I think my brother is trying to make me hate my parents as much as he does.
Your brother sounds cruel. Why does he hate your parents so much?
I'm not sure, but he treats them very badly.
In these situations it's good to talk with your family about what's going on. I think you should ask your brother why he feels the need to treat your parents badly, and ask him to treat them better.
I think he feels mistreated and wants our parents to feel the same way.
If your brother is feeling mistreated, then it's important to discuss this with him and your parents. They may not be aware he is feeling this way, and talking about it can help resolve the issue. That way, your family can get along and be happy!
