Right off the bat, I'll tell you that 'Satanism' is a loaded term with various interpretations. This podcast episode specifically focuses on the Church of Satan, founded by Anton LaVey.
Founded on April 30, 1966 c.e. by Anton Szandor LaVey, we are the first above-ground organization in history openly dedicated to the acceptance of Man’s true nature—that of a carnal beast, living in a cosmos that is indifferent to our existence. To us, Satan is the symbol that best suits the nature of we who are carnal by birth—people who feel no battles raging between our thoughts and feelings, we who do not embrace the concept of a soul imprisoned in a body. He represents pride, liberty, and individualism—qualities often defined as Evil by those who worship external deities, who feel there is a war between their minds and emotions.
In other words, Satan is a concept rather than an actual being and does not represent evil, as they argue that pride, liberty and individualism are not negative things.
However, the book of Proverbs says that pride comes before the fall:
Pride goeth before destruction and an haughty spirit before a fall.
