History MoralEventHorizon / FairyTail

* Anime/FairyTailTheMoviePhoenixPriestess: Duke Cream crossed it when he tries to have Éclair burned at the stake a sacrifice.

* If Acnologia didn't cross it by [[spoiler:brutally killing Igneel in front of Natsu, then he definitely crosses it by spitefully and sadistically destroying Irene's corpse for creating the Dragon Slayer Magic]]. Erza and Wendy's horrified reaction at the latter just highlights it.

* Duke Everlue crossed it when he forced a famous writer Kemu Zaleon to write a book about him by threatening to revoke his entire family's citizenship, and tossing him into prison cell for three years, all because he refused, culminating in Kemu being DrivenToSuicide.

* Jose Porla crosses it with his war on Fairy Tail by having Gajeel destroy Fairy Tail guildhall and beat up three of the guild's members, using Jude Heartfilia's request to bring Lucy back to him as an excuse to satisfy his jealously. He goes as far as to destroy all of Magnolia to do so and kill eveyrone in Fairy Tail to make Makarov suffer.

* Zancrow crosses it when he incinerates his own soldiers just for warning him about Natsu's strenght, only to go further into it when he reveals to Merudy that Ultear is the one who massacred her village.

-> '''Acnologia:''' As we stand inside here, my flesh form is on a path of rampant destruction outside the time rift. bringing about the end of the world. The hour of reckoning is now upon us. Civilizations reached it's demise.

** Duke Everlue crossed it when he forced a famous writer Kemu Zaleon to write a book about him by threatening to revoke his entire family's citizenship, and tossing him into prison cell for three years, all because he refused, culminating in Kemu being DrivenToSuicide.
** Erigor crosses it with his plan to kill all of the Fiore's Guild Masters as revenge against the magical world for his guild being declared a Dark Guild for refusing to reject assassination requests.
** Jose Porla crosses it with his war on Fairy Tail by having Gajeel destroy Fairy Tail guildhall and beat up three of the guild's members, using Jude Heartfilia's request to bring Lucy back to him as an excuse to satisfy his jealously. He goes as far as to destroy all of Magnolia to do so and kill eveyrone in Fairy Tail to make Makarov suffer.
** Similar to his master, Sol of Phantom Lord crosses it by [[MindRape mind-raping]] Elfman into reliving the night he [[spoiler:supposedly]] [[TraumaButton killed his younger sister]], before nearly turning him into stone and planning to have him [[FateWorseThanDeath experience the said memory for eternity]].
** Buli and Guli, a pair of Zeref cultists from the Tower of Heaven, crossed it in flashbacks, where they massacred several villages and [[WouldHurtAChild kidnapped their children to use them as a labor force]] necessary to complete the Tower, going as far to subject anyone who resists them to the ColdBloodedTorture.
** Brain crosses it when he shoots Cobra in the back for not defeating Natsu fast enough. However, he crossed the line before the events of the series, when he [[spoiler:subjected Ultear to torturous experiments and lied to her mother Ur that Ultear has died]].
** Zancrow crosses it when he incinerates his own soldiers just for warning him about Natsu's strenght, only to go further into it when he reveals to Merudy that Ultear is the one who massacred her village.
** [[BadBoss Ziemma Orland]] crosses it ''twice''. The first is when he kicks out Yukino for losing a match by having her strip herself naked in front of her guildmates and erase her guild mark. The second is when he [[spoiler:nearly]] [[KickTheDog vaporizes Lector]] [[EvilIsPetty for wearing the Sabertooth mark]]. The fact ''no one'' in Saber Tooth was seen smirking during those two acts highlights how much of a scumbag Ziemma is when compared to the rest of the guild.
** [[spoiler:Future Rouge crosses it when he kills Future Lucy in an attempt to kill her present self. This act ''instantly'' turns Natsu and company against him. He later tops himself when he reveals to Natsu that he killed Sting to absorb his powers.]]
** If Jackal didn't cross it by bombing the Magic Council building, [[spoiler: killing everyone but Dornabolt present]], then he definetely crosses it by nearly forcing Lucy into a SadisticChoice in either having an [[AssholeVictim elderly councilman]] or a '''pregnant woman''' be killed.
** Similar to Jackal, if Ezel didn't cross it by massacring an entire village just to get one council member, then he crosses it by nearly beating Wendy to death and trying to eat Carla alive in front of her.
** The EstablishingCharacterMoment for [[BadBoss Mard Geer Tartaros]] is also his MEH crossing. Torturing Kyoka for wasting her time by torturing a human is bad enough, but the fact he's perfectly fine with getting his own men absorbed by [[EldritchLocation Alegria]] is enough to tell the viewer he's just as bad, if not worse than Jackal or Ezel.
** Operation Purification, a plan of massacring a village full of innocent people to summon Zeref, isn't probably enough to qualify it as Arlock's MEH crossing, is it? It '''isn't'''. The moment he summones one of the Eighteen War Gods of the Yakuma, he immediately sacrifices his own followers and laughs like a maniac when they all begin to die. Any wonder why Zeref hates those who commit crimes in his name?
** [[JerkassGods Ankhselam]] has never been seen on-screen, but he quickly crosses it by [[spoiler:giving Zeref the worst curse imaginable - the one that makes person kill any living being if they expresses value for life - for trying to resurrect his younger brother, because it's something [[TheseAreThingsManWasNotMeantToKnow unmeant for mortals to mess with]]]]. For those who believe ''that's'' not enough, then we have him giving the same curse to [[spoiler:'''Mavis''', all because she used an incomplete Law spell to save a friend from a DemonicPossession by an ArtifactOfDoom]]. The fandom quickly agreed that he makes ''Acnologia'' huggable in comparsion.
** Invel Yura crosses it when he [[spoiler:forces Gray and Juvia to fight each other to the death, fully expecting Gray to win so that his inner darkness can awake and turn him into a warrior who can kill E.N.D. (i.e. Gray's [[VitriolicBestBuds friendly]] [[TheRival rival]] Natsu, meaning Gray would have killed two of his friends), an action that forces Juvia to perform a HeroicSuicide, since she doesn't want to kill Gray or have him live with the guilt of killing her]].
** In Irene's flashbacks, [[spoiler:General Rung crossed it when he subjected Irene to torture and public humilation after she began transforming into a dragon, all out of paranoic belief that she would become a monster like Acnologia, until he decided to execute her in cold blood despite her being pregnant with their child]].
** If Acnologia didn't cross it by [[spoiler:brutally killing Igneel in front of Natsu, then he definitely crosses it by spitefully and sadistically destroying Irene's corpse for creating the Dragon Slayer Magic]]. Erza and Wendy's horrified reaction at the latter just highlights it.

