" Vengeance was a necessary function of a civilized world, particularly at its margins, in its most remote and wild regions. Evildoers, unwilling to submit to the rule of law, needed to lie awake in their beds at night worried about when justice would eventually come for them. If laws and standards were not worth enforcing, then they certainly couldn’t be worth following. "
