Let me ask you a question. If you went to your dad, and told him that you hated him and never wanted to see him again ever, what would he do? He would be hurt, yes, and for a time even try to regain the relationship. But after his years of efforts to rekindle a relationship with you, you still keep sending him away. Finally, he says, ok, this is what you want. You don’t want a relationship with me. I will respect your wishes, and I will not be near you again.
This is not a perfect analogy, but in a way, this is how it is with us and God. He gives us chance after chance, but if we keep sending Him away, that we want nothing to do with Him, he will honor our decision. And that is what Hell is. The absence of God. I think at that point the flames or anything else that may or may not be there will be inconsequential. What makes Hell, Hell, is the absolute absence of God that was a deliberate choice of whoever is there.
As for the OP - it is not healthy to indulge in a constant preoccupation with the occult. Not to say that we should bury our heads in the sand, figuratively speaking, but I have read many of your other threads, and it is a little concerning. The occult is a lot more dangerous than, sadly, many Christians realize. The best thing is to immerse yourself in good solid Catholic and Biblical teachings and books. If you do decide to pursue study of Christian Demonology as you call it, may I suggest consulting with a knowledgeable priest to oversee your study and to assist you in prayer and act as your “safety line” lest you stray too far - or to decide if such study is even appropriate or not for you at this point in your spiritual journey.
