1. That's not such a bad idea at all, I like Pippin...but I can't change my name, sorry.
2. "If I can speak from experience, when inventing a character, especially a villain, it is difficult to get one's mind into the right position."
I disagree, look at Alien, he's evil and doesn't change a bit
3. Hmm...I'm not so sure about that Alatar. I don't think Eru really made them pairs, I just think nobody wanted to be together with Melkor. Anyway, I am pretty certain I once say a quote where it read that he had a hidden love for Varda, which would even more justify his hatred for Manwe. What I can't understand is why it necessarily happened to him...
Also, note that the original 14 Valar were 7 Male and 7 Female (somehow it feels wrong to use such terms when talking about spirits), only after the arrival of Tulkas this balance was changed.
