I feel joy over Osama Bin Ladens death because it means he can no longer harm others. He who takes life, or someones rights unjustly should understand that they don't deserve life or rights themself. Also I feel joy that justice has been done and showed that "no you can not get away with it, you will be hunted down like a dog." Not giving in to terrorist demands is a start, but hunting them down will show them it is not even worth a shot.
