I'm just wondering how I can be 100% sure that I've narrowed down the right demon?

Thank you very much, I have decided over thought and meditation, that I will become a satanist

Hello, please do not take offense to anything I say or shun me because of my ignorance, I am 16 and I have recently broken away from Christianity. But on the other note, I would like for someone to please help me understand the concept of Satanism, as I have found it can be a very broad subject...
