This paper is the result of the research "Death drive and criminal acts in a group of inmates of INPEC - Pasto", completed in 2017, with the collaboration of the Mariana University and the inmates and officials of the National Penitentiary Institute and INPEC Prison - Pasto. The investigation was guided by the general objective of understanding the death drive in violent acts of a group of inmates of the Pasto Prison, which allowed for the design of an intervention proposal with the selected population. The specific objectives of the study were directed towards exhaustive reflection on three important categories: events, the unconscious mechanism of repetition and the process of subjective rectification; from a qualitative paradigm, with a hermeneutical approach and an ethnographic method as collecting instruments: the semi-structured interview, the life history, and the focus group. The study allows to affirm that, although in most inmates there are no high levels of antisocial behavior, the percentages of inmates who do present these levels should not be disregarded, since this implies a tendency to commit these behaviors during its life cycle.
