While he erred in a number of respects, Che is deserving of a place in the 'Pantheon of Heroes', or 'list of good-natured people who saw that we're all in a prison and wanted to help others break free'.
I agree with this. He might have been wrong in many things, but my impression is that he was a good-natured person who really wanted to do something for the people.
I once read a book called Cuadernos de Praga (it would be "Prague Notebooks), "Guevara's notebooks written during his clandestine stay in Prague in 1966", according to Wikipedia. It was a good read and I really enjoyed reading his own thoughts for once. He was passionate, very sensible and thoughtful in my opinion, but of course, passion can bring us to do things that might not be the best. The book also shows his own doubts, his inner struggling, which I think show he was a human, with his virtues and mistakes.
Maybe, sometimes, we want to cover the ones we would like to put in that "Pantheon of Heroes" with an "all-good and pure" blanket, but the truth is that they are all human beings, not perfect, just as we are. They just seemed to fight for something which was bigger than themselves, for freedom, etc... so they deserve to be remembered, OSIT.
About he being a "homicidal maniac", well, that's the sort of thing that we hear about Caesar at school... and about Putin nowadays... that should give us a clue, I suppose.
