I could go to town on your whole post but this final line of yours really spells it out for me. Lucifer truly is your brother from another mother (and I bet you'd take pride in that if it was actually true).
Such a logical leap of absurdity is one I'm thankfully unable to make as, I have posited, to "understand" the demon/devil may well be to become it/him. Thus, by the grace of the almighty, I am literally incapable of parsing your "logic" as it were.
Oh I can, in a hypothetical sense, but not in that "visceral" sense I made mention to in my relevant responses. I can "understand" Satan in a sense, but I cannot ever truly "get" Satan if ya catch my meaning. Can you truly "get" the likes of me? An ILI who is fervently religious? Who sees the deniers of Christ as hopelessly misguided at best and demonically obsessed/possessed at worst? Can you even cross yourself if even mockingly? I am curious. After all, my faith is only rivaled in fervency by my bottomless desire for hard data relevant to my many and myriad hypothesis regarding the truths of this reality
