Satanism is a confidence trick.
Because famous rock bands from the 1960s and 1970s experienced great fame and fortune modern wannabes expect the same thing to happen to them if they sell their souls to the devil.
This gives them confidence.
And this confidence brings success.
They have confidence in Satan - that he can bring them the fame and fortune they crave.
But there is no Satan in reality.
So their house is built on sand.
The success experienced by the rock bands of the 1960s and 1970s was the result of talent and work, not some illusory contract with the devil.
And modern rock bands can experience the same thing.
But it is not the work of the devil.
Entertainers who are popular experience fame and wealth and have devoted fans in any case whether they sell their souls or not.
So Satanism is a confidence trick.
P.S. In the end there is only God's Love.
