When a Satanist commits a wrong, he realizes that is it natural to make a mistake―and if he is truly sorry about what he has done, he will learn from it and take care not to do the same thing again. If he is not honestly sorry about what he has done, and knows he will do the same thing over and over, he has no business confessing and asking forgiveness in the first place.

— Anton Szandor LaVey, The Satanic Bible

“Satanism advocates practicing a modified form of the Golden Rule. Our interpretation of this rule is: “Do unto others as they do unto you”; because if you “Do unto others as you would have them do unto you,” and they, in turn, treat you badly, it goes against human nature to continue to treat them with consideration. You should do unto others as you would have them do unto you, but if your courtesy is not returned, they should be treated with the wrath they deserve.”
