i'm a satanist after laVey too and I'm halfway through the satanic bible. Most of its ideology is about commen respect that goes bothways and about always doubting stuff (cause thats how you grow in yourself as a person). Satan ain't no ceature whoyou should obey, satan is a symbol of selftrust. For Example: If you want to achieve something, take care of it instead of praying and hoping; its in your own hands.
Hope this helps:)
