Moral Event Horizon/Anime and Manga


 * As a Dark Fantasy series, Berserk has many villains that perform really sickening acts. Most of them are monsters in general, but in terms of crossing the Horizon, several characters stand out.
 * The choice to Sacrifice in general is a crossing of one's personal Moral Event Horizon. It entails taking the person or people you most love and killing them in the most nightmarish fashion imaginable, consigning them to a Cruel and Unusual Death at the hands of some of the most horrifying monsters ever to grace the pages of manga. This acts to cut you off from humanity and open yourself up to evil, facilitating your transformation into a demonic monster yourself. And as if this wasn't bad enough, it's also mentioned that those who get sacrificed in the creation of a demon not only die horribly, but their souls are condemned to an eternity in Hell. (Then again, considering the lack of mention of a heaven, it would appear that hell is the regular destination of pretty much everyone.)
 * Probably the biggest and most heinous example of this occurs during the Eclipse after Griffith crosses the Despair Event Horizon near the end of the Golden Age arc (which is about the point where the anime ends as well) and activates his Crimson Behelit. . And as if all this wasn't bad enough, Griffith then goes the extra mile across the Horizon with This is the king of moral event horizons in this series, and anime and manga in general. After this, Griffith acting like a hero when he is reincarnated on Earth tends to be just a little bit ironic.
 * Particularly because . Yeah.
 * Gambino, Guts's gruff mentor/father figure, loses all our sympathy after he sells Guts, who was just eight years old at the time, to a paedophile soldier named Donovan for three silver coins. Particularly when we learn Gambino's reason for it immediately before Guts kills him in self-defense—he called Guts "disgusting" and felt that he "can't be raised to be loyal like a dog," since Gambino blamed the kid for the death of his lover Shisu from the plague.
 * The King of Midland, who after ordering Griffith thrown in the dungeons and put to the torture for having sex with his daughter Princess Charlotte, tries to force himself on her out of madness. Charlotte just barely manages to fight him off, and the experience alienates her from her father, to the point where she won't even acknowledge him on his deathbed.
 * Don't forget how he basically orders the Band of the Hawk, a group that has done nothing but fight faithfully in his name, wiped out as punishment for Griffith's behavior, something they had nothing to do with, and sends a group of vicious killers (including a really nasty Apostle) after Guts and his friends after they rescue Griffith.
 * Inquisitor "Bloody Scripture" Mozgus is just as horrible as you'd expect a fanatical religious nutjob with too much power and not a shred of objectivity can get. While it's pretty obvious from the start that he's Bad News, when a band of starving refugees attempts to steal some of the ample foodstuffs sent to Mozgus and his retinue, he spots among them a woman with a starving infant. When she begs him to feed her child, he gently takes her along to his residence, lauding her courage and dedication. He sends away the child to be fed and cared for, then escorts her to a room while extolling the fact that while her intentions were good, she still has to expiate her sins... Then he opens the door, where we see the other refugees being horribly tortured, and the poor woman is dragged, stripped, and tied to another torture device over her increasingly frantic pleas... Then the door closes. It's as nightmarish as it sounds, if not more so.
 * Then you find out the kid dies anyway.
 * As bad as those are the worst has to be Emperor Ganishka. If you name it he has done it: ethnic cleansing, putting POWs on the front lines, wide spread torture, attempted rape (of Charlotte, again) to more horrifying examples like turning the Midland capitol into a city of death, using black magic to conjure evil spirits to fight for him forcing pregnant women into pits of chained apostles to produce demon soldiers who tear their way out of their still living mothers and finally using an artificial means to becoming an even more powerful demon that would destroy everything. All the while bragging about making the world into hell. He has not crossed the moral event horizon. He is the black hole causing it.
 * Just consider this: Post-Eclipse!Griffith went against him. And quite a bunch of fans actively cheered for him! How do you turn one of the most despicable bastards in the Berserkverse into an anti-hero? Pit him against this Adolf Hitler Expy!
 * During the Eclipse Slan a demon woman commenting on how delicious the whole ordeal of Casca getting raped by  is while Guts is forced to watch. She even sounds like she's having an orgasm and sheds a tear of joy.
 * Elfen Lied: When the cruel kids from Lucy's childhood forced her to watch as they beat the puppy that she had started caring for to death, just to get any kind of reaction from her at all, they crossed the Moral Event Horizon to the point that Lucy snapping and murdering them all by making their heads a splode in a Beware the Nice Ones moment was almost too good for them.
 * Lucy herself, when she after she has neutralized the threat she had posed. And let's not forget the . For that, Lucy spent the rest of the series trying to be The Atoner to  . Plenty of people thought that there could be no atonement for it.
 * Some would also include Lucy
 * killing Satoko in the Meakashi-hen arc of Higurashi no Naku Koro ni and forcing to watch. Even she admits that she's pretty much beyond all salvation at that point.
 * was on the receiving end of one of these, being tortured by her own Yakuza family It also serves as a crossing point for Onryu to the point where Mion considers.
 * We all knew Teppei was a child abuser, but when he kicks and throws around his niece Satoko onscreen while she is crying and begging him to stop, that's when it really hits home.
 * Let's not forget Rina Mamiya, who not only gleefully contributes to Teppei's schemes, but
 * at the end of Minagoroshi-hen. Not only killing a 12-year-old girl in cold blood, but psychologically torturing her into believing she might have had a chance to live? She might have needed Rika to die, but killing Satoko was pure evil. The anime then goes on to try and whip up some sympathy for  by showing her childhood sob story, which, to be honest, is quite terrible. But it still doesn't make her any less evil when that unlucky little girl grows up to be such a monster.
 * Tetsuo crossed one of these himself. Tired of having to be rescued by Kaneda and wanting independence, he felt ecstatic when he developed superpowers while in custody of the millitary. When Kaneda does arrive to rescue him, and military soldiers show up, he blows them away, hurting Kaneda in the process. Instead of showing any sympathy for him or sorrow for what happened to him whatsoever, he just laughed and said "Oh, that's right. I forgot you were there!" And boasted on how he won't need to be rescued anymore, even proceeding to attack Kaneda again... this time on purpose! Attacking your own friend with NO remorse!? That's just wrong.
 * And when I say he laughed, I mean that it was a MANIACAL CACKLE!
 * And just to drive home the point that he's too far gone to be saved, he later BRUTALLY murders his former friend Yamagata.
 * In the manga, crosses it by
 * Neon Genesis Evangelion has Gendo Ikari, leader of NERV and Shinji's Jerkass father, cross the line when, following Shinji's refusal to destroy an Angel-possessed Evangelion Unit-03, he activates the Dummy-Plug system to carry out its destruction, nearly killing its pilot Toji Suzuhara, Shinji's classmate and friend in the process. All as his son is screaming at him to stop making him fight against his will and Gendo can clearly hear him over the transmission but does nothing. It's worse in the manga adaptation because Toji actually dies from the wounds that Shinji is made to inflict upon him.
 * While the Human Instrumentality Project is twisted enough, Keel Lorenz and the old men of SEELE truly cross the line in End of Evangelion when, having deemed NERV and the Eva Units past the point of use to them, they send the JSSDF to slaughter everyone at NERV Base, and also send in their own mass-produced EVA Units to kill Asuka, a 14 year old child, in a merciless and gruesome manner.
 * Naoko Akagi was a real piece of work to start with, but when she strangled the first Rei Ayanami, a small child, to death with her bare hands, in a jealous rage all because Rei had repeated unflattering words about Naoko that Gendo had said in front of her, she went over the line. And she seemed to recognize it, given what came next.
 * It's debatable if the Angels are even capable of crossing the MEH given their nature, but the last couple of Angels do some downright unforgivable things: Arael's notorious Mind Rape of Asuka in episode 22, Amishael's sexual penetration, Mind Screw Breaking Speech, and destruction of Rei II and Unit 0 in episode 23, and Adam/Lilith/Giant Naked Rei utterly breaking Shinji's psyche to the point where he sets Instrumentality in motion in End of Evangelion. And VERY arguably, Tabris/Kaworu befriending Shinji despite knowing that one would have to kill the other eventually played a big part in making that last one possible.
