If God knows that you are going to kill someone, it's not your destiny. It's not what you live to do! God knows that you are going to, that doesn't mean that He wants you to. That's free will. If you think fatalistically, then no matter what, if your "supposed" to die on aug 5th 2012 you're going to, even if you stay home all day or rob a bank. If you die because you jump a cliff, it was free will to jump the cliff, God didn't push you off! If you get kidnapped and the nappers have ak's, with a fatalistic worldview, you immediately assumed,"I am going to die before this is over", then you accept it without any fight. You assume there is no need to pray for protection, and if the nappers drop the guns, you don't grab them because... you were "supposed to die..." So then you get shot, cause they dropped the guns and you didn't go for em. And good thing God is forgiving anf loving, because when you died after not going for the gun, if I was God (which I'm not anywhere close) I woulda slapped you for not going for the gun and throwing it out the window!
