Why is the Hated Loved?

[Kuruharan]

What do you think that Tolkien was trying to say?

That human beings are very perverse.

We desperately desire a lot of things that are bad (or, if you prefer, "unhealthy") for us, but we want them anyway.

At the same time we know the damage these things can do to us and are afraid of it and angered by it when the damage is done, but we can't let go.

So we dislike the thing (hate) but we can't free ourselves from it because we still want it (love).
