I have to admit to mixed feelings about Edward Snowden. On the one hand, a government needs to keep some secrets, and betraying those secrets can cause great harm to the country. On the other hand, it looks like our government has been participating in some illegal and immoral actions, and from that perspective Snowden is doing the right thing as a whistle blower.
Whatever his intent or the morality of his actions, it certainly took a lot of courage.
