If Arafat were standing in front of me, I'd shoot him in his face.
If I happenned to hit someone who was standing beside him, I'd keep shooting til I killed Arafat.
Sometimes ya gotta do what accomplishes the "greater good".
Say for example you could have killed Hitler, but in doing so, you'd have to kill a couple hundred innocent people, but you'd save 12 million lives...what would YOU do?