 * In Tengen Toppa Gurren Lagann's second movie, Lagann-Hen, the analyzes and dissolves Nia... By mounting her naked body and grasping her with tentacles. At that point, he stopped being a Well-Intentioned Extremist and started looking like a reject from Legend of the Overfiend.
 * Gantz has its share of these folks:
 * , already established as a major-league Jerkass,
 * Well, to be fair,
 * He outdoes himself in Chapter 184
 * arguably crosses the line when
 * Take into account the large amount of evidence that Gantz doesn't revive people, he recreates them (with the possible exception of Tae Kojima, whom he pulled into his memory banks before she actually died). Whether or not the Old Man was brought back, the original would still likely be dead.
 * Perhaps Nakago of Fushigi Yuugi had crossed lots of these before and throughout the series, but the most jarring one is when . It hurts even more when you realize that.
 * Let's not forget that Nakago is STILL to blame for that one.
 * In One Piece, the World Government re-enacts the Massacre of the Innocents  That and the following below, will probably earn what should be the good guys in the story, a likely overthrow
 * "Normally, carpenters are not charged for the ships they construct, but this is in regards to the Pirate King. This is a special case. All those who supported his piracy, even a little, will be seen as dangerous."
 * We also have the World Nobles. They're descended from the founders of the World Government, which gives them a carte blanche to treat their lessers as they see fit. They are introduced to the readers when two of them are seen sneering at a slave who was wounded after trying to escape from them, kicking him and shooting him several times. Then one of them commented how his captain collection was now ruined and tells the other that she's getting a child slave, not the giant slave she wanted.
 * The third one was seen riding a man and kicking him the head for not going fast enough. When a doctor and a nurse were trying to get to the hospital to bring in an injured man when they should be bowing to him, the World Noble simply kicked the injured man to the ground. When he saw that the nurse was a beauty, he promptly named her his newest wife, and when her fiancee stood up to him, he shot him and dragged the crying nurse away.
 * Later, he wanted to buy Camie, just to see if a mermaid could out-swim his tank full of piranhas. And when Hachi arrive to try to save Camie and is exposed as not human, he shot Hachi, just because, and gleefully declared how he had shot a fishman in front of Camie and a whole audience and how he got this fishman for free.
 * The audience (excluding the pirates) were just as bad. They started laughing at Hachi and saying how thankful they were that someone had shot the monster.
 * Vice Admiral Onigumo. He has no problems about killing his subordinate and over a 1000 other marines as long as he kills manages to kill the pirates.
 * Admiral Akainu definitely takes the cake here. In his debut, he orders the destruction of a civilian ship, all because it might just contain an escaped archaeologist. He would then show up later to execute a lowly mook, after he saw how outclassed he was fighting with the upper class pirates and marines at Marineford, for just wanting to go home and be with his family.
 * A few chapters later,
 * Captain Kuro spent year after year after year posing as a man named Klahadore and serving as the butler to Kaya, whose father had supposedly saved his life and let him work there. Since Kaya's father passed away, Kuro became the closest thing Kaya had to a father figure, and the two of them did many things together. Turns out, Kuro was biding his time all for the day when he could kill Kaya and claim her inheritance money, which he'd use to retire from piracy for good. The real sick part? Killing Kaya wasn't truly necessary - Kuro wanted to do it for peace of mind, because he'd secretly hated Kaya all these years, finding tending to her whims to be degrading! And he tells this all right to Kaya's face when confronted about it, leading to a big Break the Cutie moment that rightfully enrages Usopp. It's no wonder Kuro is deemed irredeemable.
 * Arlong is far over the line. Even after we find out that he killed Nami's adoptive mother for not having the money to pay a toll that he just imposed on the town, it looks as if he's at least willing to let Nami work to buy her town back. So he lets her join his crew and work tirelessly for eight years to earn the 100 million beri that she needs to meet his price by going out and robbing pirates on the side. And then, when she only has one voyage's worth of money left to earn, he sends a corrupt Naval officer to steal all of the money she worked for eight years to collect. And when she confronts him about it, he has the gall to simply smile at her and ask "What promise did I break?". And then? He laughs.
 * The latest is practically the entire city of Goa:
 * Hody Jones, a member of the Big Bad Duumvirate in the currently ongoing Fishman Island arc, proves himself to be even worse than Arlong!
 * But wait, there's more! . It is at that point that you can be sure that all the preaching he has done up until that point is pretty much a lame excuse for wreaking chaos.
 * Oh, it gets even worse. Shortly after the above, he  This wouldn't be much of a problem... if it weren't for the fact that   for shits and giggles.
 * Speaking of which, Van Der Decken is no better than Hody. For one thing, he willingly partnered with Hody to overthrow Fishman Island's monarchy, with the side benefit of getting Shirahoshi for himself...and when Hachi (a former ally of Arlong, who Hodi held in high regard) tried to persuade them to call off their plans, what was Decken's response? . Oh, and let's not forget.
 * For the longest time, even after it was revealed they ordered Ohara burned to the ground, some fans were willing to give the Five Elders a pass. After all, they were trying to protect the world from ancient weapons of mass destruction. Then came the ending of the Marineford Arc, in which they order the escape of many vicious criminals from Impel Down covered up, and it became apparent that they're more concerned with their own power and image than protecting the world. This one was so bad, Sengoku and Garp resigned on the spot rather than work for a government that would condone such things.
 * In Naruto, Sasuke Uchiha has clearly crossed the horizon, but being one of the primary protagonists makes it far less likely to stick. He's done morally questionable things like: attacking Killerbee (a man that has never wronged him), killing all the Samurai guarding the Kage Summit and abandoning Juugo and Suigetsu, but finally cemented it when
 * Then there's Tobi, whose most despicable acts include: his actions in the Uchiha Clan Massacre, where there was a very good chance that he was using its then-leader Fugaku (Itachi and Sasuke's father) and starting the Coup all in an attempt to get his former Clan killed off-and it works, since Konoha's elders were forced to kill them off using Itachi Uchiha against them. It is later revealed he killed the ANBU guards protecting the place where Kushina Uzumaki was giving birth, then killed Taji and Hiruzen's wife Biwako and took Naruto, who was only minutes old at the time hostage, threatening to kill the newborn unless Minato handed over the Kyuubi so he could attack the Hidden Leaf. He then tops himself again in the next chapter when
 * Kabuto Yakushi was always a very shady figure, but had not super crossed the MEH. Until now, when  Not even   likes such things...
 * And let's not forget what he does to  after defeating her in combat:
 * The Fourth Kazekage crosses the MEH with his treatment of his son, Gaara. He has a demon sealed into the boy at birth, completely isolates him from his family save for his uncle Yashamaru.  And when the emotionally fragile, socially isolated child reacts badly to the fact that no one's ever loved him, he decides to have the kid murdered. No wonder Gaara turned out like he did, at least until Naruto intervened in his life.
 * Fullmetal Alchemist: Envy. Oh sure, we'd known from his first appearance that he's evil and will kill you if it's amusing or he's ordered to, but one of two scenes becomes his Moral Event Horizon crossing, depending on who you are:
 * For some, he irreparably crossed the line when he after turning into   to keep him from striking back, and triggering some of the series' biggest Tear Jerkers.
 * And if that didn't do it for you, there's still no way you can put this guy in leather pants (at least not without people questioning your sanity) after he gleefully describes in the manga how he by turning into a war-opposing soldier and shooting an innocent child. His absolutely cheerful description of the events that happened after he shot the child, how it ruined the life of the soldier he turned himself into, and how humans are so easy to manipulate revealed him for the monster he really is. What he said got Ed so angry that he punched Envy in the face so hard that Envy's face had to regenerate immediately afterwards.
 * Let's not forget Shou Tucker. He is so twisted that he turned his own five-year-old daughter Nina into a chimera by fusing her with their pet dog Alexander, creating a horrible abomination whose entire life consisted of pain that would later have to be mercy-killed by Scar. While the main reason he did this is because he was being pressured that without "interesting" results from his experiments, the government would kick him out, Tucker later admits that he "didn't have a reason", and eventually would have gotten around to doing it just to prove he could. Apparently, this isn't the first time Tucker did that either - he also transformed his wife into a chimera, and she succumbed to Death by Despair.
