"Now tell me , what is wrong with this logic ? If evolution is true , then you can decide anything for yourself . Nothing stops you ."
"And what does stop you ? You could decide that for yourself . But that would n't make the action just or moral . That action would still hurt people , and it would still be evil . So perhaps I should ask , if God were not threatening religious people with Hell , would they still be good people ? Or are all of the selfless and generous actions of religious people stemmed from the selfish desire to get into heaven ? If they are not stemmed from their own selfish desire to enter heaven , then they are they not rooted in that individual 's own desire to help others . This exists in some people . For those in whom it does not exist , we have the law . We create governments to do that which is in our best interest and that which is in our best interest is that which helps everyone . For that which harms someone else might soon be that which harms us . I have oversimplified what is a very complex understanding of morality , but the point is that the morality of an atheist does not begin with the desire to enter heaven , it begins with the desire to help others or create a society which will help everyone ."
