History MoralEventHorizon / PuellaMagiMadokaMagica

** In [[Recap/PuellaMagiMadokaMagicaEpisode09IdNeverAllowThatToHappen episode 9]], which [[spoiler:takes place in the main timeline (known as Timeline 5 by the Puella Magi Wiki)]], it is revealed that he is responsible for the conflict because [[WellIntentionedExtremist they need an effective system to prolong the universe' lifespan]]. However, he proves to have [[JerkWithAHeartOfJerk no remorse about using morally reprehensible methods]] to enforce said system, particularly by tricking [[spoiler:Kyoko]] into believing that [[spoiler:Sayaka could be saved after turning into a witch, thereby leading to her HeroicSacrifice]] and leaving Homura as the only magical girl to fight Walpurgisnacht - all in hopes that [[spoiler:Madoka would contract with him]].

** If his counterpart in the Magia Record universe didn't cross it by [[spoiler:inciting a [[LetsYouAndHimFight turf war amongst the magical girls]] during Arc 2]], then he cements himself as the worst among his own versions by boldly [[spoiler:activating the Neo-Magius' MindRape device that causes everyone to witch out despite their leader Himena's reservations]].

** The franchise's witches tend to have [[BlueAndOrangeMorality bizarre]] and [[WellIntentionedExtremist even benevolent]] motivations, and [[spoiler:are even forced to MercyKill humans to spare them from the FateWorseThanDeath of being enslaved to the Incubators]]. And then there's [[spoiler:Isabeau de Bavière, a Witch-Incubator hybrid whose purpose is to annihilate France, an entire country, and actually came into existence thanks to the {{greed}}y desire of her magical girl - a.k.a. "[[RedBaron The Woman Who Sold Her Country]]" - to invade France. These facts make her the only known witch capable of crossing the MEH]], and she does so by [[PlayingWithFire incinerating]] [[ManOnFire several spectators]] at Charles VII's coronation.

** The [[AdaptationalVillainy anime version]] of Alina Gray crosses it when she [[spoiler:[[TheStarscream backstabs Touka and Nemu]] and fuses with Embryo Eve so as to obtain Walpurgisnacht's power, with the unambiguous intent to KillAllHumans by turning them into magical girls, knowing they would be [[LockedOutOfTheLoop completely unaware that Grief Seeds are needed to purify their Soul Gems]], effectively condemning them to witchification]]. And her reason for her plan: [[spoiler:to put on a show [[ItsAllAboutMe she wants to be remembered for]]]]. Since it's already clear-cut from the franchise's mythos that [[spoiler:witches are [[AndIMustScream well-aware of their suffering]]]], her plan and motive make her much worse than [[GenericDoomsdayVillain Walpurgisnacht]] and [[DarkMessiah Kriemhild Gretchen]] (who want to eliminate suffering for [[WellIntentionedExtremist their own twisted reasons]]), as does the fact that she is far more happy to [[spoiler:throw away her humanity than any magical girl on the brink of witching out]].

MoralEventHorizon in the ''Franchise/PuellaMagiMadokaMagica'' franchise.

* The fandom is divided on Kyubey, the franchise's WeaselMascot, but [[spoiler:some of his timeline incarnations have their own MoralEventHorizon crossings]]:
** [[spoiler:The Timeline 5 (main timeline)]] Kyubey [[spoiler:misled Kyoko into believing that Sayaka could be saved after turning into a witch, thereby leading to her HeroicSacrifice and leaving Homura as the only magical girl to fight Walpurgisnacht - all in hopes that Madoka would contract with him]],
** [[spoiler:When the Timeline 4 Madoka becomes a witch powerful enough to destroy the Earth, the Timeline 4 Kyubey doesn't care as [[YouHaveOutLivedYourUsefulness he got enough energy from humanity]] to halt entropy]].

* [[spoiler:Kyoko's father killing his entire family after finding out that his older daughter's wish was the only reason for his popularity, and then killing himself too. Kyoko survived but ended up bitter and amoral]].

* ''Manga/PuellaMagiSuzuneMagica'': If her previous actions weren't already enough, then [[spoiler:Kagari]] admitting that she made her revenge on [[spoiler:Suzune]] so convoluted was because it would be more ''fun'' for herself is what does it.

** [[spoiler:Kyoko's father]] is not the franchise's only AbusiveParent to cross the line. [[spoiler:"Nagisa's Wish", Nagisa Momoe]]'s backstory event, reveals that [[spoiler:Nagisa]]'s mother crossed it by demanding that her daughter use her one wish required to become a magical girl to murder everyone for the former's sake for no apparent reason (even if they're done nothing to her) instead of curing her illness. Given that this caused her daughter to instead make a spiteful wish and to some extent [[spoiler:led her to [[TragicMonster witch out]] and kill Mami in the [[Recap/PuellaMagiMadokaMagicaEpisode03ImNotAfraidOfAnythingAnymore original series' third episode]]]], she definitely deserved to [[GuttedLikeAFish have her organs stolen]] in the end of the story.

** Minou crosses it by [[spoiler: [[KinslayingIsASpecialKindOfEvil murdering her own sister Corbeau]] after the latter says that [[EvenEvilHasLovedOnes she loves her sisters]], even going as far to cover up her involvement in Corbeau's death from Lapin and frame Tart and friends for it]].
** The franchise's witches tend to have [[BlueAndOrangeMorality bizarre]] and [[WellIntentionedExtremist even benevolent]] motivations, and [[spoiler:are even forced to MercyKill humans to spare them from the FateWorseThanDeath of being enslaved to the Incubators]].

** If Yuuri didn't cross it in Chapter 3 with her attack on Kazumi, she definitely does so in Chapter 4 with the revelation that she [[spoiler:implanted Evil Nuts - fake Grief Seeds which create pseudo-witches bent on wreaking havoc - on innocent people.]]

** The suggestions from the end of the anime that Incubators and humans can somewhat coexist are completely annihilated by the end of the movie: [[spoiler:The Timeline 6 Kyubey's actions, which are actively malicious toward the girls rather than apathetic as they were in the show and cruel even by his standards combined with his willingness to screw over the Law of Cycles (which was giving him exactly what he wanted, just not quite as efficiently) and bring back the witch system drives it home that that he is ultimately humanity's enemy, and is fully willing to destroy the peaceful relationship the instant he benefits from doing so, simply for the sake of being able to acquire more energy more efficiently.]]
* [[spoiler:Homura crossed it for more than a couple of fans in her betrayal of Madoka and establishing herself as a devil figure, particularly the part where she erases everyone's memories. Counts in-universe, as Sayaka declares that [[ThisIsUnforgivable she'll always remember Homura as a demon for it.]]]]
