In this article we seek to identify elements that make up part of a cartography of power, a sequence of works related to a larger research. Through the criminal processes of Mallet-PR in Brazil, it was possible to find points that suggest a quite latent morality in society that configures an exercise of power, crossing subjects, institutions and knowledge. When that moral was broken, the response was almost immediate and violent. From this, we will see how the frontiers of legality, right and wrong, good and bad lose their dualistic character, getting confused and reconstituted in other forms of relationships. We identify here, a violent process of maintenance of morals. We deal with conceptualizations throughout the text, with emphasis on violence relations in the first moment, continuing with the questioning of morality in the second moment. We hope that this conversation with history and philosophy will allow everyone a critical reading of their own social place.
