that he'll never be like him, causing Simba to reconsider his actions.
- In My Little Pony: The Movie (2017), Twilight Sparkle, the "Princess of Friendship", faces her friends antics being unhelpful or liabilities in their quest to save Equestria and decides friendship won't work this time.

- Spoofed in Water (1985).
Reverend: Am I never to be forgiven for one moment of weakness?
Baxter: According to our latest census you've had at least fourteen moments of weakness, Eric.
- Carrie: Implied. According to Rita Desjardin, Sue Snell is not a bully by nature and therefore joining her classmates in gleefully taunting Carrie and pelting her with tampons was very out of character. It is implied that Sue only acted under peer pressure, being one of Chris Hargensen's cronies. Sue was actually disgusted with herself; she unfriended Chris, and tried to make up with Carrie by having her boyfriend take her to prom.
- In The Dresden Files book White Night Harry is forced to acknowledge the steadily growing influence of Lash after he loses his cool and destroys part of a building with his magic.

- In Memory, Miles covers up an assignment that was horribly botched because of health problems which he had also been keeping from his superiors. Although he's always breaking rules, up to this point it had been for the greater good; this time it was mostly selfish and he is dismissed from imperial service as a result. Later in the novel, when considering the villain, Miles notes that this could have been the point at which he did a FaceHeel Turn, but unlike the villain, he stopped himself.
- In Harry Potter and the Deathly Hallows, it's revealed that it was exactly such a mistake that caused Severus Snape to forever destroy his friendship with the one person he cared for when he called Lilly Potter (then Evans) a mudblood. A mistake like this also sealed Dumbledore's fate when he realized he had the Resurrection Stone in his hands. He immediately put it on hoping to summon his dead family and tell them how sorry he was about his sister's death, forgetting that it was also Voldemort's Horcrux meaning it likely had a powerful curse on it. This curse ensured that Dumbledore would die after about a year or so even after Snape helped him limit it to his hand.

