That's part of the problem. They are training those guys to kill. Then they send them over there where they get that emotionless killer mentality. Then they bring them back and cut them loose without reprogramming them. That's why the suicide rate among returning soldiers is so damn high.
I am speaking of the life of a man who knows that the world is not given by his fathers, but borrowed from his children; who has undertaken to cherish it and do it no damage, not because he is duty-bound, but because he loves the world and loves his children… - Wendell Berry, 1971
