your victims will probably just let go of their anger instead of turning their grief into ghosts as they still need to live and move on

That's a thought I notice a lot of folks don't usually have; a lot of people are quick to say the survivors will become 'terrorists' (freedom fighters more like), but actually most will try to scrape up what they can of what's left of their lives. I'm reminded of someone I read about who had to literally pick up the unidentifiable pieces of his brother in a blanket after his brother, wife and kids were struck by a drone bomb, and the poor guy returned to his meager life but gained a stutter after the experience.

(But sure, it's the veteran we're supposed to feel sorry for)
