Part of believing that in the resurrection and redemption by Christ and believing in an all-powerful God is that no man is so far gone that he is beyond the grace of God to save. I think many of us will be very surprised who we find in heaven, and who we do not find.
Anyone can be saved but not if you havent admitted your sins. You don't just automatically get forgiven after death. I doubt Bin Laden was asking for forgiveness during our raid into his house.
