Hmm, I don't know that I subscribe to that. I think Inchoroi really are damned. I think they really are souled. Because what gives the soul is, in a sense, language and self-consciousness. Sranc, on the other hand, or bashrags and the like, are conscious in a sense, have language, but they do not have the ability, for whatever reason to grasp the Dasein of spirit, that is, to Be in a way to which the question of Being has meaning. In other words, Sranc have no ability (desire?) to question the Meaning of Being. Therefor no soul.
This is always why some "unsouled" things can gain a soul. If it gains some sort of language by which to form the question and can identify itself, as a self, then it can have a soul, so it can be damned. Because at that point, it can question the nature of Being, it can ask and interrogate sorts of Is/Ought distinctions, it can modify it's behavior and isn't just what Bakker might call "a meat machine." Therefor it bears something like what we'd call Identity, it bears something like what we would call Responsibility. That is the Dasein of Spirit, sort of, the Being of a Soul.
