This chapter outlines the book’s contributions to the interdisciplinary literature on femicide perpetration, with a particular focus on sociology, anthropology, and criminology. It examines key trends in the study of femicide, the slow shift towards perpetrator studies, and the persistent lack of attention given to the views and lived experiences of those who commit these crimes. I argue not only for the importance of understanding the stories underpinning intimate femicides as told by perpetrators themselves but also for how the absence of such research has misled current scholarly discussions. The chapter also addresses the significance of the terms used to refer to men charged with femicide, their theoretical implications, and, more broadly, the often-overlooked role of language in comprehending violence.
