It probably wasn't very fun for the man who was originally killed by AK47 fire, or his friends.
Who is the bad guy here? Well, everyone I know who has been anywhere near a war came away worse. I don't think war turns you into a good person, whether you're firing automatic weapons at sleeping men, blasting a hilltop trying to kill someone's son, or sleeping with a machete in a town where the rule of law has collapsed.
