Ruth Rendell said this quote

“ You make someone into a object of – not so much of pity as of weakness, sickness, stupidity, inefectiveness, do you see what I mean? You hit them for their stupidity and their inability to respond, and when you’ve hurt them, marked them, they’re even more sick and ugly, aren’t they? And they’re afraid and cringing too. Oh, I know this isn’t very pleasant, but you did ask.”“Go on” he said.“So you’ve got a frightened, stupid, even disabled person, silenced, made ugly, and what can you do with someone like that, someone who’s unworthy of being treated well? You treat them badly because that’s what they deserve. One thinks of poor little kids that no one love because they’re dirty, sovered in snot and shit, and always screaming. So you beat them because they’re hateful, they’re low, they’re sub-human. That’s all they’re good for, being hit, being reduced even further. ”
