The author, starting from a general description of bullying, analyses the phenomenon from the psychoanalytic point of view keeping into account the complex overlapping of all factors, which at the psychic and socio-cultural level, enter into account in the treatment of aggressiveness. It is taken into consideration the connection between bulling and group and what differentiate it from gang, which is created by a coalition pact of offence of its members against what is external. The connection between aggression, violence and depression in adolescence is explored and it is also questioned the actual diffusion of bulling not only in adolescence and in pre-adolescence but also in latency. The distinction between a physiological aggressiveness essential for a transit to an adult age and disruptiveness is deepened. It is also taken into account the concept of "dynamics of the internal group" that is a pact of loyalty with an "internal group" which would act a defensive role against the scare of depression: bullying appears as the display of sadism in an internal organization which keeps the subject as a prisoner. The author facuses on therapeutic interventions, which he deems more useful, that is, the psychoanalytic psychotherapy and a scholastic work which is also preventive. A clinical case, at the end, exemplifies the work conducted with an adolescent victim of dynamics correlated to bullying, in an actual social context dominated by idealization of the body and a tendency to violence of the group.
