I don't know anything about Salman Sharif other than that he ran a violent resistance group that planned and executed a nearly-successful assassination of a prominent politician. Doesn't sound like a very nice guy, does he? Well his target in 1996 was Uday Hussein.
It was obviously against the law of his country for Sharif to attempt to kill Uday, but I have a rather hard time condemning his actions; Uday was responsible for thousands of deaths in the past, and would certainly be responsible for thousands more in the future. Uday hadn't broken any laws -- his word was the law -- nevertheless, I believe that an attempt to kill him was morally justified. It wasn't attempted murder, it was attempted justice.
Someone please help me make a distinction between Salman Sharif, and Paul Hill. I want to be able to, but I'm having trouble. Yes, it sounds like Paul Hill was a little crazy, but let's isolate his intent from his motive. He may have been motivated by "God telling him what to do", but his intent was to kill people responsible for murdering babies, so that they couldn't murder any more.
[Note: even if you're pro-choice, consider how you could draw a distinction without resting on your belief that an unborn baby is not a human.]
