It is not strictly the same, but Marx enabled the tragedies of the 20th century with his philosophy. Crucial points are vague (he, for example, said almost nothing relevant about socialism) and the teleological force of his assumptions created a kind of infallibility framework exploited by the dictatorships to justify their deeds. The communism practiced behind the iron curtain was a perfect valid interpretation of his work. I recommend a really big book called 'Main Currents of Marxism' by the late ex-communist polish philosopher Leszek Kołakowski.
