At this historical juncture, for Arendt, it became necessary to conceptualise and prepare for crimes against humanity, and this implied an obligation to devise new structures of international law. So if a crime against humanity had become in some sense “banal” it was precisely because it was committed in a daily way, systematically, without being adequately named and opposed. In a sense, by calling a crime against humanity “banal”, she was trying to point to the way in which the crime had become for the criminals accepted, routinised, and implemented without moral revulsion and political indignation and resistance.
