Do Atheists and Agnostics Do Evil Acts or Think Evil Thoughts?

There is a thread of the atheist vs Christian debate that has both sides believing that Atheists don't wish to follow Jesus because they would need to give up their evils ways.  Honestly, most intellectual atheists don't seem to fit that pattern.  On the other hand, practical atheists or nominal believers would commonly fit that statement.  They may be hard party folks, given to sexual sin, desiring to keep lying, cheating on taxes, etc. 

In fact, I would go so far as to say, most atheists I have debated at length are more inclined to think that they are not sinners, and thus would have no need of a savior.  A very close friend of mine has stated that they never lie, cheat, steal, etc.  And from what I know of this person, he/she might be close to correct. 

So, I'm curious to hear from non-believers.  Do you do acts which you consider to be very inappropriate and worthy of judgment by somebody?  Do you fail to do things that you probably should do that if these failings were known would cause others to judge you harshly?  Or do you see yourself as being very, very nice, friendly, unselfish, law abiding, etc.  If yes, is it possible that you project your perfection onto others and believe that were it not for .... fill in the blank .... bad parenting, government, religion, poverty, bad luck, bad friends .... that everyone would be close to perfect like you.   I know this last bit seems a bit "nasty," but I can't think of another way to get the subject on the table.

If you spend a bit of time in the atheist websites, I think you will gather that most atheists see themselves as better than others, much smarter and certainly wiser.  But they also see themselves as not needing anyone to help them make wise decisions.  They would be the "good person" that many of liberal political thought think is the norm.

Where have I gone wrong?
