The next issue of the Journal GenObs will attempt to link responsibility, accountability, culprit, and extreme political violence to further understand what leads to the systematic discrimination of a group of citizens, and how they enact it. Through testimonies (biographies, archives, movies, propaganda, etc.) left by those who planned it, those who participated in it, those who tolerated it, and those who suffered it, we will explore their terms and forms, as well as the perception they might generate. We will question how memory and testimony interact when they occur in or as an act of remorse/repentance/contrition derived from guilt, or how some actors can experience certain guilt without it leading to recognition of their responsibility or accountability.
