This article is part of an ongoing research on the representation of genocides in documentary cinema. In this instance, the characteristics of the testimony of the victimizer in documentary cinema will be investigated, mapping different productions. A possible scheme will be presented that will pay attention to the narrative matrix of the testimonies and the modes of responsibility that are exposed therein. In this way, two main poles will be presented, oscillating between the interview –more linked to providing “objective” information– and the confession work –where the perpetrator meditates on his subjectivity–.
