If you have to look along the shaft of an arrow from the wrong end, if a man has you entirely at his mercy, then hope like hell that man is an evil man. Because the evil like power... they will talk, they will gloat. So hope like hell your captor is an evil man. A good man will kill you with hardly a word.
