Che Guevara...

Let's see, he overthrew a brutal dictatorship in Cuba, the result wasn't much better but it's not like fighting against Batista was something awful, he fought against a brutal dictatorship in the Congo and then died fighting a brutal dictatorship in Bolivia. What's wrong?

The French Resistance killed people while trying to remove a brutal dictatorship. That's that Che did.

So because the French killed people that is a blank check for Che to kill people?  I'm not following your logic.

He killed the supporters and defenders of oppressive governments, which is what the French Resistance did.

I'd say Castro is better than Batista, although obviously neither one is ideal.
