Very few followers of Marx have ever read him. He is what ever they want him to be.
When he was living in London he spent a lot of time at the library reading Adam Smith. He read what he considered at the time the foremost author on capitalism. Why did he do that? Turns out he was learning in order to smash it. Not a dummy. He was trying to figure out a way to recreate the French Revolution. And, he wanted to create a world which would enslave all but the ones most worthy. And, all would worship Satan whether they knew it or not.
From Rev. Richard Wurmbrand we learn that Marx was possessed by Satan from his book Marx and Satan.
