At the time of war there is no such thing as freedom. You are given a rifle and ordered to kill. If you disobey, you are killed, it's as simple as that. Try to be in that situation and then talk about responsibility.

Tell me, who was responsible for the hundreds of thousands killed in the battle of Verdun: individual soldiers? Scared to death, trembling, half-insane, playing dead under the dead, left without any reasonable choice, resembling more animals than humans? Or someone else, who actually sent them there?
