"I was only doing it because i'm a careerist grifter and wanted to profit off my connections in the party, the slave labor and the assets stolen from deported Jews" was actually the second most common excuse after "i was only following orders" in post WW2 Germany. And basically all of these ghouls got away with it, many of them continuing to make stellar careers in finance, industry and politics. The damage they did by continuing fascist loyalties within the German ruling class is felt until today.