As she's wondering, he embraces her and, on the verge of tears, asks her if they can just forfeit the Grail War, rescue Ilya, and live together in peace.
- In the first Safehold book, Off Armageddon Reef, Merlin acts entirely without thinking when a group of children are attacked by the Safehold equivalent of a shark; in the process revealing a portion of his more-than-human abilities to someone whose trust he needs and could easily view his abilities as demonic. Merlin only realizes this a few seconds after he's already committed to action. Only the fact it was a blatant act of Chronic Hero Syndrome that Merlin never considered not doing allows him to retain the trust he's earned.
- Journey to Chaos: Tasio has been waiting for Eric to have a particularly bad day, because only then would he ask for help. The Trickster needs him to do this so he can deliver the Call to Adventure and drop him in another world.
- In The Sea and Little Fishes, Nanny Ogg has a moment where she reflexively thinks that Granny Weatherwax could have hurt a child. The thought makes her deeply ashamed for the rest of the story and underlines just how successful Granny's Paranoia Gambit was.
- The short-lived television series G Vs E generally had villains who convinced people to make a Deal with the Devil, and good guys getting them to break those deals at the cost of what they were given. One episode stands out, however, as the bad guy of the episode approached people on the verge of death from accidents and used these deals to save their lives.
- Babylon 5:
- Lennier at the end. In his case he pays penance for the rest of his life, apparently dying in the Telepath War.
- Delenn at the Earth-Minbari war. Like Lennier, she too pays penance for her tragic mistake.
- Sheridan while interrogating Mr Morden. Unlike the two previous, he's stopped before his actions result in greater tragedy.
- Kamen Rider Build: Shocked and unable to come to terms with the fact of his father allying with Evolt, Sento attacks Ryuga before he could injure him any further, putting him in a coma, which also leads to him losing Kazumi and Gentoku's trust in him.
- In Dawn of a New Age: Oldport Blues, the stress of gaining telepathy along with pre-existing mental issues causes Zia to snap and nearly use her power to choke Ivy and Jessica to death. A flashforward shows her choking out Ivy again after she dares to mention Finn's name, who's implied to have turned against the heroes. Both times she snaps out of it and is horrified at what she's done.
- Even Commander Shepard from the Mass Effect series isn't immune to this, though his/her single (so far) Moment of Weakness potentially happens in a very sheltered environment and doesn't have any lasting consequences: in the end of the Lair of the Shadow Broker storyline, Liara comes to visit Shepard and asks him/her how s/he is truly feeling rather than what s/he tells the crew. The Paragon answer to that is the first and only occasion the Commander expresses any doubt about his/her mission in the entire series (depending on whether this takes place before or after the Suicide Mission, Shepard will refer to the latter or to the impending Reaper invasion). Also, this speaks volumes about Shepard and Liara's relationship (regardless of whether romance was pursued).
- S/he also shows it if you pick the renegade options (not really renegade but just different emotional responses) where Shepard both talks about just how hopeless his/her war against the Reapers seems and how exhausted s/he is from dealing with Cerberus, the Citadel Council who always treat him/her like s/he's lying or insane, and of his/her closest friends shunning him/her because s/he's working with Cerberus.
- S/he has a ton of them in Mass Effect 3 where s/he finally starts to crumble, physically and mentally, under the pressure of being the spearhead of a war effort against a nearly unstoppable enemy force. All of his/her friends constantly worry about him/her and do what they can to keep her from going completely past the Despair Event Horizon. S/he very nearly has a Heroic BSoD after the Fall of Thessia.
- One particularly notable one is during the assault on the Cerberus HQ, when Shepard finds a video describing how bad his/her body's condition was following his/her death at the beginning of 2. Almost completely absentmindedly, without even thinking about what they're in the middle of or the people around him/her, s/he goes into a brief existential crisis over whether or not s/he's the real Shepard or just an advanced VI programmed to think it's Shepard, talking more to him/herself than anyone else. It takes his/her True Companions and possible Love Interest reassuring him/her that they believe s/he is real to snap him/her out of it.
- In Dragon Age II, any companion you bring into the Fade in the sidequest 'Night Terrors', no matter how high their friendship or rivalry score is, will fall for the demon's offer and attack you (except for Anders, who's immune due to Justice, and Sebastian, who refuses to go in the first place).
- Katawa Shoujo: Go on. You know you want Misha, don't you? She's right there. All you need to do is say "yes"...
- Sonic has a particularly nasty one in Sonic Boom: Rise of Lyric. After warding a wave of robots outside of Lyric's Tomb, an even larger wave shows up. Whereas Knuckles, Amy and Tails move into place to face them, Sonic just sits there paralyzed; in his panic, he moves to open the door, with Amy telling him not to. Then Metal Sonic shows up, and Sonic caves, opening the tomb and leading everyone inside. Not only does this lead to Lyric getting loose, but Sonic gets on the bad side of everyone watching: Amy, Knuckles, Tails, and even Shadow, who saw the whole thing from above.
Tails: Uh... I don't think those doors were built to keep us out... they were meant to keep that in!
Amy: Let's get out of here! Oh, wait I forgot. We can't.
Knuckles: Not cool, Sonic! You locked us in!
Sonic: Locked us in? I was saving you!
Knuckles: We didn't need saving!
Amy & Tails: Yeah!
Shadow: Saving the world? You? Don't make me laugh. You're weak! And you know what makes you weak? Your loyalty to your pathetic friends! You're not going through that portal... I'm going to show you just how weak you are!
- In her background, as related in Touhou Bougetsushou, Touhou's Fujiwara no Mokou followed a troupe of soldiers to the top of Mount Fuji when they were about to dispose of an Immortality Inducer elixir.

When he was about to dump the thing into the volcano, he received a divine message telling him not to, lest he trigger a permanent eruption. Mokou took advantage of the tired soldier and killed him, taking the elixir for herself. Centuries later, she still feels enormous guilt over killing Iwakasa.
- In Telepath Tactics, Emma does not take her reunion with Silithis Predat well. In a departure from her normally reserved behavior, she immediately assumes the worst of Silithis and insults her when Silithis tries to apologize for her past abuse.

- In Undertale's backstory, the monsters' king, Asgore, declared war on humanity after a group of violent humans directly caused the death of his son within a day of the death of his and his wife's adopted human child. Asgore made the decision in grief and anger, but by the time he realized what he had done his declaration had given the monsters hope of eventual freedom from the Underground in which they were sealed. This left him feeling unable go back on his decision. He tried to Take a Third Option by just taking the souls of humans who fell into the Underground. However that accomplished nothing except causing the monsters suffer more because Asgore did not want to dirty his hands. This act so disgusted his wife she left him soon after.
- Tiamat in Final Fantasy XIV admits to this when she tells her story to the Warrior of Light. Her brother, Bahamut, was killed by the Allagan Empire 5000 years prior. Filled with grief and rage, she consorted with the Ascians and learned how to bring her brother back to life. Said brother came back as a bloodthirsty primal that rampaged across the land and was captured by the Allagans. Realizing the horror she unleashed, Tiamat, who was shackled in place by the Allagans, atones for her actions by keeping herself bound as punishment.
- In the God of War series, Kratos, as a Spartan, is usually as fearless as he is tough. But there was that one time he pledged himself to Ares, the War God, because he feared dying to a barbarian horde. Kratos' life was saved. Then, Ares tricked him into killing his own family. It only got worse for him from there.
- Persona 5 has Makoto Niijima, the Student Council President of Shujin Academy. She is under constant pressure from the school and her older sister to succeed in life. Things come to a head after Principal Kobayakawa relegates to her the task of determining the identities of the Phantom Thieves. She takes this opportunity to blackmail the Thieves into stealing the heart of a crime boss in Shibuya, lest she release evidence to both Shujin and the police. After an outburst from Sae, and offhand comments from Goro Akechi and later Ann Takamaki, Makoto tries to prove that she isn't useless to anyone by getting the Thieves into contact with the crime boss—which gets all of them into Kaneshiro's attention. Though things turn out positively in the long run, Makoto acknowledges that her desperation has put her schoolmates into danger, and pleads with the Thieves to let her handle this so as not to further embroil them.
- The Order of the Stick, Varsuuvius made the decision to make a Deal with the Devil (and Demon, and Daemon). V knew that dealing with infernals was a bad idea, and they even offered an alternate method where the elf would owe them nothing. However, at that point, V was trance-deprived, guilt ridden, and both pride and body were crushed by a dragon, who was minutes away from killing the elf's family. Varsuuvius, unable to admit defeat like the alternate method would require, makes the deal and takes a step towards The Dark Side. The strip is even titled "The Wrong Reasons" in reference to a prophecy that Varsuuvius would obtain ultimate power by saying the right four words at the right time for all the wrong reasons.

