Tearing apart psalm 14:1...your thoughts?

I don't take this as a "if one is true then all are true" situation, it isn't just the denial of God, but their corruption and misdeeds that make some people bad. I don't think that's necessarily saying that all people who don't believe in God are bad, nor does it imply that all people who do bad things are Atheists, but simply that people that do all of these things are fools.
