This article seeks to analyse the life histories of two former members, Patroklos Tselentis and Sotiris Kondylis, of the defunct terrorist group, the Greek Revolutionary Organization 17 November (1975–2002) in order to look for causes of disengagement, dissociation, and repentance. Analyzing the life histories of Patroklos Tselentis and Sotiris Kondylis offers valuable insights into the development of complex processes of involvement in and disengagement from 17 November terrorism. Disillusionment with the effectiveness of 17 November’s activities and the failure to justify the necessity of other group members’ proclivity for violent activities were identified as factors leading to doubt, and ultimately exit. Another factor was the inability to have a personally satisfying life in Tselenti’s case. Interestingly, neither Tselentis nor Kondylis speak of facing any violent objections to their intentions to leave the group, which likely made exit a lot more viable.
