The truly sad thing about them is that they think by honoring and worshiping Satan they might position themselves in his favor when they die and go to hell believing he is going to be in charge there. On the contrary, Satan is going to be the MOST punished and tormented and, rather than his followers receiving preferred treatment, they will also be doomed for eternity - much to Satan's delight for he hates ALL of mankind.
I cannot fathom why someone would choose hell when we are given every opportunity to take heaven since God has done everything needed to get us there and offers it to us as a free gift.
