The thought occurs to me that if one is going to take readers to task for a certain fascination with the evil characters, then one should perhaps berate Tolkien himself for the same reason. After all, if he could invent such compelling evil characters (instead of just the bare minimum of evil bad guy needed for some conflict), then perhaps he deserves as much censure as those who have readerly interest in those characters. After all, Tolkien very often portrays the "good guys" in a poor light, and occasionally gives reasons to sympathise with utterly abhorrent characters.
Perhaps the professor had a soft spot for evil domination himself. It would probably have solved so many of his problems.
