I can't speak for Psycho Pass, but I can for Berserk. At first glance you'd think Berserk is just that. A violent manga filled with sex, rape and gore just for the heck of it. But it's not. F*****ckkkk it's no where near that.
So I'd say don't let face-value be your judgement for anime/manga games and so on.
It's interesting though, sex, rape, and gore aren't even murder or killing, technically. I think of gothic fantasy as notable for how non-violent it is, the emphasis on characters and stuff like that. Game of Thrones is scary because you actually kind of like those characters, not about the wars etc as much. The pivotal moment in the series is <Spoilers> just plain sex. The most horrifying moment of the Eclipse is forceful sex.
I'm convinced sex is more powerful and destructive than violence, the frequent cause of wars, etc.
Of course you are just talking about trailers vs looking at the whole series etc, I guess I just wanted to talk about Berserk again.
