Dear Carrie,
Your brother sounds like a very selfish person. But I want to know what causes him to act this way. Since he seems to be doing this on purpose, maybe the only way to do with the problem is to try to find the cause.
I think your brother is probably hurting in some way. Perhaps he feels unsafe because he is not a full part of the family. He could be jealous (嫉妒) of your mother's love for the rest of you over him.
It is wrong to fight anger with anger though you think it is a need to help your mother. I suggest you try to help your brother by treating him with more care and love. It must be hard for him to grow up in a family where his sisters had their real mother but he didn't. Try to let him know that you care about him. Over time he may come to know how lucky he is and start to treat you all with the same kindness that you give him.
