I use to have an interest in the Occult and from my research this so called Satanism it was just an extreme form of atheism which seemed more interested in pissing people off than being an actual religion.
A lot of the so called rituals were actually just developed as a mockery of Christianity. Goats instead of sheep, Drinking blood as oppose to kosor diet, inverted cross, etc etc.
Come to think of it, the JW memorial to Christ seems like a satanic ceremony.
