Brother has had sexual contact with sisters - what now?

Re: Brother has had sexual contact with sisters - what now?

Befriending him is my intention, but he’s making it harder for me. We haven’t spoken for days, and just today he made me yell at him for trying to order his sisters around again, and not listening to his mother when he should have.

I have to let him know that his family will “not” despise him, PROVIDED that he changes himself. The two younger ones had no respect for him (rightly so), but I told them, that if he ever changes and no longer seems like a threat, it’s okay to consider his actions and efforts in good will. Not happening anytime soon though. Heading to a psychiatrist seems to be when I’ll initiate conversation with him.

More importantly, I have to somehow ensure my father will change his attitude when I’m gone to university again. Kicking him out of the house for a few hours when he’s displeased isn’t right. It completely ignores the problem.
