Guilt, Anger & Feeling Sad

I HATE that I am mad at my brother right now, because he is dying and probably only has a couple more days to live.  I feel guilty for it, but he has been so mean to my parents and rude to everyone that I just want to shake him.  I Love him but at the same time I just want it to all be over with so my family can move on.  I know this most likely makes me a bad person, but I can't help the way I feel.  I want him to just stop suffering and making everyone else suffer to.