** Buli and Guli, a pair of Zeref cultists from the Tower of Heaven, crossed it in flashbacks, where they massacred several villages and kidnapped their children to use them as a labor force necessary to complete the Tower, going as far to subject anyone who resists them to the ColdBloodedTorture.

** Zancrow crosses it when he incinerates his own soldiers just for warning him about Natsu's strenght, only to go further when he reveals to Merudy that Ultear is the one who massacred her village.
** Jiemma Orland crosses it ''twice''. The first is when he kicks out Yukino for losing a match by having her strip herself naked in front of her guildmates and erase her guild mark. The second is when he [[spoiler:nearly]] [[KickTheDog vaporizes Lector]] [[EvilIsPetty for wearing the Sabertooth mark]].

** Similar to Jackal, if Ezel didn't cross it by massacring an entire village just to get one council member, then he crosses it by nearly eating Carla alive in front of Wendy.
** However, the two are trumped by [[BadBoss Mard Geer Tartaros]], who tortures Kyoka for wasting her time by torturing a human and sacrifices his own men when he traps Fairy Tail inside [[EldritchLocation Alegria]]. Even Kyoka is troubled by Mard Geer's willingness to sacrifice their own brethren.

** Invel Yura crosses it when he [[spoiler:forces Gray and Juvia to fight each other to the death, fully expecting Gray to win so that his inner darkness can awake and turn him into a warrior who can kill E.N.D. (i.e. Gray's [[VitriolicBestBuds friendly]] [[TheRival rival]] Natsu, meaning Gray would have killed two of his friends), an action that forces Juvia to perform a HeroicSuicide, since she doesn't want to kill Gray or have him live with the guilt of killing her]].
