The Dark Triad (Machiavellianism, Narcissism, and Psychopathy) is a set of three subclinical antisocial and socially manipulative traits with common characteristics of questionable moral reasoning. Those traits share a common core in the underlying empathy deficit, whereas empathy itself can consist of two dimensions. Cognitive empathy allows a person to recognize and understand the empathic expressions of others, while affective empathy allows that individual to experience with another person. The theory of dual processing assumes that there are two ways by which persons make moral judgments; one is emotionally grounded and leads to deontological decisions, and the other is rational and leads to utilitarian ones. Accordingly, this study examined the importance of rational and experiential thinking style in the process of moral decision making. The aim of the research was to examine the connections between dimensions and then to induce empathy in the Dark Triad and to look at the change in the response to moral dilemmas. Predictors of individual responses were also examined. The results showed that the Dark Triad recorded deficits of affective empathy, and both Machiavellianism and psychopathy and cognitive deficits. Machiavellianism was negatively related to a rational style of thinking and narcissism positively. Cognitive empathy was related to both rational and experiential style. The induction of empathy unexpectedly changed the answers from deontological to utilitarian. Prior to induction, affective empathy was a predictor of deontological responses and psychopathy of utilitarian responses. On the other hand, after induction, Machiavellianism and psychopathy proved to be predictors of utilitarianism. The findings make a valuable contribution to our understanding of the relationship between the Dark Triad, empathy and moral decision-making.
