You can be good for the mere sake of goodness; you cannot be bad for the mere sake of badness. You can do a kind action when you are not feeling kind and when it gives you no pleasure, simply because kindness is right; but no one ever did a cruel action simply because cruelty is wrong - only because cruelty is pleasant or useful to him, In other words, badness cannot succeed even in being bad in the same way in which goodness is good. Goodness is, so to speak, itself: badness is only spoiled goodness. And there must be something good first before it can be spoiled.

C. S. LewisThe Christian and the Materialist hold different beliefs about the universe. They can't both be right. The one who is wrong will act in a way which simply doesn't fit the real universe. Consequently, with the best will in the world, he will be helping his fellow creatures to their destruction.
C. S. LewisGood and evil increase at compound interest. That's why the little decisions we make every day are of infinite importance.
