Marxism has always opposed freedom. I will quote just a few words from the founding fathers of communism, Marx and Engels
(I quote from the first Soviet edition of 1929)
"Reforms are a sign of weakness" (vol. 23, p. 339);
"Democracy is more to be feared than monarchy and aristocracy," (vol. 2, p. 369);
"Political liberty is a false liberty, worse than the most abject slavery" (vol. 2, p. 394).
In their correspondence Marx and Engels frequently said that after achieving power, terror would be indispensable, that "it will be necessary to repeat the year 1793. After achieving power, we'll be considered monsters, but we couldn't care less" (vol. 25, p. 187).
Communism has never concealed the fact that it rejects all absolute concepts of morality. It scoffs at any consideration of "good" and "evil" as indisputable categories. Communism considers morality to be relative, to be a class matter. Depending upon circumstances and the political situation, any act, including murder, even the killing of thousands, could be good or could be bad. It all depends upon class ideology.
And who defines class ideology? The whole class cannot get together to pass judgment. A handful of people determine what is good and what is bad. But I must say that in this very respect communism has been most successful. It has infected the whole world with the belief in the relativity of good and evil. Many people besides the Communists are carried away by this idea today.
Among enlightened people it is considered rather awkward to use seriously such words as "good" and '"evil." Communism has managed to instill in all of us that these concepts are old-fashioned concepts and laughable. But if we are to be deprived of the concepts of good and evil, what will be left? Nothing but the manipulation of one another. We will decline to the status of animals. Both the theory and practice of communism are completely inhuman for that reason.
