In today's world, schools, especially in places with a low human development index, can become a factory that imports, resinifies and exports new forms of violence to society in an endless cycle. In order to separate this snake that bites its own tail, in this manuscript I propose systematised violence as a pedagogical tool and possible vaccine to combat the endemic violence in schools. To do this, it was necessary to analyse some of the pillars of this phenomenon, such as the influence of students' family groups and boredom on the increase in violence within schools. In order to understand this scenario, the qualitative methodological resource used was a case study, using observations, focus groups, semi-structured interviews and life stories as research techniques. Far from bringing the subject to a close, the intention of this project is to provoke reflections on new proposals for reducing school violence, from a new perspective.
