History NightmareFuel / HighschoolOfTheDead

** Most of the group seem to show little to no issue with actively (re)killing any of "Them" which, while sensible, they come to grips with distubingly fast, hell, one of Takashis' first Zombie kills was ''his best friend'', with very little actual angst afterwards.

** Made worse, considering he tried to manipulate Shizuka into staying with them when Saya decided it was best to split off from Shidou and his students. Given [[IHaveYouNowMyPretty his obvious intentions for her]], had Hirano not held him at gunpoint, Shizuka might've been gang raped.

*** only resident BloodKnight Saeko actually hesitated to kill some child zombies, then turning it around after a weird resolve speech from Takashi that, for some reason, involved him Groping her breast in what looked like a DeathGrip, and she proceeds to bash the kid zombies heads in while proclaiming it turned her on.

** Particularly in the first episode [[spoiler: where Toshimi is torn apart on the stairs, when her so-called "friend" abandoned her to die]]. You see closeups of "them" [[spoiler: biting into her arms and legs]] as "they" drag her further into their midst, 'til all you see is [[spoiler: the lower half of her body writhing in agony along with her pleas... which become anguished sobs, which stops once she starts gurgling on her own blood... and then]]... [[NothingIsScarier Damn]], [[CruelAndUnusualDeath what a way to go.]]

** Some examples can hit home a bit too hard, depending on a person's experiences. For example, if you ever experienced even mild BloodKnight tendencies, then [[spoiler: Saeko Busijima]] is more than enough to scare you if you fear becoming a SociopathicHero even a little.

** Shidou himself is pretty horrifying from the start, but look at his "subjects". The first one we see (the one with the phone) is clearly on the last vestiges of sanity, and the others are essentially little more than wild eyed, slobbering sex slaves. Perhaps the worst part is that they were all once normal highschool students, but thanks to the depravity and megalomania of a single man...

* Any scene that show's Kohta's darker side. He's been so traumatized by years of abuse during high school that he'd not above killing the living people who made his life a living hell.

Of course, being a series about zombies, it was inevitable.

* Just about any scene exposing the [[HumansAreBastards darker nature of humanity]].

* Literally ever single scene involving Shidou's "cult". Shidou himself proved himself a horrifying CompleteMonster from the getgo, but look at his "subjects". The first one we see (the one with the phone) is clearly on the last vestiges of sanity, and the others are essentially little more than wild eyed, slobbering sex slaves.
