Thank you, I finally did sleep.

I know someone who reminds me of your description of your brother. The person I have in mind has done nothing but self-destruct, hurt others, and makes everyone who tries to get close to him miserable. Again and again he's blown good opportunities that were offered to him with his meanness and lack of respect for anyone. He's a terribly abusive, non-productive person who just hurts everyone.

I fully believe that in some cases there are people who would be better off not in this world because sadly, they have spread hatred like a plague and only hurt good, decent people.
