There is a book written by Richard Wurmbrand-Marx & Satan, in which he points out, that although Marx had Christian beliefs growing up, he turned against God later in life and worshipped satan.
Wurmbrand was imprisoned in Europe for 14 years due to his outspoken views on communism.
Wouldn’t surprise me. Marxism seems to have a foundation in envy, and for that matter, every other negative character trait. It turns every single one of the Ten Commandments on its head.
