A good soldier is a blind, heartless, soulless, murderous machine. He is not a man. His is not a brute, for brutes kill only in self defense. All that is human in him, all that is divine in him, all that constitutes the man has been sworn away when he took the enlistment roll. His mind, his conscience, aye, his very soul, are in the keeping of his officer. No man can fall lower than a soldier-it is a depth beneath which we cannot go.
