I'm not going to try to defend the Apache crew - who knows what Int that had on the victims in that video, but it looks indefensible on its own - but I will say that the Forces need people willing to kill. Not nice, but true.
The ideal soldier is one who is indifferent to death, and will kill if and when necessary, but not otherwise. I've never experienced it, but I doubt if there's anyone who has no emotions at all in that situation. So, taking it to extremes, we've got the choice of the soldier (or sailor, or airman) who enjoys killing, and spends years telling his mates about it in the bar, or the soldier who abhors it and, after his first kill, never touches a weapon again. Who would you rather have defending your country? And who would you rather spend millions on training to fight?
As I said, I haven't been there, and I wonder if anyone who hasn't can really comment. But is someone who enjoys his job such a bad thing?
