This essay discusses the mass consent to enacted evil, in particular regarding National Socialism. It is suggested that the concept of legality played a major role in the creation of consensus from the perpetrators’ viewpoint. Legality contributed to consolidation of the regime and to its support because it reinforced bureaucracy and accelerated the Nazism’s criminal project. With the collusion of the amphibious nature of Weimar Constitution, full awareness and participation of the regime’s ruling class, zealousness of German jurists (judges such as Roland Freisler and Hans Frank, or theorists such as Carl Schmitt and Karl Larenz), the principle of legality favoured, together with other propulsive factors, the efficacy of the Führer’s power system, also regarding the consent of the civilian population.