 * "Doctor Goldtooth" from the manga spends most of his screentime crossing the Moral Event Horizon. He's responsible for experimenting on people to make human-based homunculi; except for the one who became, all of the subjects died or were rendered mindless and used as Elite Mooks, and he later   He does so without any remorse or regard for human life, and it's thus very satisfying to see him
 * Father from the manga and second anime
 * Dante, the Big Bad of the first anime, who creates and maintains a military dictatorship and has her minions, the homunculi, go around stirring up conflicts and encouraging people to engage in forbidden alchemy and human sacrifice — all for one goal, to create the magic stone that will allow her to keep on living forever. Not to mention there's how
 * Pride from the first anime plows right through the Moral Event Horizon at the end of the series when he remorselessly for bringing his remains (having no idea what they really were) to him during his battle with Roy.
 * from Bleach has had many of these. The most recent, and arguably the worst of them all?  So brilliant. So cruel. Guess he'll still have his leather pants on, though.
 * Many readers consider Mayuri Kurotsuchi to have crossed the horizon when he tortured Ishida's grandfather to death along with over 2000 other Quincy, and then showed Ishida a photo of his grandfather's corpse. Keep in mind that he had no idea of Ishida's relationship with his grandfather at that point, he just showed the photograph to him to taunt him.
 * And he's still outdone by his even more Evil Counterpart, Szayel Aporro Ganz. Not only he takes delight on torturing Renji and the aforementioned Ishida slowly and painfully, but when Kurotsuchi and his lieutenant Nemu arrive to face him, just as Kurotsuchi is about to defeat him he  This is so squicky and cruel that a good part of the fandom saw   as something to cheer for.
 * Yammy was always an ass, but he really crossed the line when he killed the nurse that reattached his arm.
 * Nnoitra does this when he hints he intends to rape Orihime at some point (he stuck his fingers deep in her mouth in the manga for crying out loud), and in the backstory, his hatred towards Nel led him to collaborate with Szayel so he could take away her powers because he was jealous of her for being stronger than him and then he kicks her out of Hueco Mundo. Not to mention, he immobilized Orihime and forced her to watch as he has his subordinate Tesla beat Ichigo to death. Thanks to a Big Damn Heroes moment by Kenpachi, however, Ichigo is safe and Orihime heals him.
 * We also have  conspiring to cross the MEH with each other's help. The first , and the other   Horrible and brilliant at the same time.
 * Made even worse/better/etc. when  This is what happens, as  . Eeeeeugh. That one was so un-needed that   told him to cut it... bringing up Fridge Horror as he strongly implies
 * Subverted in the case of . He gleefully claimed to have crossed this via , but   quickly deduces (and shows!) that he wasn't as heartfelt and happy about it as he believed,
 * The Big Bad of the final arc, Yhwach, crossed it in his backstory. In order to augment his own power, Yhwach power-drained and thus killed off the "Gemischt" and "Echt" Quincies regarded as "impure".
 * Freezing has Louis L. Bridgette, the leading female's half brother. Sure, it was sick that as a kid, he had a creepy fondness for touching Satella that led her to having severe issues, and everybody in the forums were clamoring for his castration. But now?  Seriously, WTF.
 * Mark Spencer, the head of the Chevalier and overseer of the E-Pandora project.
 * Several Pretty Cure villains "parked in the red zone":
 * In Futari wa Pretty Cure Splash Star, Lord Akudaikahn, and Gooyan.
 * In Yes! Pretty Cure 5, Girinma.
 * In Fresh Pretty Cure, Cline, and Northa tries brainwashing Setsuna back into Labyrinth, pressing Love's Berserk Button in the process.
 * In Heartcatch Pretty Cure, Dune.
 * In Suite Pretty Cure, Mephisto brainwashes Siren.
 * Light Yagami of Death Note has his at varying points in the story, his first coming very early in the story when he kills Lind L. Tailor. They just get more and more extreme until If Light still had fans by that point, they were gone after that.
 * Horrifyingly, no, they weren't. Some rabid fans even LIKED to see him . Others simply agreed with his morality and methods.
 * An argument can be made that he crossed it even earlier, when he started killing people already facing legal justice for their crimes. At the beginning he was intervening in crimes in progress (specifically, hostage-taking and sexual assault), and cleaning up after the justice system's failures a'la Dexter is somewhat forgivable, but negating its successes and attempting to make the entire criminal justice system completely worthless is doing more harm than good.
 * Special mention needs to go to what Light does to  because this is a) The first time he murders a character that is unambiguously good and still have the nerve to childishly gloat about it. b) He   and c)   Seriously, Light
 * When  is on his deathbed, does Light care? Nope, he just wants to know Mello's real name.
 * In the Live Action Adaptation, Light crosses this (in addition to some of the above examples) either
 * Quite a few Yu Yu Hakusho villains have fun crossing the horizon, some of them being Complete Monsters. Three of them are particularly extreme examples, though all of them get what's coming to them.
 * Gonzo Tarukane had Yukina belittled and tortured just to produce the valuable gems her race produces. And gets killed by Younger Toguro.
 * Suzaku commanded all the humans under his control to hunt down and kill Keiko, then tortured Yusuke and forced him to watch Keiko and Botan get nearly killed. Yusuke nearly gives up his life energy to kill him.
 * The first super example is Elder Toguro, who happens to cross the MEH twice. The first time, he brutally impaled Kuwabara over and over again, slammed him to the floor from extreme heights, then attempted to break his psyche by using his morphing powers to recreate a sickeningly twisted version of right in front of Kuwabara, who didn't know. The second time is when he, and took insane pleasure in doing it. Luckily he got what he deserved thanks to Kurama..
 * The second of the extreme examples is . He also gets what he deserves, due to a combined effort between Kurama and Hiei..
 * There's a third extreme example we're forgetting. Remember Dr Ichigaki? If you don't, let me remind you:  Therefore, it's a HUGE relief to see
 * A good example of a dog-raping that pushes you over the Despair Event Horizon is when, which is exactly what happens to Yurippe in a flashback in episode 2 of Angel Beats!.
 * Yuri herself almost crosses the line in the manga by The scary thing is, she would've done so then and there had Hinata not intervened before the first murder was supposed to take place.
 * She comes close to crossing the line once again in Stairway to Heaven, and we mean DANGEROUSLY close, by . In fact, that may be the closest she's EVER come to the MEH. That doesn't stop her from being redeemed by the end of the main series, though.
 * Almost everyone in School Days crosses this at one point or another.
 * Makoto Itou: Pick your poison, but one good choice is
 * Sekai Saionji:, natch. Of course, it only counts because the way it's carried out it's basically Disproportionate Retribution for being a major asshole for much of the series. Other than that, it's more forgivable than the others' atrocities, since at least she has an excuse for it (see the spoiler for  MEH for more on that).
 * In the manga, In that one, she has next-to-no excuse.
 * Kotonoha Katsura:, plus the contents of her bag...
 * Taisuke Sawanaga:
 * Natsumi Koizumi, Kumi Mouri, and Minami Obuchi: Taking advantage of a school tradition to, just for the lulz. The victims include: Sekai's friend Nanami, , and their supposed friend Otome who is seen , AND whose feelings they then ignore again by.
 * In Wolf Guy Wolfen Crest Haguro Dou manipulates the younger Kuroda into going Columbine on half the student body out of vengeance against Inugami for his brother's death. Using weapons from his family gun cellar. The kicker? His brother died because HAGURO pulled his life-support.
 * Also, Haguro beat his subordinate Chiba within an inch of his life, biting off his tongue, and then raping him for good measure to the point that Chiba ends up dying from a combination of ruptured organs, blood loss, and broken ribs. . Why did Haguro do such a thing? Because Chiba ended up encountering Inugami out on the streets and talked to him for maybe 15 minutes when Haguro wasn't around. Haguro is Yandere for Inugami's werewolf form, you see.
