I live my life as I see fit. I do good works and am a good person because I have to look in the mirror at the most critical person of my life. Not because skydaddy told me to be good. And in your case, what fucking good is that even? You do as you please and Then ask your imaginary friend for forgiveness, wiping your hands clean of any type personal responsibility.
Atheists do what's right because it's right.
Not out of superstitious fear of punishment or hope of reward.
