You sound ridiculous. Let's get to the real question.
> So because there happened to be something bad among the 250k documents, the act itself is completely absolved?
In short, yes. Her 7-year sentence has already been quite enough.
I will concede that the outlet through which the leaks were published didn't meet the standards to which we usually hold investigative reporting. Manning chose to disclose all cables in confidence to a team she felt could sift through them for evidence of wrongdoing. That team then proved themselves irresponsible by publishing everything. They should have been far more selective about what they disclosed to the public.
I don't blame the source here. I absolutely do blame the coverage.
