Note the date.
Here's the quote:
"I carefully evaluated every single document I disclosed to ensure that each was legitimately in the public interest," he said. "There are all sorts of documents that would have made a big impact that I didn't turn over, because harming people isn't my goal. Transparency is."
The article itself continues immediately:
"He purposely chose, he said, to give the documents to journalists whose judgment he trusted about what should be public and what should remain concealed."
His first sentence said "...every single document I disclosed..." (emphasis added). Note how he didn't say "every single document I copied from NSA"; he was referring to documents he disclosed, and those documents were only disclosed to the journalists you're referring to.
What this means is that if a journalist ever showed you a Snowden leak at all, it was because it passed through Snowden's self-professed "carefully evaluated" disclosure review.
Stop blaming the journalists, Snowden himself specifically said that if those journalists have any of his documents at all, it was because Snowden intended specifically for them to have it.
What's worse, even if it were true, your conclusion doesn't make sense and is just a cheap shot based on your own political views. Nothing about his stated motives are undermined by these releases, whether you agree with his actions or not.
