Are children naturally born good or bad?

I read one of my friend posts today. He claimed that humans were born naturally good, only life lessons teach us to be bad. As I read further down I found a comment that disagree with my friend's claim. The comment claimed that humans were born naturally bad, we learn to be good as we grow up. Let's examine this classic argument. I think this will benefit us if we understand what is our nature and what changed that nature.
