The wrong question is being asked, IMO.
Considering what we know of human nature and man's propensity towards evil, the question shouldn't be *If there's a God, why is there evil and suffering in the world*, but rather *If there's no God, where did good come from? Why is there good in the world?*
...but rather *If there’s no God, where did good come from? Why is there good in the world?*
He absolutely did addressed this:
“But if, on the other hand, we refuse to accept this conclusion, insisting, for example, that it is always and objectively true that you should love your neighbour and you shouldn’t torture children, we are led away from atheism. The presence within us of an objective moral law ‘written on our hearts’ points instead to the existence of an eternal Goodness and Intelligence which created us and our universe, enables us to think, and is the eternal source of our best and deepest values.”
I think this is his KEY point!