- Schlock Mercenary: Played for Laughs. While Admiral Chu was auditing all the terrible black-ops projects in his military to drag them into the light, his people found a really big gun. Chu admits that, in a moment of weakness, he code-named it "Zeus" and let them test fire it. The shot could be seen from the other side of the solar system. His superior dryly points out that this isn't going to make the civilians feel better about all those military black-ops projects.

- Zuko subverts pulling a HeelFace Turn despite having every reason to do so, which disgusts his uncle Iroh. Later, when Ozai revealed his plan to burn the Earth Kingdom to ashes, Zuko didn't protest it (because he remembered what happened the last time he did). That made Zuko realize that he had lost his courage, and that was the final push he needed to join Aang's side, double-subverting the HeelFace Turn.
- The Legend of Korra:
- Korra has a breakdown at the end of "The Voice In The Night". She makes a public challenge to fight Amon at an appointed time and place, and naively believes he'll play fair. Amon does eventually show up for the fight, except he brings a dozen armed henchmen with him. They ambush Korra, tie her up, and drag her off into the darkness where Amon makes it clear to her that the only reason he doesn't kill her or take her bending is because that would turn her into a martyr, and he's too smart for that. After they take their leave, Korra is left sobbing into her mentor Tenzin's chest.

- In "Out of the Past", Talia offers Bruce an opportunity to restore his youth using the Lazarus Pit. He resists the temptation, but changes his mind after he and an innocent bystander are nearly killed in a mugging he once could have handled easily. It was a setup designed to trigger just that reaction.
- CatDog: In the episode "All You Need is Lube", a tick attaches to Lube's toe. Cliff and Shriek are too afraid of the tick to help Lube and run away, while Cat takes the tick off, so Lube decides to serve Cat for saving his life. When Cliff and Shriek come back, lying that they left to get help, Lube is not fooled and angrily calls them out for abandoning him and tells them he's with Cat now. Cliff and Shriek genuinely feel bad about letting Lube down and do try to make it up to him to earn back their friendship.

- In "For Whom the Sweetie Belle Toils," Sweetie Belle hits her Rage Breaking Point when she thinks Rarity deliberately upstaged her with costumes so good that the audience of the play she wrote, directed, and starred in found them more memorable than the play itself. In retaliation, she sabotages a headdress made for one of Rarity's most important clients. The episode focuses in getting her to realize her error and fix it before it's too late.
- In the Steven Universe episode "Rose's Scabbard", the discovery that Steven's mother Rose Quartz had secrets she kept even from Pearl, who thought herself Rose's closest confidante, sends her into a freak-out.

After a tense moment, Pearl flees the house, forcing Steven to go after her.
- Teenage Mutant Ninja Turtles (2012): In "Turtle Temper," Splinter states that one such moment on his part is partially what triggered Shredder's Start of Darkness, which he informs Raph of in an attempt to Tame His Anger. Splinter recounts an incident where Shredder openly and relentlessly insulted him in front of Tang Shen, eventually leading Splinter to lose his temper and attack him. This caused their rivalry to intensify, eventually leading to Shen's death at Shredder's hands. Raph claims that he had no choice but to get angry since Shredder was insulting him, to which Splinter retorts that he did have a choice: he could have just ignored Shredder's taunts and walked away, but he didn't.
Splinter: I could have chosen to ignore him. I could have chosen to let his words wash over me, like a river over stone. But I let him anger me. It was I who made his words into weapons. That was the choice I made. What choice will you make?
