It is bias to think that the art of war is just for killing people. It is not to kill people, it is to kill evil. It is a strategem to give life to many people by killing the evil of one person.
Yagyu MunenoriWhen you strike a blow, do not let your mind dally on it, not concerning yourself with whether or not it is a telling blow; you should strike again and again, over and over, even four or five times. The thing is not to let your opponent even raise his head.
