I'm sorry, but to me... Alois from Black Butler and Alex from A Clockwork Orange are like the same: they like to do violent stuff and treat it like a little game.
Now before you Alois fangirls go like "OMG why would you compare my sweet Alois to a rapist?!?!?", Here's my reason. You see for both of them, we don't know that their violent and insane because of the environment they grew up in, or if they are just born evil. Well, for Alois, we do see that he was kidnapped as an infant to some village, so maybe the experience in the village must have change his psyche. But even as a child, he was still violent, like wishing death upon everyone.
But all I can say is that they are like the same to me. Alright! GOOD NIGHT!!
