It's just confusing enough to work to everybody's advantage, the scoundrel and the righteous. Conscience once had an objective meaning. You know-the Ten Commandments. There's a time lag between the rejection of God and the rejection of objective morality. Besides, my conscience is telling me things don't look as bad as they did yesterday, and that what I felt was criminal last week is not such a big deal after all.
Conscience needs to be educated.
