Marx was a socialist political philosopher, that helped define the social end goal of communism. Lenin was a militant revolutionary that thought he could ignore Marx's slow natural social evolution to communism. And force it under authoritarian boot heel. He was aspirationally communist at best, but not communist. His ideology has failed to achieve it everywhere it was tried. Generally, creating a new class of Petit Bourgeoisie or even collapsing into open fascism.
