War

When we are thinking of engaging in war, I suppose that we are assuming that mostly the wrong people will die and subsequently lose, and the right people will mostly live and win. Even if we think there is no chance of surviving we still often justify war saying; “at least the wrong people will have to pay”.
“Give me liberty or give me death” comes to mind. Fear drives people to such insane measures. Leaders often exploit fear (ignorantly) if even on purpose for their own benefit.
