Vengeance is mine: Narcissism, vengeance, and the tendency to forgive

Recent theory and research have suggested that the disposition to forgive and the tendency to seek vengeance are related but distinguishable characteristics. Although highly forgiving individuals cannot be simultaneously high in vengeance, those who are low in forgiveness could be either vengeful or not. The present study tested the hypothesis that what distinguishes unforgiving people who are highly vengeful from unforgiving people who are not highly vengeful is that the latter group is lower in narcissism. Measures of dispositional forgiveness, narcissism, global self-esteem, and vengeance were administered to 248 undergraduates. As expected, people low in dispositional forgiveness were more vengeful than were people high in dispositional forgiveness, but particularly so among those high in narcissism; among those low in narcissism, forgiveness was less strongly related to vengeance. Thus, the most vengeful people were those who were both low in forgiveness and high in narcissism, independent of gender differences and healthy self-esteem.
