Marshal of the Soviet Union Lavrentiy Pavlovich Beria
Beria was one of the worst phenomena produced by the Stalinist Bolshevik system. He has a significant share in the unfortunate fate of millions of Soviet and foreign citizens. He was not, unlike some of his predecessors or colleagues, a "mentally limited butcher" and he was also blessed with some insight, but this in no way diminishes the gravity of his negative deeds.
