Devil-worshipping Black Sheep Sean "Sellout" Sellers, executed for the murders of his parents and a Circle K clerk, was no real Satanist, who obviously misinterpreted The Satanic Bible and gravitated towards Christianity, where he really belonged.
He could not innately comprehend Satanism, and thus stratified towards a spiritual belief system, not the rational, self-determining, and carnal philosophy of Satanism.
This case is yet another example that adds to the factual dictum "Satanists are born and not made."
