Research in moral education demonstrates the pattern referred to as happy victimising (HV) does not emerge only among children. Adults also transgress moral rules and might feel good doing so; however, research reveals the HV pattern emergence is context specific. In contrast to findings among young children in whom the HV pattern was interpreted as a lack of motivation and thus a developmental stage, it is an open question as to what happy victimising in adulthood means and how such patterns affect intentions as an important step towards action. This paper offers an action-theoretical approach, allowing for reconstruction of the process of intention formation, as well as a systematic discussion of results from two separate lines of research: (1) research on patterns of moral decision-making, such as the HV, and (2) research on moral disengagement. Additionally, a survey study provides insights into what intentions, emotion attributions, and moral disengagement strategies adults display in situations of low moral intensity, and whether they indicate consistent or contradictory patterns across situations. Results indicate intra-personal consistency regarding patterns of moral decision-making, but also show there are participants who vary these patterns across situations. Moral disengagement strategies were shown to have context-specific use, at least in regard to their subcategories. Regarding education, this study encourages not only a focus on strengthening the moral self or autonomous moral judgement but also on paying attention to actions and person-situation interactions. This might be useful to implement environments that support reduced application of moral disengagement strategies.
