I'm shaking with rage after reading that. Behold the consequences for acting according to one's conscience, as all human beings should. Reminds me of Battle Royale. Beat it into people's heads that good intentions only get you stabbed in the back, because they can never unite as long as they believe that.
The road to hell is paved with the best of intentions.
Not that Manning's intentions were good so much as they were petty and stupid... "Oh, I'ma get them militaries by stealing all these random messages sent by people who were not them to people who were also not them and sending them to a random third party!" He was disgusted by small, isolated incidents he felt his direct superiors mishandled, so he stole documents
from an entirely different branch of US operations and leaked them, without regards for their contents. In doing so, he put his head on the chopping block, and, quite hilariously, accomplished exactly nothing that he wanted, aside from a smug sense of self-importance.
You also - and this is the really big thing I keep trying to drill into your head - don't understand that humans are inherently self-serving. It gets a little fuzzy when you look at close circles of friends, family, and even mere neighbors, since generally benefiting (or often just being seen to benefit) the circle is the most advantageous course of action, since by fostering an environment in which such happens the others are more likely to benefit you as well. But then there are the people outside your circle. They don't benefit from your wellbeing, though occasionally they benefit from appearing to care about you.
This is the crucial flaw of Anarchism: believing that such people don't exist, or that they could be stopped from exploiting others, often coupled with an insane notion that this is all just a western phenomenon rooted in Dem Gubmints being evil, despite those very governments being the closest damn thing to an exception to all this that has ever appeared on such a scale in the history of humanity. There is corruption and folly, but less so than in humanity as a whole, and the structures have wound up fairly benevolent, which is absolutely amazing when one looks at history, and even at the other contemporary powers, next to which they look like fucking saints.
Then there's the No True Scotsman you keep pulling, where someone is only "acting with their conscience" or "with good intentions" if you personally agree with what they're doing. I suppose it really is inconceivable that anyone could ever think something you don't like is morally right, so obviously everyone that does anything you disagree with is evil, because I mean, what's right is just so glaringly obvious to everyone, not to mention universal...
