Perpetrators of mass atrocities can be victims of trauma. What does this tell us about perpetrators specifically and human nature more generally? How does such trauma develop? And should we even be concerned about perpetrator trauma? In the final episode of season two of Terribly and Terrifyingly Normal?, we discuss the concept of perpetrator trauma and the associated moral dilemmas together with Bart Nauta. He is currently doing his Ph.D. on the topic.
