Times where someone Kicks the Morality Pet in Anime and Manga.
- In the manga adaptations of Angels of Death, Catherine Ward is shown in her high school Alpha Bitch days to have had a Beta Bitch, Lucy, devoted to her and helping her carry out her bullying and murders. As adults, the two ran a prison where they sadistically tortured the prisoners. Cathy grew to genuinely love Lucy, who reciprocated the feeling. Which is why Cathy tied up Lucy and chainsawed her to death- she wanted her first kill to be someone special to her. Worse, Lucy has been so broken by Cathy that she is happy to be killed by her beloved.
- Attack on Titan:
- Reiner uses the massive strength of his Titan form to begin hurling Titans at the escaping soldiers and nearly kills several of his former friends in the process. It's used to illustrate just how far over the Despair Event Horizon he's gone and reaffirming his claims that I've Come Too Far. Armin even responds in shock, wondering aloud whether he even cares anymore about the danger of Eren being devoured by Titans. Hange later theorizes that killing Eren was his actual goal in doing this, having given up on simply kidnapping him.
- Much later on, Eren himself shows how far he's fallen by acting cruelly toward his closest friends. He gives Mikasa (who's always been in love with him) a "The Reason You Suck" Speech claiming he's always hated her, then beats up Armin when Armin punches him in retaliation.
- Black Clover: Licht shows care for his subordinates when he's furious at Asta for harming Valtos. He later reveals that it was a ruse, revealing that he always hated his human underlings before he sacrifices them all to complete the elves' reincarnation.
- Dragon Ball Super: Beerus meeting Goku is the reason why he goes from an amoral, selfish God of Destruction who will destroy anything that annoys him, to being the overall Big Good in Super. However, Beerus has no problem reminding Goku that he is a god while he is just a mortal whose power can't compete with him or any God of Destruction. The most vicious kick he gives is when he mocks Goku for trying to stop Champa from killing his own team, saying that since Champa is a god, he can do what he wants in his universe, and there is nothing Goku can do to stop it. He also seems to agree with Champa that Goku and the others are pawns to the gods.
- Durarara!!: Everyone assumes that Izaya did this to Shinra in middle school for no reason whatsoever. Turns out, he told Shinra to tell everyone that he stabbed him so he can use this opportunity to ruin Nakura who even dare hurt his Only Friend. Naturally, it's implied that Izaya also did this so no one will find that how close he is with Shinra.
- Elfen Lied: Lucy brutally kills Kouta's sister Kanae in the middle of what's basically a mix of a psychotic breakdown and a hissy-fit of jealousy. While she's still murderous after that due to other unrelated events, quite a bit of guilt over said incident remains in her heart.
- The Familiar of Zero: Happens to Agnes (at least in the novels), when Saito, Louise and everyone is fleeing the country to save Tabatha who is about to meet a Fate Worse than Death at the hands of her uncle, the King of Galia. Anies had orders to only arrest the group and no intention of harming them, but as soon as she sees her lifelong nemesis Colbert responsible for her Doomed Hometown, whom she thought was dead, she snaps and opens fire. The shock from the realization she nearly killed Saito in the process, whom she trained and considered as a friend, has her realize that even if she killed her nemesis, other people would hate her in turn, so hatred and revenge are meaningless and that someone has to take it on himself to end the hatred here and now. She didn't forgive him, but is at least able, now, to look at his face without feeling murderous urges, or at least without acting on them.
- Fullmetal Alchemist:

While the series implies a Heel–Face Door-Slam for Michael and his lover Fasalina, who likewise snapped out of her loyalty to the Claw both appear to be crushed under rocks and averting Just A Fleshwound, Wendy's shot is implied to be fatal, supplemental materials go for Redemption Earns Life.

- Mobile Suit Gundam SEED Destiny: Shinn Asuka comes extremely close to doing this in the final battle when he is fighting against Athrun Zala and the Infinite Justice Gundam. Already descending into a Villainous Breakdown due to Athrun calling him out for his irrational hatred towards Orb, Shinn completely loses it when his girlfriend, Lunamaria Hawke, has a Heel Realization and jumps in-between him and Athrun, trying to get them both to stop fighting. But Shinn is so far gone at that point that he charges anyways, fully willing to tear through Luna and her Impulse Gundam if it means he can reach Athrun. Thankfully, before Shinn can kill her, Athrun snaps into SEED Mode, shields Luna from Shinn's attack, and then proceeds to swiftly end the fight by demolishing Shinn's Destiny Gundam, sending it crashing into the moon. Shinn survives, but then lapses into tears, very much regretting what he nearly did.

- Sands of Destruction: In the manga, Morte finished her job in a city where the beastmen were eating humans. After berating Kyrie of doing something reckless, she blows up the entire city that they just saved for the fun of it. This action causes Kyrie to snap at her and he leaves the group which causes the group to split up (with Toppi and Naja going with him and Agan staying with Morte.) When he comes back, he throws the gun that she gave him to defend himself on the ground telling her that he doesn't need it anymore since he's not coming back. Cue, she snaps and attacks him proving Kyrie's point why he can't stay with her. Thankfully Toppi and Naja stopped her attack.
- Sailor Moon: During the "Sailor Galaxia" arc, Sailors Uranus and Neptune come up with a ruthless plan to defeat the titular Big Bad by feigning loyalty to her in order to be given one of her Star Seed-extracting weapons, and then turning said weapons on her.

They don't even hesitate to kill them both... and then it turns out that Sailor Galaxia's weapons won't even work on her, because she doesn't have a Star Seed.

Kanaka pulls a laser gun to try to frighten Narue off, and after a brief tussle, Kanaka completely unintentionally shoots her. Fortunately it was a non-lethal gun to begin with, but it's still enough to get Kanaka to thoroughly regret her actions. Well, that and some manly tears from Kazu.
