He didn't say life should be fair, he took the responsibility for himself.Who gave you the idea that life should be fair?
The Rabbi responds “God created atheists to teach us the most important lesson of them all – the lesson of true compassion. You see, when an atheist performs an act of charity, visits someone who is sick, helps someone who is in need, and cares for the world, he is not doing so because of some religious teaching. He does not believe that god commanded him to perform this act. In fact, he does not believe in God at all, so his acts are based on an inner sense of morality. And look at the kindness he can bestow upon others simply because he feels it to be right.”
