The article presents the findings of a psychosocial intervention process with affected people and offenders in the Colombian armed political conflict. The intervention was oriented from collective memory contents collected through life stories in the Metropolitan Area of Bucaramanga, Colombia. The first conclusion based on social constructionism is the shift in the nomination of the actors in conflict: victim for affected, victimizer for offender, civil society for offended. At the end of the process five categories were defined which were common to both populations and one which was specific to offenders. The common ones were: temporality, causality, facts reported, feelings, and coping. The specific category of the offender community was Life- Experience in the armed organization.
