Building on Rai and Fiske's (2011) Relationship Regulation Theory, we argue that violation of relational motives will predict the perception of the moral wrongness of moral transgressions better than violation of harmlessness or purity. We also argue that "metarelational threat" plays an important role in determining the degree of moral wrongness of a particular act. To test our propositions, we conducted 6 studies, 3 with Turkish and American respondents.
