"Pleasure, money, power, and safety are all, as far as they go, good things. The badness consists in pursuit of them by the wrong method, or in the wrong way, or too much. I do not mean, of course, that the people who do this are not desperately wicked. I do mean that wickedness, when you examine it, turns out to be the pursuit of some good in the wrong way. You can be good for the mere sake of goodness: you cannot be bad for the mere sake of badness. […] Goodness is, so to speak, itself: badness is only spoiled goodness. And there must be something good before it can be spoiled."
- C.S. Lewis (Mere Christianity)
