There is no 'sin' in Spiritual Satanism. The concept is only in the Poo people's religion and its illegitimate bastard religions. Yes, as a gentile, you are expected to have your head on the shoulders, some brains in your head, and not be insane like Joos/Poos, Pisstians and Mudslimes, going around raping, murdering or doing some other shit in the name of religion. Being an SS is also about being a responsible human being when you are alive in this world. There is nothing called 'morality' as such. It is a human construct. What may be moral for you may not be moral for someone else. For a thief, stealing maybe his livelihood and hence, moral. But for someone else, it maybe immoral. Same with rape and murder.
Of course, no sane person would do any of this willfully. Even if you are talking about justice, murder or rape is not necessarily the right way (having said that, retaliation and black magic for the purpose of protecting self and serving justice is necessary, but you have better ways than raping or murdering someone. You can pretty much destroy someone without committing these 'sins').
Regarding consequences of committing a sin, you will get caught and punished if you commit any of these. However, spiritually speaking, every action has a karma attached to it, whether good or bad. Of course, it does not mean that you will be roasted in hell's fire as what Xianity, Pislam or any corrupt religion teaches. But your karma will follow to your next life, as a life lesson that needs to be learned. It most probably would be a bad situation though, which will whack you on your arse and teach you the lesson in a hard way. There is a detailed sermon about Karma in the newsletter. You can go through that.
Hail Satan!! Hail Enki!!
