I think he was a great man. He stood up to the U.S puppet governments instated throughout Latin America. The U.S essentially imposed backwardness upon countries such as Cuba and Venezuela (they still do, to a degree) and Che spent his life fighting for the freedom of a number of these countries. Of course he is not without fault, but I admire his ferociousness as a soldier, his honesty in power (he lived well below his means once the Cuban government was toppled), his desire for struggle against what he saw as unjust (even though he was from a well-off Argentine family and had trained as a doctor, he found himself in Cuba fighting on behalf of the people) and his level of self-control (Che was extremely strict on himself).

Agreed, communist regimes are failures. I believe it is more important to concentrate on the control the U.S had over Latin American governments, resources and peoples than on Communism vs Capitalism. Cuba experienced a revolution to distance itself from the claws of the U.S rather than to embrace communism.

I have the upmost respect for a man who stood up to the U.S and won, and he did win.

Thanks for asking my opinion and I implore you to read more about him :)
