You said you fear the words that will come out of his mouth. He should fear the words that come out of yours IMHO. You may have to just make yourself ice when you must deal with him or see him. Short, direct, devoid of emotion, business only. Give him no in, not even to your anger or disgust, as it will give him a foothold to manipulate. Don't listen to a word he says, and if he speaks of anything other than mutual business, walk away.

On another note, I am really sorry for the loss of your brother in such a tragic way. Those wounds don't heal clean.
