Whether or not you think that information should be out there, protecting national security secrets was quite literally his job. Penalties for mishandling national security information are pretty clear, especially when you've been put into a position of trust. He then flees to one of America's biggest enemies on the international stage. And do we really think that protection came without a price?

Honestly I have real mixed feelings about Snowden. I do think Americans had a right to know about the domestic spying activities even if they weren't entirely surprising (details had been leaked previously but we did not know the degree to which those efforts had been ramped up). But he openly and knowingly violated the law. He can't have expected that to come without consequences. And he can't fall back on principles if he's not willing to face those consequences.
