Well, ++ for effort, but your proposed names would need some reconsideration. Problem is that "unbeliever" and "infidel" are synonyms; as are "offender", "sinner", and "transgressor"; as are "heretic" and "blasphemer". "Fallen" refers to pretty much everybody.
I would propose a taxonomy with fewer levels. How about
Level | Title |
-1 | Benighted |
-2 | Sinner |
-3 | Excommunicant |
-4 | Witch |
-4 | Troll |
Hmmmm... A Possible down-side to this whole idea is that it gives persons of a certain anti-social inclination something to strive for. In effect, it rewards undesirable behavior.
Maybe what we need is something like:
Level | Title |
-1 | Penitent |
-2 | Excommunicant |
