Ironically, it is Marx’s accusers who would make human beings passive victims of fate. They say that Marxism is a ‘teleological’ theory, according to which all of human history is preordained. They even accuse Marxism of being a religion, with the role of God replaced by iron laws of history, leaving no role for active, conscious human beings to change history.
This is, of course, a caricature. Marxism is the only philosophy that explains the contradiction between free will and determinism. It is only by understanding the objective laws that govern society that we can change it.
