Dante´s hell is divided in 9 concentric circles, each circle dedicated to a different kind of sin (Dante´s sins, which are an interpretation of Aristotle´s Ethics, condemn vices of the body and misguided appetites, and vices of the mind or faults related to unreasonable behaviors). The last circle of hell is dedicated to people who have committed treachery, specifically treachery towards other people who were close to the sinner, like family, but also the community and society and authority figures.
