The contemporary normative climate regarding sexual violence affects how perpetrators of such violence relate to their harmful acts. In this article, we analyze how men convicted of sex offences are affected by how perpetrators of such offences are often represented as monsters and ask what this tells us about what characterizes the Monster as a figure. While people convicted of sexual offences are likened to monsters in many contexts, there is little research that unpacks the characteristics of this figure and how it is contingent on ideas about and the regulation of sex offending. By analyzing data from qualitative interviews with 17 men convicted of sexual offences in Norway, we found that, although they presented themselves and the acts they were convicted of committing differently, they had a common fear of being identified as a monster. In these narratives, a monster was characterized by (1) intentionality—having intentionally harmed others, (2) preference—having a sexual preference for harmful, nonconsensual sex, and (3) authenticity—being authentically violent. We conceive of the narrative processes that the participants engage in as forms of social abjection and discuss the consequences that abjection may have for accountability, rehabilitation, and justice.
