Far more than any other period of life, adolescence is the container of a whole series of processes already inscribed within the child at birth. It is according to an adequate answer from the objects that these processes will reach full development. Violence to be will then take the shape of a life project, i.e. the expression of the superego signing the completion of adolescence. Such is not the fate of sexual aggressors. Non integrated violence leads them to let their ego being dissolved in the interplay of several processes. The aggression of the other person thus becomes a defence against an hallucinatory intrusion.
