The traumatism that is generated by the terrorist violence in Algeria is affecting the victims' mental health and the social balance. The gravity of the psychic disorders observed in victims is in proportion with the lack of comprehension of those unexpected aggressions. Moreover, the terrorists are not safe from psychic troubles. The monstrous acts they are responsible for obviously have an impact on their psychic balance. Society has to prepare itself to help victims but also executioners, and to provide them a medical and psychological assistance. Agents of security services are concerned too, because of the threat to their life and their family. Torn between their desire to accomplish a work they are not trained to do and the suspicion they are facing they display behaviors that increase their rejection. Everybody is suspect, social balance is in pain. "Civil concord", that aims at bringing about a national reconciliation and at initiating a process of peace, could have perverse effects and constitute a factor of aggravation of the observed social disorder. A feeling of injustice could arise if the terrorists' amnesty is perceived as an absolution that disqualifies the victims' mental suffering. The latter would be victimized again. In this case, the restoration of the social bond would be jeopardised.
