While I think it's true that he took too many documents and probably released too many documents, I think his intentions were good, and overall was an important contribution to public knowledge of the way our governments work. It was an eye opener for a lot of tech companies, to be sure.

He was essentially forced to flee to Russia-- no other country could protect him. I don't think it's where he wanted to end up.

I don't think he should be pardoned. He committed crimes, and possibly could have found a better way to get this information out there. I do think he should be offered a generous plea-bargain in return for coming home and debriefing the NSA/CIA and congress about what exactly he took, how he took it and the status of all of those secrets.
