Why should we remain innocent of what lurks in the shadows? How can we live in the world if we don't understand how dark and brutal it can be?

It's not evil, Rand. I know something evil when I smell it. This isn't evil, it's just incredibly stupid.

For My people are foolish, They know Me not; They are stupid children And have no understanding. They are shrewd to do evil, But to do good they do not know.

Encouraging virtue is better than suppressing vice.

An apparent misfortune of man is that neither good nor evil is an agency itself; both are equally passive choices. Man himself is the ultimate agency. He has the power to realize and activate the dead options. Only then, that is, by the action of Will, good results in good and evil in evil.

To be wicked is never excusable, but there is some merit in knowing that you are; the most irreparable of vices is to do evil from stupidity.
