I think that Che's ideology was based on the second one because you can see Fidel Castro and Che's division throughout their political career. Although they both believed in communism, you can tell from watching the documentary that Che believed in the good of all people. He criticized Soviet Union for trying to benefit only themselves and not the rest of the third world countries. He wanted to create this new Utopia where everyone would be somewhat equal, unlike Fidel Castro who wanted all the benefit and the profit to himself. Because Che believed in communist philosophy, he played a major role in the revolution and Cuban politics, which ultimately led him to leave Castro in 1965 to visit other countries.
