Who killed Che Guevara?

Shot answer: The Butler, it is always the butler.

Long(er) answer: The executioner killed Che. He was leading a revolution and had been caught. What better way to make an example out of someone than to kill him? He was subverting the established government in favor of a radical and unstable government type. He was captured by the Bolivian Army and executed. This executioner was probably a member of the Bolivian army/government. Had Che not been such a radical, he probably could have avoided being killed. So I guess in the end, it was really Che's ideals that got him killed.

At one point, Che was one of the most wanted men in the world. The United States government trained rebels to catch him, but he often slipped away back into hiding. The cat and mouse game went on like Bugs Bunny and Elmer Fudd, Road Runner and Wile E Coyote. They never could catch Che, he was always a step ahead, until one day, the rabbit stopped saying "Whats Up Doc?", the road runner stopped running, and Che was captured and killed.
