In Dostoyevsky's prophetic book "The Possessed" he vividly unmasked the evil face of socialism. Among other things, one of the characters advocated the "hundred million heads theory", which was that to make real progress in the establishment of a socialist utopia, 100 million heads would have to roll. At the time, I am sure many criticized Dostoyevsky for being over the top. As it turned out, he underestimated how bloody they would actually be.
Every time socialist utopians have attempted to establish their utopias they have in fact established hells on earth. The Communists killed about 100 million people in China alone, and it has only ceased to be less of a hell hold to the extent it has departed from Communism.
