On the topic of morality, I'll just leave these C.S. Lewis quotes here:
“If we ask: ‘Why ought I to be unselfish?’ and you reply ‘Because it is good for society,’ we may then ask, ‘Why should I care what’s good for society except when it happens to pay me personally?’ and then you will have to say, ‘Because you ought to be unselfish’—which simply brings us back to where we started.”
“If the whole universe has no meaning, we should never have found out that it has no meaning: just as, if there were no light in the universe and therefore no creatures with eyes, we should never know it was dark. Dark would be a word without meaning.”
- C.S. Lewis
