I don&#x27;t think your anger is a result of loss aversion, but rather the fact that someone committed predation upon you.<p>Civilization depends on an equilibrium where I don&#x27;t steal your property, and you do not steal mine. Civilization flourishes when everyone is in the cooperate-cooperate quadrant of the prisoner&#x27;s dilemma. When someone steals from you, they have violated this very basic principle. If you accept this defection without responding, then they will likely only defect more in the future. Thus maintaining the equilibrium requires you to respond harshly to even small defections.
