The diffrence bettween Carlo and ''Them''

There is one thing that I find confusing about a family. I had said before that no one should have rights over other people. But Maria just told me that their parents have rights over them. Well they said its more of a duty, because, they must care for you. Like give you food and clothes, and teach you things that you don't know. So that one day when you won't have them any more, you can manage for yourselves.(When your grown up.)
Kind of what like Johannes did and was to me...
But having  right over other people is using force. Its shameful.
I must talk about Carlo. This last few days he has been trying to wheedle himself, into my books. I think he's trying to warm up to me. He has been trying real hard to convince me, that he was good. I don't like Carlo for one thing he is good at deception. Good thing the guards in the camp would do that often. Because I know how to deal with it. I speak to Carlo only when i have to. But i will always do it politely. Just like I did with ''Them''.
Carlo is JUST like ''them'' he is stupid. I don't mean the kind of stupid the children are like. But stupid as the guards in the camp. He already know that I will not let myself be impressed by him and he also knows that I will expect anymore of him. The thing that make me uncomfortable around Carlo is the he is so good at deception that Maria and the two little boys did not know that Carlo is evil, and so did their parents. They just think he is an ordinary boy. And that is why I am uncomfortable in his presence...
