see, in the end, that the concept of punishment must fend off confusion from many directions. It must hold its own against those who try to obliterate the distinction between punishing crime and imposing other sanctions for the sake of protecting the public. The concept must also secure its place in opposition to purely private institutions, such as wreaking vengeance and securing compensation for injury. The concept of punishment must straddle the delicate line between the public and the private, between the motive of protecting society and the motive of promoting the welfare of victims. The task of thinking lawyers is keep their focus on this delicate line and to cultivate the correct conceptual account of punishment.
