Many, many people worship Satan without ever considering their actions as such worship. As an Authority on the subject once said to some such,
“You are of your father, the devil (diabolos = slanderer, false accuser), and the lusts of your father you will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaks a lie, he speaks of his own: for he is a liar, and the father of lies.”
Just sayin’. . .
