Was che guevara a bad person?

Personally i think he was a great person because he fought for the people and he represents bravery, justice,freedom, and revolution...and also he wasnt racist, he went to help out the rebels in the Congo and demanded equal rights for blacks at his address to the UN and he said he doesnt have any hatred against american people its just the government he hates... and yes he did execute people, but they were soldiers of his army who werent disiplined and commited crimes like rape, robbery, or any other crime.also dont answer unless you back up you opinion with facts