 * He and his goons gangraped Aoshika (a teacher who ends up falling in love with Inugami, and became his Morality Chain) while recording it so that Inugami can see, practically talking to the camera (and, therefore, to Inugami) through the entire thing in the hopes that Inugami (who left due to Haguro's actions) will come back to him.
 * No, he didn't only rape her. Haguro also gave Aoshika a Psycho Serum that warped her mind so throughly that she enjoyed her own rape. All to break her further and have "revenge" on her for daring to attract Inugami's attention. No wonder she thinks she's been Defiled Forever and it takes Inugami a LOT to give her back a little bit of hope.
 * Haguro also fired an MGL-140, which is a semi-automatic grenade launcher, at the school. Thus committing the SECOND school shooting of the series. The attack hospitalizes Aoshika, and she later identifies him as the shooter. Long story short, there's a very good reason Haguro is considered a Complete Monster.
 * While minor compared to her "boyfriend" Haguro, Ryuuko Kounuma also crossed the MEH via selling out Aoshika to Haguro in her wish to not be used as a bait for Inugami, in what can be easily interpreted as making sure Aoshika will be either super-broken or dead as retaliation for Inugami liking her more than Ryuuko.
 * And then there's when Haguro tries to kill Aoshika because he thinks Inugami's too good for her right after practically ruining her life with the abovementioned gangrape and when Inugami shows up to stop this, Haguro slices off Inugami's fingers, eats them, and gets a boner for managing to hurt him, before slicing off his arm and attempting to kill Inugami.
 * Vamdemon/Myostismon was the Digimon series's first Really Big Bad. If his string of Kick the Dog moments - he tortures and kills his Mooks, he captured Tailmon/Gatomon when she set out looking for her partner on her own and literally whipped her into a Child Soldier, he has his followers invade the entire city of Tokyo and kidnap its children to weed out the eighth Chosen One, and that's for starters - don't gradually nudge him over the Moral Event Horizon, then Wizardmon's child-scarring death - taking an attack meant to kill Tailmon and Hikari, by the way - certainly does. It makes it downright beautiful when the fact that Vamdemon just made it extra personal to Tailmon and, by extension, Hikari triggers Tailmon's evolving into Angewomon and impaling him with an arrow. Even that doesn't stop him, however, and he gets even worse.
 * Piedmon crossed the line multiple times over. Genocide against the Digital Guardians, skewering poor Chumon, massacring Primary Village (which is filled with Digi-eggs of baby Digimon), turning the kids and their Digimon into keychains, and trying to outright murder the two youngest children by cutting the rope they were climbing are all things he did and took sadistic joy in doing.
 * While he wasn't as bad as Myotismon or Piedmon, Puppetmon crossed his MEH when he threatened to kill Yamato if Takeru didn't come with him...and then tried to kill the kid with a freaking gun. And if that one's arguable, then killing one of his own underlings who was begging him to take him with him is definitely going beyond the pale.
 * Machinedramon's pretty vile too. His most likely MEH moment was killing the hoard of Numemon that were trying to protect Kari by blasting them all.
 * If you think all that's bad, you haven't seen Digimon Savers. Take Yamaki, multiply his hatred of Digimon by a thousand (or more), take away his guilt, and then add in a bloodthirsty desire to kill all Digimon (not just the ones that form in the Real World) and take over the world by threatening to have the Real World and the Digital World collide, thereby destroying both. Then you have Kurata.
 * To put it in even more perspective, Well-Intentioned Extremist Yamaki, while trying to force the Digimon out of the Real World, came up with a method that probably killed them. He then used it, realized in utter horror that he had basically made it worse, and not long after did a Heel Face Turn. Smug Snake Kurata specifically made a machine to destroy Digimon permanently and then used it. Upon realizing that he had made it worse, he made it even worse.
 * Kouki from the same series had no qualms about holding an entire city hostage, not caring about the thousands of lives lost. His comrade Nanami kills Digimon out of a desire to fill a lonely void in her heart, and his other comrade Ivan is doing it to get money for his family. Kouki? Does it For the Evulz.
 * MetalPhantomon also crossed it by using the DATS agents' worst fears and memories against them in order to suck out their life energy. Thomas got it particularly bad.
 * In Digimon Tamers, Beelzemon stepped right on to the MEH, particularly in Takato's eyes, when he . If Gallantmon had been allowed to finish Beelzemon off at the end of their fight, we'd probably have thought him to be beyond redemption. But when Juri asks Gallantmon to spare him since she doesn't want anybody else to die, he does a Heel Face Turn and becomes The Atoner.
 * Yamaki spent a lot of time walking along the line, too. He had an innocent Digimon tortured to death for information, coldly says that Digimon are "just a bunch of numbers" and thus morals don't apply to them, and tries to destroy every Digimon in the world including the heroes twice. Like Beelzemon, he has a My God, What Have I Done?, backs away from the line, and undergoes a Heel Face Turn.
 * What, no D-Reaper? While it was just doing it's duty in the digital world, it crossed the line when it followed the heroes back to the real world, possessed and mind-fucked a depressed little girl, emotionally tortured said girl to make her even more miserable, and fed off her misery. Unlike the above two examples, there is no redemption for this thing.
 * Charon from Pokémon Diamond and Pearl Adventure accomplishes this before he even shows up, by ordering some of his Mooks to suicide bomb the Pokémon League tournament.
 * In Pokémon Special, Ghetsis was already on the line due to, but his moment officially comes after Black has defeated N. This cemented Ghetsis' status as the vilest villain of the series to date.
 * The story of the film takes absolutely no effort to hide that Kodai from Pokémon: Zoroark: Master of Illusions is a Complete Monster, but the point he really crosses this may vary from person to person. However, the most likely is when he freaking electrocutes a baby right in front of its mother. Unlike the other horrific things he did, this is really the first time he's shown doing something terrible that didn't have anything to do with his plan, as Zoroark stopped attacking the moment she saw he had Zorua. He even comes right out and says he enjoyed it directly after that. Furthermore, he   and choked out Celebi! That said, his Humiliation Conga was  extremely cathartic.
 * Paul from the anime itself also crossed the line. For those who don't understand, he's gone through at least three regions discarding Pokemon that fail to live up to his standards, however flimsy the excuse would be (even in comparison to how he started, which was his brother shifting gears into becoming a full-time Breeder after choking to Pyramid King Brandon). He also has little sympathy or tolerance for failure in combat, displayed in his first onscreen battle with a Starly he released after said fight anyway! It particularly crystallized during the infamous Tag Tournament, where Paul had all his other Pokemon assault Chimchar the night before the final round, had Chimchar use attacks with no regard to friendly fire during the actual battle, refused to have it healed prior to the battle, ragequit when Zangoose came out to play, and released Chimchar afterwards, who predictably ran crying to Ash.
 * Cyrus from Diamond and Pearl arc of Pokemon anime crosses this line is when he orders Mars to blow up Iron Island, which is full of Pokemon and people living there just to prove a point about interfering with Team Galactic's great designs- sporting a Slasher Smile whilst giving that order.
 * His entire plan to destroy the universe and remake in his own image and measures he takes to accomplish it (like attack on Celestic Town or aforementioned Iron Island) qualifies for him.
 * Pokémon Hunter J is always a Complete Monster in all of her appearances, but in the "Pokémon Ranger and the Kidnapped Riolu" two-parter she really shows her cruelty when she tries to murder Ash, (a 10 year old boy), several times. First she orders her Salamence to burn the surrounding forest and fire Hyper Beam directly at him, then has her Drapion squeeze him tightly, and finally ejects him from her ship at great height. She also says that she wanted to punish Ash personally and took pleasure in trying to kill him and everytime she attacks Ash she is shown with a Slasher Smile.
 * Damian, Ash's Charmander's former trainer was already mastering Kick the Dog by abandoning Charmander after promising he'd come back, and then bragging about this to his friends. But he crossed the MEH when he refused to come back for Charmander when it began to rain and Brock straight up told him that rain would make Charmander's tail flame go out and it would die.
