I don't see how you can't agree with their dying, it's a fact, hardly an opinion.
They do like dogs, although perhaps even with less dignity. In the Great War, we didn't have the time to bury them. They would either be carted off in a pile, chucked into a mass grave, burned to stop the smell and the disease- there was no sweetness in their death, no victory, nothing glorious.
I say it was for no good reason because they were fighting for an authority figure, for a government- and people on both sides thought that they were fighting for the right cause. But they were killing each other without being capable of having access to an objective viewpoint on the actual war. They died for a scrap of land no bigger than a postage stamp.
I do not set out to criticise the soldiers in any way at all. I would have signed up myself if I hadn't been medically incapable. I was so eager to go to war that I was a medical volunteer. But I speak from experience in that field. They died in agony, screaming, bleeding, body parts missing, every minute of every day.
