Satanic commandments, according to
The Church of Satan
1. Do not give opinions or advice unless you are asked.
2. Do not tell your troubles to others unless you are sure they want to hear them.
3. When in another’s lair, show him respect or else do not go there.
4. If a guest in your lair annoys you, treat him cruelly and without mercy.
5. Do not make sexual advances unless you are given the mating signal.
6. Do not take that which does not belong to you unless it is a burden to the other person and he cries out to be relieved.
7. Acknowledge the power of magic if you have employed it successfully to obtain your desires. If you deny the power of magic after having called upon it with success, you will lose all you have obtained.
8. Do not complain about anything to which you need not subject yourself.
9. Do not harm little children.
10. Do not kill non-human animals unless you are attacked or for your food.
11. When walking in open territory, bother no one. If someone bothers you, ask him to stop. If he does not stop, destroy him.
These sound right based on what my friend, who is interested and reads about the CoS, says about it.
I don't so much mind the left and right path or light and dark worker. But to say that left means satanism doesn't set well with me. Diochotemizing these good and bad isn't how I see this. Balance of both appears to be important to holistic approach spirituality, based on how I understand things. The middle way is mine, although I lean to the left side of things and am
left handed duhn dhun dhun! 
, but feel that I can step or blend the right side. Left is just my natural tendency.
So here are a list of the Satanic Commandments. To me Satanism seems to not place importance on Altruism and thinks it's against human nature. I highly disagree with that tenent. Some of the above 11 are still what I'd call 'in line with benefit to society'. There
has to be some ground work of cooperation in any religion amoungst themselves atleast for it to survive, and it appears they are even here as well. A few just cross that line, some might believe.
Hope this adds something. I really didn't know what to say and this is what I came up with, since you seemed interested in what I had to say. Thank you for that.
