Yeah, I think if you go to his side you are definitely getting in God's way. I'd let him sit alone for a LONG time to think about his life & choices. Of course, if the laws there are anything like the U.S., he'll be in jail for quite some time. Plenty of time to think there.
Before you see him again, why don't you run by the hospital to visit the victims and their families? That should give you some much needed perspective.
