If Snowden blew the whistle (to the minimum extent possible to inform the public about what was happening) and stayed in the U.S. to face the music, I could buy the argument that he was a hero and deserves a pardon. What he did instead is that he fled to our biggest foe and revealed publicly a lot of tactical information that only serves to hurt U.S. intelligence operations abroad. Further, we will never know what he sold to Russia to earn his welcome. Now he's a part of a propaganda machine of a tyrannical regime. Sorry, but that makes him a Russian agent, traitor and a dirtbag.
