ABSTRACT: In the collective aggression, the group's supervision and leadership activity is coordinated by a single person, whom all other individuals focus on, due to the domination, prestige and influence of the person on the collectivity. The intellectual factor of the leader lies in the way of conceiving the model of leading society and dominating the social movements. The volitional factor indicates the energetic-dynamic dimension of the leader's personality, as well as the support of the intellectual element through which the meditative approach is conceived as a non-retroviral movement. The psychic identity of the leader has a unique structure, because the component elements determine the consciousness of personal identity. The behavior of the criminal leader is dynamic, his thinking and affectivity mobilizing the personality system. The criminal leader imposes on the group its own needs. In terms of association, the conduct of the members of the criminal group is different, so there are common elements of the subjective aspects specific to the offenses, an agreement of will, interests, respectively coinciding. However, committing a crime by a member of the criminal group does not automatically entail the criminal liability of all members of the criminal, aggressive group.
