History MoralEventHorizon / CriminalCase

* Dr. Shweta Noorani crosses it when she is revealed to have been behind not only the Protozane trials that resulted in the deaths of several kidnapped people, but also masterminding Rosie Summers' murder of Wendy Stokes by drugging the former with Protozane.
* Dreamlife lab scientist Emilio Fuller starts off as being one of the few [[OnlySaneMan sane men]] in the organization, but he crosses it at the end of Misty Grove. He discovers that his estranged father, Tony Marconi, is doing all of Rozetta's dirty work to protect Emilio. Unfortunately for Tony, Emilio sees him as nothing more than a criminal and genuinely believes that Dreamlife was making the world better. When Tony finally manages to meet Emilio, Emilio pretends to help him destroy the Protozane shipment with a molotov cocktail, only to use it to [[{{Patricide}} kill Tony instead]]. Emilio shows a disturbing lack of remorse, even blaming Tony for stepping in the way of science, leading to him getting a life sentence.
* Toby Hansen commits one of the most brutal murders for an opening district case, savagely bisecting a freshman for a petty reason: the victim was starring in his student film and was subject to transfer elsewhere. Angered with the possibility of having to reshoot, he dressed up as the film's villain and killed her by chainsaw which he puts on film, effectively creating a SnuffFilm. Toby boasts that his visionary approach to film will be eternally remembered, showing eerie pride in his "art." Naturally, he acquires a hefty sentence for his "trouble".
* The University had a minor character, Gunnar Burns, commit one of the most gruesome murders in the series in Case 40. Even when he first appears, he's not a very nice person and doesn't even try to hide it. He even murdered his ex-wife as revenge for her divorcing him 20 years ago, and kept that secret for two decades until he learns his backyard is going to be dug up by the government, forcing him to try and hide her remains in Grimsborough University's tennis court. He is caught by star athlete Stephanie Griff, and his response to that is to knock her out and torture her with a vice, slowly crushing her head with it. Not only is he completely disrespectful to everyone around him (including the police force), he doesn't feel remotely bad about anything he's done, instead blaming it on another person or something else he didn't like. This is enough for Judge Powell to sentence him to life in prison without any possibility of parole.
* Polly O'Brien initially appears as an endearing, friendly girl when she first appears. Later, however, she, alongside all four other current Ad Astra members, kidnaps and whips Professor Kevin Charles to death on Rozetta Pierre's order. Polly instantly drops her innocent facade, proudly condoning her acts and the attention it brings her, and showing a disturbing LackOfEmpathy to both Charles and her deceased boyfriend (who died in the previous case), all within the span of what is canonically around 12 hours in game.

* Ad Astra, the villainous organization that the Grimsborough PD investigates after shutting Dreamlife down, also manages to do a lot of damage during the later half of the season. All five of their student members kill Professor Kevin Charles by taking turns whipping him to death, ordered by Rozetta because she thought he would expose the identities of the original members. In Spring Fields, one of the members, Fornax, a.k.a. Julia Brine, puts the region in a crisis by burning down all the cornfields with the intention of replacing it with her own GMO corn, laced with mind-controlling Protozane. Although she is arrested for conspiracy, three more members continue to plot against the Grimsborough PD. One of them is Christian Bateman, one of the most mentally unstable killers in the game, who gets released from prison out of the blue and gleefully talks about how he's going to carry out "Plan Supernova", a city-wide blackout, to throw the city into chaos. Soon afterwards, a hit is ordered on the player character, which ends up killing rookie cop Mia Loukas instead. The hit turns out to be ordered by Mayor Joe Warren, who had been nothing but friendly to the player before. After averting Plan Supernova, Louis Leroux, a journalist who had helped the player and Jones find Zoe Kusama, murders Zoe and is discovered to have been not only another member of Ad Astra, but had used his status to conceal the meteorite crash. And to make it worse, Ad Astra are merely decoys for the GreaterScopeVillain of the season, [[YouHaveOutlivedYourUsefulness who has them executed once their plans fail]].

* Morgana Blackhawk, the stoic witch coven leader, kidnaps several children around the Midwest alongside elder mentor Pandora Geiss, with the intention of eating them to increase her power. When her sister Belinda finds out, she blackmails Heather Night into killing her. Morgana's plan is enough to horrify the team and cause them to strip her off her power.

* Dreamlife lab scientist Emilio Fuller starts off as being one of the few [[OnlySaneMan sane men]] in the organization, but he crosses it at the end of Misty Grove. He discovers that his estranged father, Tony Marconi, is doing all of Rozetta's dirty work to protect Emilio. Unfortunately for Tony, Emilio sees him as nothing more than a criminal and genuinely believes that Dreamlife was making the world better. When Tony finally manages to meet Emilio, [[HeelFaceMole Emilio pretends to help him destroy the Protozane shipment with a molotov cocktail, only to use it to]] [[{{Patricide}} kill Tony instead]]. Emilio shows a disturbing lack of remorse, even blaming Tony for stepping in the way of science, leading to him getting a life sentence.

Just about any murder that wasn't [[AccidentalMurder an accident]] or whose perpetrator [[SympatheticMurderer wasn't sympathetic]] would qualify for this, but several individuals in this game deserve special mention. Due to the nature of the page, '''Unmarked Spoilers''' are inevitable. You are warned.

-->Polly: I see you fell for my innocent act, (Player). Just be careful not to underestimate me. Look what happened to my boyfriend. He annoyed me...and oops, now he's dead.

--> Haruki: "There is something of far more importance at play than the trivial notion of a 'best friend', and Marcus should have understood this!"

* S.A.R.A. head Denise Daniels, initially a morally gray character, is later revealed to be [[TheManBehindTheMan the real leader of Ad Astra]] as well as Rozetta's mother. Interested in creating a species of super-resilient humans, Denise created Rozetta as an attempt, only to disown her when she discovered Rozetta was merely smarter than most people. Upon the meteorite hitting Grimsborough, she uses Rozetta to extract the Berzelium, secretly helping Denise grow nigh-invulnerable neo-humans behind Ad Astra's back. Once Ad Astra is crippled by the Grimsborough PD, Denise resorts to having them killed one by one and attempts to destroy Grimsborough with a nuclear earthquake, in which she and her neo-humans can rule over Grimsborough. Fortunately, the team manages to avert the earthquake, but Denise sics her neo-humans into Grimsborough, only for her to be killed by them after proving herself to be inferior to them. Overall, Denise turns out to be one of the most despicable villains in the game, even topping the likes of Albert Tesla and SOMBRA.

** He crosses this again when he kills Karen Knight for refusing to support their master Albert Tesla's plan to destroy Pacific Bay, implying his willingness to let innocent lives killed just to appease a madman's goal of creating a virtual reality. Luckily, his KarmaHoudiniWarranty runs out right after this, as Frank Knight shoots him dead.

* Milton Grimmes is the head of the Crimson Order, an organization that is implied to be behind almost all of Grimsborough's murders, including the murders of Rachel Priest and Adam Bentley. Then, he tries to kill the player character, which would've let crime go unpunished in Grimsborough.
