"The worst kind of evil is the wrong kind of love, love that clutches and possesses rather than loosening and liberating. . . . That is Lewis' final statement on evil. Essentially, it is the wrong kind of love. . . . What the evil man calls love is only a sort of hunger aimed at the total consumption of the emotional lives of those around him. What he calls justice is the selfish granting of his own welfare and pleasure, whether on a personal or a universal scale. And what he calls good is that which will benefit his own aims at the expense or despite the needs of those around him. He is evil not because he wills to be an evil man but because he can do nothing else but will his own narrow desires."
