I think it can be accurately stipulated that no person voluntarily does evil on a sustained basis who understands the alternative at an emotional and spiritual level.
The people who do evil no doubt rationalize it somehow–perhaps something as simple as “I enjoy it”, but they see no good alternative.
My standing claim is that Goodness is by far the most interesting, most fascinating, most creative game in town. Everything else is repetition, and in most cases compulsive repetition. As I have said, quantitative variation is obviously possible, but reimagining the self and the world in new colors and with new music is not.
Evil is the despair of the blind.
