The authors suggest to ponder on the topic of a rise of acted violence in the adolescent population and question the psychoanalytic understanding of destructive both heteroaggressive and self-aggressive movements. Several theoretical positions on the topic of the death instinct, or of drive unbinding or an attempt to save a feeling of identity when violence surges are analyzed briefly, followed by two clinical vignettes. From the latter cases, they try to link the intrapsychological and family links underlying the recourse to violent actings with such subjects, as related with adolescent problematics. The temporary identification dilemma is here suggested as well as the interdependence between self-violence and violence towards the other person.
