My interpretation of this topic has literally inverted due to certain analyses and comparisons of content in
Skyward Sword and reviewing of elements in previous titles. Now, while I do not believe Demise placed a literal curse, something struck me quite a while back, and the pieces began falling into place. I am talking about Nintendo re-working aspects of religion into the series.
So, this certain analogy wasn't the first in the series of them, but for the sake of this post, it would make most sense to mention first. The story of Adam and Eve—it is technically a parable, I know. But, a while back, I began viewing the Triforce as the fruit of the Tree of Knowledge. Its existence was the cause of imbalance of good and bad, and its shrine Eden—the Sacred Realm—envelops it. Anyways, there are obviously twists in this, as Demise is, in essence, Hyrule's embodiment of the devil. At least, that's what his role would be when looked at in this perspective.
Now, to Demise's so-called "curse"… I am amongst those of you who doubt there is an actual curse. But, if Demise is equivalent to the malevolence of the devil, then his "hatred" is fundamentally like Original Sin. And the temptation is what could essentially be what he was referring to when he said his hatred would never be extinguished. There would always be someone weak of heart to succumb to the temptation to seize the Golden Power—just as Eve did the fruit of knowledge.

One of his character flaws. I don't think he necessarily had been evil if the Triforce was in existence; however, I also still hold the belief that Kotake and Koume had some role in his diversion, therefore he may have still ended up with twisted beliefs and a lust for power—just not in the same manner he had gone about it.
Hyrule's philosophy has been backed with religion before. It has been done in the past. Other than the fact that the notion of deities is present, little things that allude towards it—especially toward Christianity. Take this piece of official artwork from
A Link to the Past for example:

But, a recapitulation: if Demise's intentions of the "curse" was truly his hatred acting as a way of temptation, then it does not explain Ganon's existence—just his actions. The Triforce was the driving force behind his aspirations that warped his mind. Just like how the serpent in the fable "tempted" Eve to take a bite of the fruit—he was very likely "tempted" to take the Triforce as he lacked the judgment to resist. And as they said God put the Tree of Knowledge in Eden as a test, the Golden Goddesses perhaps left the Triforce behind for the same reason.
But, that's just one way to interpret it. My onion.
