Satan thinks that by their sins shall ye know them

My Master strongly urges His followers to disbelieve any claim that any god makes about itself, its religion, or its followers. And while He is at it, He also urges His followers to disbelieve any claims the gods make about each other, their religions, or their followers. They all take credit for human behavior that would otherwise have wiped the species from the face of the planet had not humans figured it out entirely on their own already, and they all blame each other—but more often my Master—when their ill-wrought plans invariably go haywire.

There is one exception to the above: the gods make the religious equivalent to a Freudian slip when, observing their followers, they declare certain types of human conduct to be sins and respond with ordinances and statutes intended to prevent their followers from committing them.

Sins are the dirty laundry aired in full view. Unlike other religious gobbledygook the sins were not invented; no, says the Devil, what became sin is what the followers actually did to an excessive degree. Sins are the warning label that Satan thinks His own followers be wise to read and remember when they encounter a follower of his enemies’. If it is a Buddhism sin to possess an ego, expect your average Buddhist to be egoistic above average. If Christianity views adultery as a sin, keep an eye on your daughter if she mingles with conscientious Christians. If Allah forbids his Muslim followers to feel pride, know that a Muslim will respond especially hostilely when insulted. Jehova identified an impressive array of punishable mistakes made by his desert people that makes one realize that their managing to feed and to procreate without genetic starvation must have involved the help of friendly neighboring tribes. Satan has no specific recommendations regarding the Jews, who realize that faced with such a wealth of options for sinning, sinning is an inevitable part of life and thus the Jews seem less prone to being subconsciously obsessed with actually trying.

Religions evolve along with Society, though, and Satan cautions that millennia-old sins should be taken with a grain of salt and be trusted somewhat losely. The Devil thinks that His followers should grant the followers of old religions some benefit of doubt if they seem moderate in their beliefs. Conversely, the lists of sins of younger religions are perfectly up to date. If the Devil heard of a religion established within the last century or two which had identified traits such as stupidity, counter-productive pride, self-deceit, etc. as its sins, He might like the religion but would conclude that its followers were mostly a sorry bunch of self-inflated, juvenile know-nothings.
