Exiled Master Jedi
I would normally agree with you, but good and evil is just not that simple. Ganondorf returning as the King of Evil isn't really worth anything, nor did it tell us anything other than that he got a longer, less catchy title.
I would like to know how the amount of evil is a pointless factor though. On what you are basing this. There is one thing dealing with an evil man, but something entirely different when you're dealing with the embodiment of all evil that exist.
From what I've seen, and I'm going to talk Pokemon tongue now, the Master Sword is Super-Effective against Evil, but Super-Effective could still lose battles. Yes, that's a metaphor. My point is, Gorribal is like nothing Link or the Master Sword has ever encountered. The Master Sword is used to minions of darkness, but Gorribal is PURE evil. There are no factors of significance, nothing of importance beyond the fact that all evil that exist is Gorribal.
