I hate my brother very much
I am sorry to hear you feel that way. Why do you hate your brother?
Because he is so pathetic. He does everything I tell him, he allows himself to be enslaved
Your brother is your family, it's not right to call him names for no good reason. It's a good thing that he listens to you. it doesn't mean he's slaving himself out.
I can call my brother whatever I like.
It is wrong to call your brother things and have hate for him. The two of you could be very important people to each other if you work on your relationship.
