It is the punisher's mind-set where everything must be changed. The difficulty of this is explored in the superb book The Punisher's Brain: The Evolution of Judge and Jury {2014} by Morris Hoffman, a practicing judge and legal scholar.31 He reviews the reasons for punishment: As we see from game theory studies, because punishment fosters cooperation. Because it is in the fabric of the evolution of sociality. And most important, because it can feel good to punish, to be part of a righteous and self-righteous crowd at a public hanging, knowing that justice is being served. This is a deep, atavistic pleasure. Put people in brain scanners, give them scenarios of norm violations. Decision making about culpability for the violation correlates with activity in the cognitive dlPFC. But decision making about appropriate punishment activates the emotional vmPFC, along with the amygdala and insula; the more activation, the more punishment.32 The decision to punish, the passionate motivation to do so, is a frothy limbic state. As are the consequences of punishing-when subjects punish someone for making a lousy offer in an economic game, there's activation of dopaminergic reward systems. Punishment that feels just feels good.
