Collective harm-doing: Developing the perspective of the perpetrator

This Special Issue on collective harmdoing aims to explore, from the perspective of the perpetrator, the association between harmdoing and well-being, and the processes through which people engage and disengage from harmdoing. We present 6 articles, comprising 3 theoretical analyses and 3 empirical articles, that represent a diversity of perspectives on manifestations of collective harmdoing from youth violence to genocide, and from soldiers in combat to terrorism and counterterrorism. A discussant piece, as well as this introduction, together consider the themes, achievements, and omissions of the special issue.
