Why punish perpetrators of mass atrocities? Reflections on peace, punishment and the ICC

Ever since the trial against the major war criminals of World War II before the International Military Tribunal at Nuremberg the institution of 'punishment' has been an integral part of the international legal system. Nowadays a considerable number of perpetrators of crimes under international law – that is: genocide, crimes against humanity, and war crimes – are being sent to jail by international judges. But why and to what aim do we punish individuals for their involvement in mass atrocities? How can we justify punishment by international criminal courts and tribunals vis-à-vis the affected individual? Or more generally: What are and what should be the rationales for punishment in international law? Among the (few) answers given to these questions one relates to the claim that international prosecutions and punishment would contribute to the restoration and maintenance of peace ('peace through punishment'). Some scholars (and Courts) simply want to apply the theoretical concepts from the domestic context, such as retribution, deterrence, rehabilitation, norm stabilisation and so forth, to the realm of crimes under international law that ('domestic analogy'). The paper will present some preliminary reflections on these issues.
