I agree with Brian's comments. As much as I woudl haev problems with anyone accused of having questionable ethics, I would never wish on anyone to go through what he must have experienced while being stabbed.

Sometimes karma does adjust, but perhaps (for those who believe in reincarnation) he'd simply gained all of the lessons and insights he needed to have in the current life, and dying this way was part of that experience. (Sorry if I'm getting too "new age" for people here...)
