Query: disrespectful

I am an ex-serviceman who has been on ops, but I found this book and some of the 5 star groupies shameful. Is this a man who is a killer or a soldier. A soldier serves his country and friends, a killer serves himself and kills for self-gratification. This man is the latter. If you want to kill in a war zone,it is easy, it doesn't take skill. It does however take skill to fulfill your mission, your duties to your men whilst ensuring that no life is taken needlessly. This man only takes life, and I wonder how much was necessary. Did he really feel remorse for shooting civvies or does he feel that is just the right thing to say. Sounds plain trigger happy with no sense of discipline. Lets not get patriotism mixed up with collusion with self satisfied killing.
