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.

Quotes from the same author

My parents were lenient. My mother believed God was another word for nature. I took up Satanism not out of desperation, but out of logic. I rebelled, not but because of a religious or repressive childhood. I wanted to join the French Foreign Legion.
In order to perform the supernatural, you must first be able to accomplish the supernormal.
Life is the great indulgence - death the great abstinence. Therefore, make the most of life here and now!
Satanism encourages its followers to indulge in their natural desires. Only by doing so can you be a completely satisfied person with no frustrations which can be harmful to yourself and others around you. Therefore, the most simplified description of the Satanic belief is: indulgence instead of abstinence.
Satan represents indulgence, instead of abstinence! Satan represents vital existence, instead of spiritual pipe dreams! Satan represents undefiled wisdom, instead of hypocritical self-deceit! Satan represents all of the so-called sins, as they all lead to physical, mental, or emotional gratification!