 * Similarly, Tepig's former trainer Shamus abandoned Tepig by tying him to a post and leaving him behind at the Battle Club. While a nasty action to take, he had told Tepig that he felt it was for Tepig's own good that he not be his Pokemon anymore and that he was remorseful for having to do it.
 * Lord Ghetsis of Team Plasma in the Episode N arc of Best Wishes crosses the line when he orders a mind-controlled Reshiram to incinerate everyone currently at the White Ruins...which included several members of his own team! Team Rocket even calls this out as being self-centered and deplorable.
 * Dr. Katsuragi of Sakura Gari is pretty fond of doing this. Not only is he a disgusting pedophile, he drugs, rapes and tortures Masataka (this includes whipping him and sticking a household object up his anus right after raping him) and holds his hand in boiling hot tea because of his jealousy over Masataka being the one Souma loves (when he loves Souma to an insane degree himself) and he beats his Woobie wife Asayo. Oh, and in the backstory  When Souma confronts Katsuragi on his rape and torture of Masataka, Katsuragi denies the accusation and tries to seduce Souma. He acts uninterested and mentions Masataka's name, so Katsuragi actually grabs Souma by the throat and tries to strangle him.
 * Blood Plus: Diva crosses it when she rapes Saya's younger brother Riku so that she can bear his child, and then kills him.
 * Hellsing: Zorin Blitz crosses it when she lays siege to the Hellsing Mansion with her forces, mind rapes Seras by delving deep into Seras' memories, forcing her to relive her painful childhood, where she had to watch her parents be murdered by gangsters and her mother's corpse being raped. While Seras is trapped in the illusion, Zorin hacks off her arm, stabs her through the back, and cuts her eyes. Bernadotte and his two remaining squad members arrive and manage to temporarily disable Zorin by shooting her multiple times and Bernadotte tries to escape with the badly wounded Seras, but Zorin kills him by stabbing him through the back with her scythe. To top it all off as Seras cradles Pip's dead body and cries for him Zorin mocks Pip calling him an "insect" and prepares to kill Seras and her fellow team members. This was enough to provoke Seras into absolutely curb stomping Zorin and her forces to death.
 * The burglars from Seras's past definitely crossed the MEH. Seras, who seems a cheerful and upbeat girl for most of the manga, has a rather dark and disturbing backstory, which seems to have happened when she was very young. It consists of her father being murdered by burglars, her mother hiding her in a cupboard to protect her, and her mother's subsequent murder by the same burglars. Seras tries to exact revenge by stabbing one of the guys in the eye with a fork. She gets shot for doing so and one of the perpetrators proceed to rape her mother's corpse, due to it being "still warm". In full view of Seras who lies on the ground bleeding profusely watching it happen and unable to do anything to stop it.
 * And Enrico Maxwell's got one too! When he started slaughtering the innocent people of London, even his trusted Alexander Anderson considered him to be an absolute lunitic.
 * Gankutsuou: Arguably,  Interestingly, this marks a significant difference with the novel,
 * Let's not forget Andrea Calvacanti
 * And She seems perfectly normal in her first few appearances, with a warm motherly appearance and pleasant smile. She is the stepmother of Valentine and is the second wife of the crown prosecutor Villefort. She is the biological mother of her young son Edward, from her first marriage; however, Valentine is to inherit all of the fortune, leaving her stepmother jealous because Edward doesn’t get a single penny.  And she does all this while maintaining her angelic motherly facade  Not to mention the scene where
 * The Defence Minister of Simulacrum in Simoun desecrating the corpse of an enemy priestess, having his goons rough up Yun and mock her religious devotion when she objects, overruling the heads of the Simulacran church to deny a proper funeral, and trying to prevent the sibyllae from giving their fallen friend the most basic memorial service possible, all within the space of two and a half episodes. When it comes to tension between religion and laïcité, Simoun knows what side its bread is buttered.
 * Swordfish does this a few times in Under Grant Hotel but the most notable example would have to be him basically raping his lover Sen to almost death when Sen said something that annoyed him.
 * Highschool of the Dead has quite a few, but some of the worst offenders are from the secondary and tertiary characters. One incident sees two Red Shirts, Misuzu Ichijo and Toshimi Niki, running through the halls of their zombie-infested school, Holding Hands together and saying they'll survive together because they're BFFs. Not even five seconds later, Toshimi literally runs into a horde of zombies and begs Misuzu to pull her away from them, only to have her hand remorselessly pried off. As Misuzu watches Toshimi get devoured, she stumbles back into another group of zombies behind her, and her head is crushed just as quickly. Although in the anime, she may have regretted her action just before her own death.
 * A better example would be the nutjob who went crazy (and even explicitly admitted to being a psycho) after being forced to kill his entire family when they got bitten. That doesn't excuse the fact that afterward, he tried to kill both Takashi and Rei (and rape the latter) at a gas station. Satisfying doesn't even begin to describe how Takashi deals with the bastard.
 * Oh, and don't get me started on Shidou and his followers. And while Shidou's father isn't as complete a monster as his son (who admitted to wanting to destroy the entire Shidou line, himself included), he still gets his MEH when he instructs his son to rig Rei's grades, knowing full well that Shidou would do anything to make a student's life miserable (is it any wonder that Kohta snapped and yelled at him before he, Saeko, Saya, and Shizuka escaped from the Orgybus?).
 * Even the protagonists themselves have stated that they're willing to cross it if that's what it takes to survive as long as they can. Takashi and Saeko themselves have already crossed the MEH in their own respective personal opinions: Takashi, when he killed Hisashi partly out of jealousy over Rei; Saeko, by using herself to bait a would-be rapist into getting brutally and viciously attacked by her. Rei herself comes close when she's given the opportunity to summarily execute Shido at the Takagi mansion, but she ultimately averts this when she decides he's Not Worth Killing.
 * Yu-Gi-Oh! Dartz from the DOMA arc reached his Moral Event Horizon when he started killing off the protagonists, but the most horrifying example and crossing of his MEH is when the identities of the Mirror soldiers are revealed to be everyone's favorite characters: Joey, Mai, Yugi, and Pegasus. From then on, he used them as frikin' HUMAN SHIELDS. This was a true Kick the Dog moment to not only the remaining protagonists, but the entire fanbase as well. This Troper knows a few people who broke down crying because of this act.
 * Pegasus himself, though just as tragic as his anime counterpart, lost the sympathy of several readers of the manga when he telekinetically forced Bandit Keith to commit suicide, and would have fully crossed the line if Bandit Keith wasn't an Asshole Victim who was threatening Pegasus' life moments before. The anime changed this to simply having Keith dumped into the sea in a classic No One Could Survive That, and wouldn't you know it, he does.
 * His treatment of the Kaiba brothers might have already put him over the line. Even Yugi determined that This Is Unforgivable!
 * Another from the manga is the entire Death-T arc for Seto Kaiba. From hiring a Serial Killer who exclusively kills children to kill Yugi and his friends, to abandoning his brother, ostensibly his Morality Pet, to go catatonic from a penalty game, it's no wonder Yugi punished him by shattering his soul to pieces and rebuilding it from scratch: if he hadn't, there'd be no redemption for the scumbag. The later, Anti Heroic Kaiba who would be more familiar to those who saw the anime first is thus a completely different person.
 * Dark Marik immediately crossed the horizon when he tried to stab his foster brother in his sleep, and then proceeded to lay down a brutal, psyche-damaging Mind Rape to Mai in their duel.
 * Dark Bakura crossed the line with his plan to resurrect Zorc into the mortal world in the final arc, hoping to kill everyone and cast the entire world into darkness and destruction.
 * Zane Truesdale (Ryou Marufuji) in the second season of Yu-Gi-Oh! GX crosses the line after donning his Dark Kaiser persona when.
 * In Katekyo Hitman Reborn, possibly the most ludicrous example on this page is that is condemned by many of the fanbase after   Mind you, it's the whole family that's condemned, not just   And considering that Yamamoto is a main character,   so it's pretty unreasonable for so many fans to say that   should die.
