Our good and morally upright behaviour is based upon our intrinsic moral rectitude and ethical compass. It has nothing to do with god and religious tenets. A moral person’s noble behaviour is not regulated by his love for god or fear of divine wrath. While saving someone, do you think whether any god up there will reward or punish you? You save regardless of anything in return.
The tragedy of mankind is that our embedded morality has been hijacked by an imaginary god and all man-made faiths. To be moral is to be driven by the pangs of conscience.
You’ve a quintessential example of the great French existentialist Albert Camus. Despite his atheism, he was a humanitarian par excellence who fought against apartheid, slave trade and was a tireless upholder of human dignity. Doing something good because that will make god happy is just like bribery. This is a sheer business proposition.
