Feeling Bad About Feeling Good? How Avengers and Observers Evaluate the Hedonic Pleasure of Taking Revenge

Four pre-registered experiments (N total = 2,039) investigated how people morally evaluate avengers who experience hedonic pleasure (vs. displeasure) after taking revenge and whether avengers themselves pick up on these moral evaluations by third parties. Victims who took revenge were judged as more immoral than victims who did not take revenge, especially when they felt pleasure from doing so (Study 1). Conversely, participants anticipated that others would perceive them as more competent (but not less moral) when imagining them showing visible signs of pleasure (vs. displeasure) about taking revenge (Study 2). Furthermore, showing signs of pleasure from taking revenge was attributed to greater competence than showing signs of displeasure from taking revenge (Study 3). On the other hand, feeling good about revenge was attributed to lower morality than feeling bad about taking revenge (Study 4).