 * Fortunately for them, the entire group is pretty much a team of Draco in Leather Pants, all of them having their own loyal fanbase who still loves them. Some of the fans who want them dead have admitted that they'll likely come crawling back to them after they (presumably) befriend the main characters.
 * If Redda didn't cross this line when he, he Kicked the Dog big time when he  . About Rokuna, it would've been bad enough if he just slaughtered her outright, but the way she would have died if Mondo and Zaha failed to save her would have been the most horrific way to die anyone could imagine.
 * Magical Girl Lyrical Nanoha always does her best to understand and even help her enemies, and after StrikerS, the cast is comprised almost entirely of ex-foes. That being said, when there's a character that can't be befriended, they really can't be befriended. Precia Testarossa crosses the line by mercilessly beating her 9-year-old daughter into a state of near-unconsciousness, and then later crushes her only reason for living. Twice.
 * In season 3, Jail was completely fine with anything, so long as it justified his research into cyborg bioweapons. Although he never explicitly crossed the line, his tendency to laugh maniacally while watching people suffer put him past redemption, even by Nanoha standards. Quattro, however, did cross the line when she strapped an innocent child up and tortured her into almost insanity to power her Cool Starship, and then forced her to try and kill her adoptive mother with her bare hands, while taunting them both. Quattro was punished accordingly.
 * Jail actually gets to cross the MEH when we learn the real reason why he treated the Numbers right. His escape route in the event of things going horribly wrong involved impregnating the Numbers Cyborgs, some of whom were made using his own genetic material and all of whom he had raised as his own daughters, with rapidly-growing clones carrying copies of his mind. Eeeeeeew. And let's not forget his really cruel attempt to Break Them by Talking with Fate either, taunting her with her memories of Precia's already mentioned MEH crossings and accusing her of being Not So Different.
 * In Force, Cypha crosses the Moral Event Horizon by admitting to killing dozens of civilians without any hint of remorse.
 * While many of the villains in Dragonball Z do some pretty horrific things, Frieza may just top them all, between his genocide of nearly the entire Saiyan race (and later, temporarily, the entire Namekian race) and his murders of Dende and Krillin, the former of whom was a child, and the latter of which sets off Goku's Super Saiyan transformation, leading to Frieza's undoing.
 * The anime added one of these that wasn't in the manga. In a very early appearance, Vegeta deposes the evil dictator of an alien planet. Now, that's hardly evil, but it turns out he did it purely to screw with the planet's inhabitants by giving them a Hope Spot, because the very next thing he does is wipe out the entire alien race. This became a problem when, over two years after the episode aired, the writer of the original manga had that same character pull a Heel Face Turn. Now, there was no way the anime staff could've known this, but it ended up making his redemption seem entirely unbelievable to many people who had only seen the anime.
 * Cell crossed it with the absorption of innocent people, slowly absorbing Android 18, destroying populated islands, sicking his clones on the Z fighters, and smashing Android 16's head in, killing him and thus earning the subsequent beatdown from Gohan.
 * Super Buu going on his genocidal Human Extinction Attack in which he destroys every last human on Earth. Kid Buu tops this by destroying the planet itself!
 * In the Liar Game, manga, Until then he could have just been someone with a traumatic childhood or someone really evil, but then he just becomes a complete monster.
 * in Macross Frontier has a number of candidates, with conducting painful, potentially instantly fatal, and certainly eventually fatal experiments  probably close to the top of the list. Made worse when they call the   Subject   and Fridge Logic sets in with "Wait, what happened to   Even then one of the drama CDs suggests an opening for redemption with   in one of the most subtle crossings of the Moral Event Horizon ever.
 * The Twelve Kingdoms has more than one person, specially the sen-nin or immortals, cross a few of these:
 * King Chuutatsu: Being cynical and upholding the rules didn't make him evil. There WAS lots of corruption in Hou, after all, and as a former government officer he knew that well.  THAT is what made him an asshole.
 * Queen Kekai: Her and Chuutatsu's daughter had a nice little friend, so sweet and elegant! And wait, was she better at everything than the Princess? How dared she!  THAT would teach them!
 * Governor Atsuyu: He had a subordinate named Kouya, who also was the master of a certain demon. But when  and was then horrified at what he had done... what did Atsuyu do?   Eeeeh...
 * Riyo: At some point, she took a girl from Hourai who couldn't speak the language and was completely lost...  "Punishing her for her sins", indeed.
 * Shokou: He admitted he was in For the Evulz, and as such he oppressed the place he was in charge of as Governor. And not only he  and , but he also  . What the....
 * The King of Kou: Okay, this one was insecure about the taika-led kingdoms like En, and then two taika girls with potential to become the Queen of Kei arrived. What did he do? . No, just no.
 * Soul Eater: While she had committed some other terrible acts before this point, Medusa's Moral Event Horizon is generally cited as when she claimed that Crona, who she had been abusing and experimenting on for her plan to resurrect an Eldritch Abomination, is really her child. It Got Worse. Also, Giriko jumped over the line when he tried to rape Maka, when she's at her lowest point; previously, he was just another of the ineffectual minor villains.
 * Despite his could have been seen as redeemable, especially since it was strongly hinted that   However after he , it was pretty clear that
 * Kyubey, the Weasel Mascot from Puella Magi Madoka Magica, has many candidates for that moment. Take your pick!
 * In episode 6, he reveals a very important bit of information about the 'being a Puella Magi' gig, that he had been keeping to himself all that time. That bit of info being,.
 * In episode 7, he manipulates Sayaka's soul gem so that she feels excruciating physical pain.
 * In episode 8, he mocks Homura's attempts of
 * He outright states, at the end of episode 8, that the fate of a Puella Magi is, ultimately, . He shows no remorse for sending young girls to this fate. Then he reveals in episode 9 that.
 * He gives Kyoko false hopes by not giving clear answers to her question about, which results in . He later on recognizes that he did this on purpose, so that Homura had to either risk fighting the upcoming Walpurgisnacht alone, or letting Madoka become a Puella Magi, thus pretty much letting him press the "I WIN" button.
 * In episode 10 but does Kyubey care? Nope. There's a reason that Danbooru (site ads NSFW) has an entire image pool called "Everybody hates Kyubey."
 * And then, in episode 12,
 * And in the tie-in manga Puella Magi Kazumi Magica, it turns out that
 * And just to twist the knife, Kazumi Magica
 * For all of Kyuubey's crossings, in Oriko Magica  also have their MEH moments. The two worse are:   and
 * Though to be fair...
 * However, was absolutely unnecessary at that point, given that   She did it likely out of spite at   for ruining her plans.
 * Deconstructed in Kore wa Zombie Desu ka? by, who makes it his goal to
 * In Muhyo and Roji's Bureau of Supernatural Investigation, the final revelation that puts Teeki over the Moral Event Horizon is the revelation that he . To a lesser extent, his responsibility for also applies.
 * The Mobile Suit Gundam series has TONS of them:
 * In Mobile Suit Gundam, Degwin Zabi compares his older son Ghiren to Adolf Hitler and takes it as a compliment. In return, Ghiren fires a massive colony-based laser at his dad when he attempts to broker for peace. His sister, Kycillia, returns the favor by shooting him in the head.
 * Ginias Saharin of Mobile Suit Gundam: The 08th MS Team has his MEH when he kills his commanders after realizing leaving Earth means ending the Apsalus Project.
 * Also Captain Isan Ryer. One of many who think Zeon are monsters, when Aina Saharin asks for a brief cease fire to get wounded soldiers out of the battlefield, he gives it... then has a GM Sniper set up and destroy the Zanzibar transport they were on! He demands that the deserted Shiro be executed on the spot and gloats to Kojima that he'd never be able to move up in the ranks and be always out in the field.
 * Anaval Gato of Mobile Suit Gundam 0083: Stardust Memory has his when he fires the GP-02A's Atomic Bazooka.
 * The Titans of Mobile Suit Zeta Gundam doesn't show their MEH on-screen, but it's just as horrendous: the 30 Bunch Incident, where they pump a colony full of poisonous G3 gas just to quell a riot. The Federation joins suit when they refuse to indict them, leading to the formation of the AEUG.
