War Behavior

I don't get it.  There is this big uproar about marines urinating on enemy corpses.  I agree that this is bad behavior.  What I don't get is that the people who are so outraged, don't seem to mind the whole idea of the war, and what it does to a person.  It seems that war is acceptable, but be nice, at least on camera.  War is horrible and it solves nothing in this day and age.  It turns individuals into the worst kind of person when they fight the war.  This bad behavior is the result of something that should not be happening at all.  I think that we should turn the running of countries over to women.  They could not do worse than the men.  Is war a man thing?
