Moral Event Horizon / Visual Novels

  • Ace Attorney:
    • Manfred Von Karma killed Edgeworth's father because he tarnished his perfect record, adopted Edgeworth, trained him to be a prosecutor, then set him up to be convicted of murder. He was the prosecutor who was trying to prove him guilty.
    • While we all knew Dahlia was a Bitch in Sheep's Clothing from the moment she popped up, her status as a monster isn't fully confirmed until the flashback case where she convinces Terry Fawles (implied to be mentally disabled) to kill himself because he doubted that she loved him. This is after framing him for murdering her and later her step-sister, and this is just as he's about to give testimony that might exonerate himself and convict her.
    • Matt Engarde crosses this long before he actually commits a murder, when he, after essentially throwing away Celeste, who loved him, causes her new fiancé, his rival Juan Corrida, to break up with her by revealing that she was once his girlfriend, leading her to be Driven to Suicide. Juan's role in said event could be considered his own Moral Event Horizon crossing as well.
    • The Walking Spoiler villain of Dual Destinies, the phantom, has done so many things that we don't know of that it's hard to say when exactly they crossed it. But during the events of the game, it's either killing a police officer and impersonating him for over a year so he could corrupt the justice system, sabotaging two rockets and killing two people, then trying to pin it on the daughter of one of the victims, or bombing a courtroom and trying to kill everyone in it just to get rid of one quite far-fetched piece of evidence. And they don't regret any of it.
    • Quercus Alba ordering the death of Cece Yew (which doubled as Manny Coachen's as well since he was the hitman and what allowed him to become an Asshole Victim) in Ace Attorney Investigations and Blaise Debeste, Patricia Roland, and Di-Jun Huang's body double having the real Di-Jun Huang assassinated on a secret trip to visit his orphaned son in the sequel.
    • And then in the most recent game Spirit of Justice we have two examples.
      • Roger Retinz aka: Mr. Reus may seem like your typical killer at first but they cross the MEH when he forces Betty deFamme to commit manslaughter of a long time fan and protege of his just to get Trucy convicted for the murder. Then he runs a smear campaign against the Wright Anything Agency saying they defend criminals and are happy to see convicts and murderers go free, what's more is he forges Trucy's signature on a 5 million dollar contract which allows him "compensation" so he repossesses the entire Agency just to spite Trucy and her friends. The sheer lengths this man will go just to get his revenge on Troupe Gramarye, never mind that Trucy was the White Sheep of the Troupe, are frightening.
      • But then we get to the Big Bad themselves who makes Retinz and almost every other example here under Ace Attorney look like kiddie film villains. Ga'ran not only kills Apollo's biological father, but she is perfectly okay with letting baby Apollo burn alive in the fire. During that fire, she smears the noble Dhurke Sahdmadhi's name and makes the entire public think he killed Amara and causes them to have a severe hatred of defense attorneys. Not only that, but she passes a law that causes every defense attorney who tries to defend a client in the kingdom of Khura'in to get the same sentence that the suspect would have meaning she's sent hundreds of thousands of innocents to the gallows. And then she even murders her own husband and threatens to kill Amara (who it turns out wasn't dead) and Rayfa should Nahyuta not comply with what she's done.
  • Dangan Ronpa:
    • Monokuma takes a flying leap over the horizon and keeps right on going when he kidnaps 15 innocent students, forces them to murder each other in order to escape, and then brutally executes a student when she dares to defy him. The Reveal that said student was the mastermind's sister only makes it worse.
    • In the spinoff game, Absolute Despair Girls, it would be far easier to count the times where Monaca isn't crossing it. To pinpoint the spot where she first crosses it, her complete disregard of Masaru's apparent death.
  • Super Dangan Ronpa 2:
    • Nagito Komaeda crosses the MEH in Chapter 1, when he engineers the first murder, intending for himself to be the victim and kickstart the students' battle against despair.
    • The culprit of Chapter 3, Mikan Tsumiki, crossed it due to the Despair Disease, which made them remember their identity as a member of Ultimate Despair before entering the Neo World Program.
      • In fact, all of the Hope's Peak students on the island (sans Chiaki, who was not a Hope's Peak Academy student) are revealed to have crossed the MEH before the events of the games, when they joined Ultimate Despair to assist Junko Enoshima's plan to spread despair through the world. They were so far beyond the MEH that the Future Foundation placed them into the Neo World Program, which was designed to overwrite their memories of Ultimate Despair. The surviving students almost cross it and the Despair Event Horizon again thanks to AI Junko.
  • New Dangan Ronpa V3
    • Korekiyo crossed the MEH by killing Tenko and Angie so that his sister can have friends in the afterlife. And even if that wasn't enough, there is what he did in his Love Hotel scene.
    • The true masterminds of the game basically crossed the MEH by having 53 previous killing games. If we assume that each killing games has about 15 or 16 characters, then about 800 lives were lost all for the sake of good television.
  • ClockUp's Euphoria:
    • Subverted with Nemu, when it seems like she is the mastermind behind the whole simulation; in reality, it is Evil Genius Kanae who had taken a flying leap over the line during the Betty and Veronica Switch in the True Ending.
    • Keisuke crosses it in the end of the Special Bad Ending where he uses all the girls, except Kanae, who he killed, as depraved Sex Slaves: Rika is forced to act like a dog, Byakuya his "work of art" that he tattooed and he constantly whips, Natsuki is his "lewd cow" whose mind have been fried by a powerful drug, and her pleasure nerves were extended to such a point that she is in a constant state of delirious pleasure, and even a slap makes her feel good, and Nemu serves as a trophy in the wall that Takato occasionally uses. The first three are also pregnant, and is heavily implied that Takato is impregnating them constantly... yes, it's that kind of bad ending.
  • Umineko: When They Cry has The Witches' Tanabata for Bernkatsel. You initially assume that because of her own backstory, she'd be sympathetic to the protagonists. Then you learn in that story that she ruined Ange's life, just so Ange could die later on in front of Battler. Then she mocks you, the player, and says that's just what you wanted to see! At that point, many players wanted to see her get sent back to the "Groundhog Day" Loop... or worse.
    • Screw you, Erika!. The exact moment for most people differs, but if you haven't felt she crossed it before, there's a line she says in the 6th Episode that hurls her across this line:
    Erika: "I dashed all over the mansion, visited all the 'crime' scenes, and...completely severed their heads... All five people I killed......were very much alive and faithfully playing dead until the moment I killed them."
