Mere belief and mere atheism are amoral philosophical positions. Some people spent a good deal of time and effort to seek his/her answers. I applaud them regardless of the outcome. Some people are just lazy to seek their own answers and take it for granted. It's not a fault and it doesn't matter. In any case, we cannot fault people who honestly believe or disbelieve for whatever reason they may hold or not hold and by the amount of effort he exerted to support his position. But we do take interest in people who will coerce others to subscribe to their own philosophical/moral position by using threats or abuse mentally (teaching children punishment of hell for "sins") or physical harm and even murder (Crusaders & jihadists). I subscribe to the idea that individuals are free to believe what they believe or not believe as long as it never harm another person and that he has no right whatsoever to force this belief or non-belief on others. So the communists did bad things to persecute the believers and the Catholics and Protestants did bad things to persecute the heretics.
Theism (belief in god(s)) or atheism are fundamentally amoral -isms. It's in the conclusions that supposedly follow from these two -isms that address morality that gets us into trouble.
