My room mate sucks but I need a second opinion?

That was a struggle to read. I'd say if you are really friends with him, he should respect you. I think that he should have at least the decency to be respectful of you since you took him in. I'd say talk with him and if he still refuses to be civil with you and your brother, offer him an option of leaving the house (but give him notice). He's not really a good friend to you at all.
