"There's a principle of ideology that we must never look at our own crimes. We should on the other hand exult in the crimes of others and in our own nobility in opposing them."

I believe the quote is from Noam Chomsky but couldn't find any references. Some interesting debate in this thread, but as you and the OP say, there is no black and white, good vs evil, just many shades in between with many actors playing many roles simultaneously. Fidel Castro was certainly no saint and at times was the devil, but there were also those other times inbetween.
