A man went into a bar in a high rise. He saw another man take a pill, take a drink, walk to the window and jump out. He flew around for a minute and zipped back into the bar.
As the amazed newcomer watched, the man repeated this twice more. Finally the man asked if he could have a pill. The flier said it was his last one. The man offered five hundred dollars to no avail, so he made a final offer of a thousand dollars. The man said that it was all he had on him.
The flier reluctantly gave in, took the cash, surrendered the pill, and turned back to the bar. The man took the pill, took a drink, went to the window, and jumped out only to fall to his death. The bartender walked over to the flier at the bar and, wiping a glass, said, "You sure are mean when you're drunk, Superman."
I have lots of ideas for what you could do, but that's because I'm that kind of person. For your family though, brother, you did the right thing. With how screwed up our laws are, if you do or did a single thing to him, that asshat could have/would have either had you arrested or sued you. I know that sucks to hear, because it bugs me just to say it. But, your wonderful family needs YOU more than you need revenge on some piece of shit that isn't even worth it.
Go spend some time taking it out on a punching bag.
Talk to your buddy and make sure that piece of shit is never part of your life again.
Put a cigar out on his eyeball while a couple of friends hold him down.
If you're into martial arts, get on the mat with somebody and go at it for a while.
Wait... not the third one.