 * Haman Karn of Mobile Suit Gundam ZZ reaches hers when she drops a colony on Dublin, Ireland.
 * Which also was the MEH crossing for the person in charge of it: . And for Rakan Dakaran, who openly participated in that one and then.
 * Char Aznable reaches his in Chars Counterattack by dropping Fifth Luna on Tibet.
 * He didn't reach it until CCA? A vocal number of fans think he reached it within the first ten episodes of "Mobile Suit Gundam" when he stabbed Garma in the back after years of leading him on to believe they were best friends. What he did to Kycillia later in the series wasn't exactly classy either.
 * Char also crossed it by cruelly manipulating his teenaged subordinates Quess Paraya and Gyunei Guss's feelings for his own purposes in CCA. So Quess has a crush on Char while Gyunei has one on Quess? Char gives the emotionally/mentally unstable and thus easy to manipulate Quess false hopes about her being the only woman he loves and cares for (despite his own feelings for Lalah Sune and his current relationship with his subordinate/lover Nanai), then behind Quess's back he tells the recently pumped-up Gyunei that he should take Quess off his hands and have a shot at her after the next battle—without any regards to their own mental/emotional states. (And lest we forget: Gyunei was an Artificial Newtype raised by Char after a Colony Drop, and Quess had just become one via having her own borner Newtype talents artificially enhanced, with all the horrifying health and mental problems implied). It works as well as it's expected.
 * Gyunei himself isn't a saint, either, and he ends up crossing the MEH as well. At some point he defeats and captures Amuro's wingman and the local Action Girl Kayra Su, forcibly pulling her outta her cockpit and keeping her hostage in his Jagd Doga's hand. He then stages a Hostage Situation to try getting Amuro and the Nu Gundam to surrender; when the funnels of the Nu accidentally react to Amuro's anger over it, Gyunei uses the Doga's hand to crush Kayra to death, then tosses her lifeless body aside like it's nothing. Amuro, understandably, is fucking PISSED at that.
 * have theirs in Mobile Fighter G Gundam when they attempt to capture the Devil Gundam for their own uses. When the end result of all of this leads to, the second in the list ends up having a Heel Realization and,
 * The Frost Brothers of After War Gundam X probably reach theirs after killing off a group of people in an attempt to awaken their Newtype abilities. When they do with one person, they kill him as well out of sheer jealousy.
 * Mobile Suit Gundam SEED has PLENTY here. Yzak Joule after he kills a shuttle full of civilians, Captain Sutherland and the Earth Alliance in general by nuking their base with a lot of their allies in it, ZAFT soldiers killing POWs after said incident, Muruta Azrael after convincing the EA to fit N-Jammer Cancelers onto their nuclear missiles and promptly launching them into every hole within the meteor base Boaz... Patrick Zala's is kinda hard to pin down, though there are three good candidates - killing off the Moderates within ZAFT (including Lacus Clyne's father) because of JOSH-A's failure, shooting and having his son Athrun arrested soon after or attempting to fire GENESIS on the Earth.
 * Continued on Mobile Suit Gundam SEED Destiny. Lord Djibril sends the Destroy Gundam to attack European cities because they won't follow Blue Cosmos. Then comes his plan on using Requiem on PLANT colonies.
 * And we may have a winner here with Ali Al-Saachez from Mobile Suit Gundam 00. he starts of by recruiting Kurdish kids to become jihadist fighters. The only requirement for joining is that they murder their parents first. Then he send several of them out into the world to do suicide bombings. And when things go sour, he just packs up and leaves them to be crushed by the enemy mobile suits. The fact that he did not give a damn about the cause is just icing on the cake, so to speak. And this is all before the story even started, where he gets many, many more opportunities to show what a dick he really is.
 * Not too far behind Ali we find the A-laws, who have no trouble at all with firing their orbital Wave Motion Gun at a solar elevator, to kill the rebelling forces inside, the 60.000 civillian witnesses, and the hundreds of thousands of people living below who will be crushed by the falling debris, just to prevent the populace from learning of their previous misdeeds.
 * Also, he may have crossed it again in the light novels, if you believe that
 * Nena Trinity doesn't mess around with crossing the line as well. Out of boredom and hatred to those not playing by Trinity's rules, she vaporized an entire wedding in Spain (Louise Halevy was the only known survivor). With her Lack of Empathy and having zero regret over this incident, it's clear Nena's not going to be redeemed or forgiven for this any time soon.
 * Not to be left out, Gundam AGE has Desil Galette crossing the line in episode 14: All this from a 7-year-old child. These events lead to most of the fandom screaming for his blood.
 * Would you believe that AGE is the first Gundam series to have its main protagonist (Flit Asuno) cross the line?
 * The Third Generation wastes no time by making Zeheart Galette go over the horizon in Episode 30.
 * Liang Qi from Canaan has plenty of these, indeed. The better candidates are her repeated abuse of both her Love Martyr Cummings and cute little Yunyun, ... and specially , and then
 * Chapter 239 of Fairy Tail: it was rather obvious from the very beginning that Ultear was evil, but she really clinched it in this chapter by
 * Raven Tail cheap shots, then one member threatens to harm a six year old.
 * Sabertooth's master Gemma, kicks out
 * Minerva, after fighting Erza and Kagura for a while, reveals that she's taken their mutual friend Millianna hostage in order to force them to fight each other. After Kagura is essentially defeated, and prepares to surrender to Erza, Minerva stabs Kagura from behind to claim the points for herself, and reveals that she tortured Millianna while she was waiting.
 * Invel Yura of the Spriggan 12 crosses it
 * Inverted by Haruhi Suzumiya in the second light novel, when she and Tsuruya spike Mikuru's drink merely for the sake of realism during the shoot for her Z-grade movie, despite all the risks it could bring to Mikuru's health. Of course, when Kyon realizes Haruhi's reason for doing it, it's a Berserk Button and nearly earns her a punch in the face... which subsequently leads to her Heel Realization when she realizes that she's doing it wrong (especially in the anime, where we have her staring away from Kyon in remorse and with tears in her eyes) and then to Character Development on her part for the better. As for Tsuruya herself, she only subverts this by virtue of being clueless about Haruhi's intentions, as she agreed to help Haruhi put tequila in Mikuru's drink under the assumption that Haruhi wants to improve Mikuru's acting.
 * The two most evil Anti-SOS Brigade members seriously cross it in the two-part "Surprise Of Haruhi Suzumiya". Kuyo crosses it either in Vol. 1 when she or in Vol. 2 when she  (she might have even crossed it by ), and Fujiwara, up until this point presnting himself as a Well-Intentioned Extremist, becomes a batshit-insane Knight Templar with.
 * Kuyo may subvert this with her Blue and Orange Morality. She (and the entity behind her) is simply so alien in personality that she makes Nagato look like a normal human being. If anyone in the SOS Brigade has crossed it for sure, it's Fujiwara.
 * Averted by Pino in Gunslinger Girl. Right when he's about to kill Aurora for walking in on his plans one too many times, Played straight, however, by Ski Mask Guy in chapter 83 just for being the only one present besides Jose when Henrietta's bad memories of her family's death return because of him and Jose's the only one left alive present.  Dante himself is well beyond the MEH by the time he offed  with a single car bomb, and it's also implied due to Ski Mask Guy's presence at the Battle of Turin that Dante was also behind . He's blackened his heart so much, he doesn't even qualify for Complete Monster status. His last evil act?
 * One of the main villains of Sonic X's third season is a Metarex commander named Black Narcissus, who is so fascinated by Sonic's speed and strength that he wants to learn their secrets, and to do just that, he sets up two Metarex prototypes, Silver and Gold, to test him. And as a special treat, he even knocks out Chris Thorndyke, then captures and tortures him and Cosmo to use them as bait to lure Sonic to him in order to execute his plan to test him. The fact that he did such crap to Cosmo and Chris (who may be The Scrappy, but still doesn't deserve that) leads to Sonic's Unstoppable Rage and triggers his transformation into his Super-Powered Evil Side. It's a good thing Dr. Eggman and his followers came to help calm things down - not only does Eggman convince Sonic to cease his anger, he even admits that he can't stand torturing people when he says to him, "It's one thing to take them prisoner and threaten them but when you actually hurt somebody, that's going too far." Damn... when the Big Bad denounces your tactics to the protagonist, you know you've crossed the MEH.
