I view them both very negatively. I can see Snowden as “Lost Boy” being fooled and that at least elicits some sympathy, but Assange is wicked to the bone because he has a lot of blood on his hands.
Some people are willing to forgive Assange because he helped Trump. He did that because he hates America and thought Trump is going to harm it.
You might chuckle at that if it were just that, but his actions also caused all these American and allied troops dying to IED-s or American friends and other good people ending up tortured and killed because of what he did.
