interesting to note - he's only referred to as such in the third person; he refers to himself as Ganondorf, which is a notable thing considering his characterization in the game
I believe that the distinction between Ganondorf, the man, and Ganon, the monster, is not only important, but perhaps even indicative of a more distinct separation than has been made clear... which seems likely enough to come to a head in BotW, the game where Ganon is immediately apparent as less than a specific being but more as some kind of evil force
in fact if you've played Skyward Sword to completion this should all seem pretty believable considering what happens at the end of that game
