Nobody knows what God thinks or if he has any preferences at all. In my own humble opinion doing good is most important no matter what are person's beliefs. However, if a religious man does good only to earn a better place in afterlife, then atheist's motives are less selfish.
For a moment we'll put rational thought to one side and accept that there is an omnipotent God. By the very nature of that description he knows what is going on in the heart every human being from beginning to end-times. Do you not think that it is arrogant of any human to presume that he can know the workings of the mind of this being?
Doing good is relative! Ask yourself first, doing good to and for whome ... and then add the question "How can any non-existing, super natural entity care what any one does?
How a person sees himself determines how god sees him...god sees no religious affiliations atheism included.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
