Women vs. desire of the ring

I just looked up Beruthiel. (Gosh, why did Tarannon ever hook up with her?) If I read the note in Unfinished Tales correctly, Beruthiel might be Tolkien's nod to the Wicked Queen archetype. He was wise enough to know that all of anything on earth is either good or bad, so we have a "bad" female.

You know, as I was looking her up, I bet myself she had to be the wife of a human king. I just couldn't picture an elf or other non-human female really wanting the Ring. Even Ungoliant & Shelob were beyond such things!
