Parties involved in intergroup violence tend to be portrayed in simplified ways, clearly dividing between those perceived as morally bad (often referred to as perpetrators) and those perceived as morally good (often referred to as victims). However, the process of intergroup violence is not as simple and includes a wide and more complex array of behaviors, varying in terms of moral evaluation (see Vollhardt & Bilewicz, 2013). One such rare and counter-stereotypical behavior, observed among the perpetrators and bystanders of collective violence, is a courageous act of helping victims under high personal risk. Implications of this type of behavior constitute the main topic of this chapter. Acts of help provided to victims by perpetrators or witnesses of collective violence are examples of morality crossing ethnic, national, religious, or ideological boundaries. It is important to accentuate that such help, provided under circumstances of hostility, often results in severe consequences for the helper such as ostracism, exclusion, or even loss of health and life for themselves and their relatives. The most widely discussed examples of such heroic actions are people who rescued Jews from death in extermination camps during the Holocaust, awarded with the Righteous Among the Nations Medal. However, such acts of heroic behavior have also been observed not only in relation to the Holocaust but also in contexts of other examples of collective violence in the 20th century. We refer to such acts using the term moral exemplars (Čehajić-Clancy & Bilewicz, 2017, 2021). In this chapter, we propose that exposure to moral exemplars is an effective intervention facilitating positive intergroup relations in post-conflict areas.
