I once wished my brother would die, not to get him out of my life but so that he could stop being tormented by 'his demons'.
This one time was when he was very ill, I got my wish, and I really have very few regrets about it. He would never have been who he wanted to be had he lived, and Joe would never have had the dad he wanted him to be.
It's sad but true, I really believe my brother now has the peace he would never have found again in life. I miss him, but it would be selfish to want him alive as he was.
