IN MY FIRST KNIFE FIGHT I learned that there are two kinds of people who enter a deadly conflict: those who kill to live, and those who live to kill. The ones who like killing might come into a fight with most of the fire and fury, but the man or woman who fights just to live, who kills just to survive, will usually come out of it on top. If the killer-type begins to lose the fight, his reason for fighting it fades. If the survivor-type begins to lose, his reason for fighting it flares up fiercer than ever. And killing contests with deadly weapons, unlike common fistfights, are lost and won in the reasons that remain when the blood begins to run. The simple fact is that fighting to save a life is a better and more enduring reason than fighting to end one.
