Why is it Assange's fault about what people do with information?
Because he had the power to ensure no harm came from it. He controlled it, he edited it, he could have ensured nothing bad came of it. It didn't need that level of detail to do all the things you apparently want from him and think he can offer you and the world of the Xfactor (I'd recommend turning that off incidentally, you can control what is shown to you).
I think the arguments you make are rather naive actually, Assange is not a crusader we are not ready for, he is selective publisher of facts that suit him.
The one thing I'd agree with you about is that knowledge is power (though for different reasons I suspect)..Assange agrees with you too, look how much he is enjoying wielding it when it suits him. And withholding it when it doesn't.
I wonder how ready you feel for the truth about Ecuador. Assange won't be telling you that, that's for certain.
