Was Melkor Bipolar?

[Bom Tombadillo]

As someone with a bipolar relative, whose most recent and, hopefully, last episode I got to experience the peak of, I can say that Melkor's behavior does not remind me of someone bipolar. I agree with Galadriel that bipolar people are far more frightening than charming (at least during manic periods - it's just sad when they become depressed ).

Also . . . all right, I'll bite. Where do you get the impression that he is

more interested in sex than most Ainur.

? I for one have not seen anything that would indicate that. Then again, I am just starting my second reading of the Silmarillion and lack some of the familiarity with the subject matter possessed by others here.
