For the Bolsheviki the end to be achieved was the Communist State, or the so-called Dictatorship of the Proletariat. Everything which advanced that end was justifiable and revolutionary. The Lenins, Radeks, and Zorins were therefore quite consistent. Obsessed by the infallibility of their creed, giving of themselves to the fullest, they could be both heroic and despicable at the same time. They could work twenty hours a day, live on herring and tea, and order the slaughter of innocent men and women. Occasionally they sought to mask their killings by pretending a “misunderstanding,” for doesn’t the end justify all means? They could employ torture and deny the inquisition, they could lie and defame, and call themselves idealists. In short, they could make themselves and others believe that everything was legitimate and right from the revolutionary viewpoint; any other policy was weak, sentimental, or a betrayal of the Revolution.
