The aim of the present study is to examine the mediating role of social safeness on the relationship between vengeance and life satisfaction. Participants were 305 university students who completed a questionnaire package which includes the Vengeance Scale, the Social Safeness and Pleasure Scale, and the Life Satisfaction Scale. According to the results, social safeness and life satisfaction were predicted negatively by vengeance. On the other hand, life satisfaction was predicted positively by social safeness. In addition, social safeness mediated the relationship between vengeance and life satisfaction. Together, the findings illuminate the social processes underlying the association of vengeance with life satisfaction.
