Most of the people who get sent to die in wars are young men who've got a lot of energy and would probably rather, in a better world, be putting that energy into copulation rather than going over there and blowing some other young man's guts out.
There are people. There are stories. The people think they shape the stories, but the reverse is often closer to the truth.
I've known a lot of people go mad over the years, and it is more distressing than people dying. People dying is quite natural, people going mad is the complete antithesis of that.
