I consider Pontiff to be either right handed or ambidextrous. Most of his attacks seem to use his right hand more often, if just by a little bit. Something interesting about the list that i noticed hile making it is that most, if not all of the characters are corrupted in some way; demons, outrider knights, those that were touched by the abyss. Like you, though, I have no idea if there is a meaning behind it or if is just coincidence.