 * in Kämpfer is implied in episodes 10 and 11 to
 * Allegedly crossed by the high school basketball team captain by propositioning a minor, which sets the plot of Ro-Kyu-Bu! in motion as the entire team gets punished for his alleged crime (which hasn't been proven as of the current episode), forcing the main character to coach a girls' basketball team consisting of grade-schoolers in an example of misplaced Laser-Guided Karma at work.
 * from Air Gear proved himself an as asshole when he.
 * It Gets Worse:
 * Peach Girl: Kairi has a trio of obsessive clingy jealous girls who once attacked Momo and threatened to set her on fire if she continued taking up Kairi's attention.
 * In Honoo no Alpen Rose, Count Germont is a complete Jerkass and Stalker with a Crush to Jeudi. He truly clinches it when
 * Ren Sohma from Fruits Basket actually crossed this before the story took place, by  The factors that make this even worse than  's constant puppy punting (which include many acts that qualify as borderline MEH crossing themselves) are: the extremely petty reasoning behind it   as and how   In few, Ren's horribly selfish and cruel action was actually the reason behind, like,   Mind you,   is NOT an angel, and yet in perspective   comes off as a lesser evil since it's Ren who

 * Kenichi: The Mightiest Disciple: While none of the YAMI masters are good guys to begin with (Affably Evil, at best), resident Pencak Silat master Silcardo Jenazad is a very special case of bastard. In order to get a replacement for his slain disciple (who he'd killed himself via avalanche several arcs earlier for basically disrespecting their martial art), he . And then after that happens.
 * And just in case you don't think the above moment is despicable enough for him to have crossed the horizon, what he does in subsequent chapters should be concrete enough evidence that he's beyond any chance of forgiveness:.
 * In Umineko no Naku Koro ni Rosa Ushiromiya either seriously kicks the puppy or downright crosses this when she . Though it seemed minor at first, you would recall that she gave Maria the stuffed lion in the first place, and that Maria considered (or made) him real, and that he was probably her only friend. She also "kills" one of the Siesta sisters, though inadvertently when she threw her on the ground. And often at times where she slaps Maria. Yes, you should show your child discipline, but when you take it too far, it is just abuse. And she often claims to have to go to work, but in reality, she goes to spend the night with one of her boyfriends—leaving she would often leave Maria home alone, often to the point where she would have to go out and get her own food. She even left one boyfriend when he told her to spend her time with her daughter. But what ultimately made her cross the horizon would have to be when she told Maria that she never loved her and wished for her to have died, so that she would have a happy life. She even tells her to go to Hell. Though, given her status as a Tragic Villain, a victim of abuse and bullying from her own siblings and her father (which Rudolf actually aknowledges), the local Chew Toy, or most likely just stressed at work, she might subvert this trope. Though, you wouldn't forget that Beatrice was disgusted by her behavior.
 * She actually does, because Rosa is the very strange case of an abusive mother doubling as Mama Bear. In EP-2, she faces the goat servants on her own to protect herself and Maria, taking them with pens to the eyes and shotguns; in Episode 8 of the game, she shoves a rifle down 's throat when she mocks Maria and tells her that her mom will abandon her. Not to mention, several of the episodes described here happen in different timelines (and the one described at the end happens only in EP-4), thus how abusive or nurturing she is can seriously vary depending on which EP we're talking of.
 * Eva-Beatrice crosses this when she repeatedly murders both Rosa and Maria, purely for her own amusement, and in very creatively cruel ways. She really crossed it when she was supposed to murder a person once in the Twilight. She actually gets so bad that, again, Beatrice is squicked out and disagrees with her.
 * But, now it's time to talk about the Big Bad herself, Beatrice. In one of the episodes, she feeds Rosa the body parts of her siblings, and forcefully tries to have her eat her own daughter's head! Now since Maria is supposed to be her Morality Pet, this comes as just as jarring. Not to mention that she also got a salad out of Eva's tongues by repeatedly ressurecting her, and then cutting out her tongue, and that she lied to Battler that she saying that she turned good, and that she probably planned on creating Eva-Beatrice, and the effects that it would have, because she knew that Battler would try to help her, and that he would've signed a contract with her if Ange had not intervened. And in another episode, when Battler became her furniture, she strips him naked and makes him wear a collar, and then gives him "The Reason You Suck" Speech, and then has the goat butlers maul him to death. Though, like Rosa, she might have a Freudian Excuse, or just avoids this list by her Pet the Dog moments with Maria.
 * ... And as mentioned above, it heavily depends on which EP we're talking about. The deal with Rosa and the "dinner" is from EP2, while the majority of the Pet the Dog moments with Maria happen in posterior EP's.
 * Bernkastel does truly horrible things, but in EP7, she shows Lion Ushiromiya the miracle of his/her existence, and then proceeds to force Lion and Ange to watch a horrible scenario in which Ange's parents are the murderers. Ange is unable to handle this, and as such she is once again torn to pieces. When Lion tries to give Bernkastel a What the Hell, Hero? speech, Bernkastel shows Lion his/her eventual fate- being massacred along with the rest of the family on October 4 and 5, just like in all the other universes. Bernkastel laughs at Lion's fate, and she is unwilling to let Lion escape.
 * Kinzo also crossed it when it was revealed that Yasu, aka the real persona of Beatrice, Shannon and Kanon is actually his child fathered on his own daughter Beatrice, who he kept isolated and eventually raped because she resembled her mother, Kinzo's deceased mistress. Can you say "Just like Noah Cross"? Good.
 * Let's not forget the main villain of Inuyasha, Naraku. It could easily be said that Naraku never crossed the MEH, because he never was out of it to begin with. In fact, his very first act was to It's not shown what he does between this and 50 years until the series starts, but it can't have been pretty.
 * Not to mention, there's what he did to Kohaku and Sango. More exactly, . Made worse when
 * He ain't the only one, either. Shiori's grandfather crosses it to a horrifying degree twice: first, when, and second when
 * Mykage, the Big Bad of Aquarion Evol, crossed the line big time when he . Or, alternatively, he crossed it for.
 * Sailor Moon has a few Moral Event Horizon crossings. In the first season, for example, Queen Beryl crosses it by killing Zoicite, showing absolutely no remorse nor shred of willingness to relent despite Kunzite's attempt to take the blame for Zoicite's loose-cannon attempt on Tuxedo Mask's life.
 * In the second season, Rubeus crossed it via his extremely cruel and abusive treatment of Cooan, the member from the Quirky Miniboss Squad who loves him, in which he first mocks her over losing to the Sailor Senshi, then gives her an explosive MacGuffin and orders her to practically kill herself for him. The poor girl goes into a full-blown Villainous Breakdown at that, and only Rei's compassion and efforts keep her from commiting suicide. And for worse, after Cooan and Bertier have their Heel Face Turns, he goes even further than that by getting their eldest sister Petz Brainwashed and Crazy with another MacGuffin, and then leaving her and the remaining sister Kadaveras to die when the MacGuffin overloads.
 * Wiseman crosses this when he corrupts the well-meaning yet extreme goals of the Black Moon people and their leader Diamando. Unlike Rubeus, Saphir eventually got wise to Wiseman's act, but Wiseman kills him just as he's about to show Dirmando the light as well. Dirmando is not amused. And then it's clinched when he kidnaps Chibi-Usa when in a particularly low point, then giving her Fake Memories and forcibly infusing her with black energy, which turns her into Black Lady.
 * In the third season, Telulu crosses it with how she deals with Mimet. To put it in perspective, Sailor Moon herself is horrified to see one of her nemesis being dealt with in such a callous fashion. Damn... when a hero is mortified by the death of a villain (who could've killed the good guys, including him/her, with a single blow, mind you) at the hands of another villain, you know the killer in question has crossed a line.
