I really, really doubt that.
Reading that 400m of investor money was stolen (again, read) from the "biggest[or "one of the biggest"]" exchanges is 100% bad.
Go read any news article and check the comments on it. "I knew it was a scam" "Get rich quick fail" basically this re-assured everyone bitcoin was a scam.
Those people will never change their opinion so it doesn't matter what they think. It will have to get to the stage where they are using Bitcoin without evening knowing it before they recant.
For the people who were already thinking about getting into Bitcoin hopefully the gox failure will make them more cautious about who they deal with and how they store their coins. A good thing in my opinion.
