I wonder what they actually mean by “exterminations” in this show. I don’t think that Alastor is telling the whole truth about the full extent punishment in hell. Plus, Charlie’s partner/girlfriend talks about being erased in one point in the first episode. It really makes me wonder…
What I’m pointing at is like in some teachings of Christianity, Judaism, Zoroastrianism, and the tenets of the Ancient Egyptian religion, the soul can literally die and end up obliterated/fade into oblivion (In the case of the Ancient Egyptian afterlife, those that reach the domain of Osiris and fail the weighing test get eaten up by a large beast). In other words, if your soul goes through enough damage, you completely cease to exist aka ERASED from existence permanently; no feelings no consciousness no senses at all, nothing but complete darkness with no sound, sight or other senses. And just because Angel Dust said “face it you’re stuck with me” doesn’t automatically invalidate my point. He very well could be ignorant about the part about being erased.
