 * Deep Breath* Ok! No half demons or demons allowed until there is one in the canon. Period. Even with DFs their race/species wouldn't change to half demon, since no Zoan is considered to be two species.

As for good vs. evil... I really don't think there should be any spiritual powers, other than haki, at all. This is not Bleach, Inuyasha, Yu Yu Hakusho or any other anime/manga. The only powers or abilities in One Piece are haki or Devil Fruits. To be honest I'm not even keen on having DFs that give off demonic or holy auras, since they really don't have a place here seeing as there are no spiritual powers. So, ultimately, there is no "good and evil" to be considered. Holy objects can be "holy" but they can't really hold any power, unless they consumed a Devil Fruit.
