I sort of agreed with them when I was very young and knew everything.
Why should a man kill 5, 10, 20, human beings and then when he feels his own life in danger go, 'Whoa, don't want to play this anymore'.
Also the Geneva Convention, which they didn't recognise, was written by the upper classes for the upper classes. You could work/starve the poor old enlisted men to death. But the officer class, no work, extra rations and a free concert just to rub it in.
Tsk, twas ever thus.
