response to free speech

To me it seems that his motive is to try and help the U.S. but when i read things that say the consequencs of some of his leaks could be "potentially severe and dangerous" makes me think he is more of a traitor. If the U.S. Secretary of Defense is a witness against Assange, it makes me lean more towards the fact that these people are doing these leaks against the United States. I am confused though because when we watched the interview with Julian Assange he made it seem as though he was saving the world, this article made it seem as if he is hurting the U.S. ecspecially our military. Another thing from the article that makes me a bit untrustworthy is the opening sentence stated that he was in custody of having committed sex crimes. hm..
