I think that he's a thief and a swindler.
Honestly, what good comes out of releasing all this info? This world is already on thin ice, it won't take much for WW3 to happen.
The release of these cables only empowers countries like Iran. It gives them even more of an excuse to paint themselves as victims and now they have proof that not only is the U.S against them, but so are the other middle eastern countries. The middle east is unstable enough, and this only increases that instability.
Heresy already shredded this portion of your post, so I won't duplicate his work.
It's like when you talk to your boys about your girl, not everything you say is going to be good so how would you feel if it got back to your girl what you were saying?
That, however, is a terrible analogy.
In reality it would be like if you hired your boy to go talk to your girl (on your behalf and dollar) and then he didn't tell you what they talked about.
Then your third friend who happened to find out what they did in fact talk about, was giving you the information behind the back of your friend whom you had hired to talk to your girl.
Upon hearing that, the friend you hired to originally do the job then set out to defame and or/kill the 3rd friend divulging the info you paid for - and vilifying you for getting any information from your 3rd friend in the process.
