That's an opinion. Thing is that your only mean to prove anything right now is using outside factors. That's hardly conclusive as you can just pull any number of mythological/LoTR reference and say that their meaning are definitive even in Zelda, yet they might only make sense to you.
Why do you keep going back to the LotR reference, which I only used as a readily-available comparison and has absolutely nothing to do with my current argument? What I'm talking about are Japanese cultural elements that the developers have built into the game's plot, and which most, if not all, Japanese players would be able to recognise. I'm not talking about my personal opinions or interpretations, I'm talking about facts equivalent to reading a direct Japanese translation.
And do not dare to accuse me of lying. I've built a reputation over three years by being completely honest and abhorrent of people who twist the evidence to suit their own ends. The worst you can accuse me of is making mistakes. But I am not wrong this time; the "thief" identity was inherant to the human Ganondorf and was destroyed with the character's rebirth into Ganon.
