What I figure is everyone was driven insane by the hollowing. Hence the reason everyone is always laughing. So when people like the btuchers went undead and eventually hollow they too went insane. Only to retain fragments of their past lives. Such as how the butcher continues to cut meat. Then when the hallowed crazy people run into others the just want to murder them on site. The only few that seemed for the most part to retain some of their sanity are the NPCs you end up talking too and most of their sanity is highly suspect. Hell that onion dude outside of Sen's Fortrace is really crazy when you talk to him. I bet he's like on the verge of fully crossing over.
