Here's something I haven't seen mentioned yet in the "McGonagall is
evil" posts: Her name combines the name of the Greek goddess of poetry
-- among other things -- and the surname of the acknowledged worst
poet in the English language, William McGonagall.

Could it be a hint that someone who appears good is actually bad? Or
perhaps she's a little of both. 

William McGonagall's horrible poetry was also thought by some to put a
put on or a satire, though he acted entirely serious about it.
