I find your impressions of good and evil rather amusing. Grindelwald is basically a utilitarian, something that most people are, he just doesn't do it very well. Slughorn was specifically introduced to be a good guy Slytherin, if a bit weaselly, so I disagree with you there as well. And Percy's a tool, but he's not actually evil, he's mostly just self-important and clueless - ditto Lockhart, for that matter. It's nowhere near as morally arguable as MoR, but it's hardly a world of cardboard either.
Re Vanishing, that's a fair point. But to counter - what do the kids get told about where the cats go? Regardless of the truth of the matter, if they're told "Oh, we just bring them back after class", then they'll be fine with it.

Lockhart mindwiped a bunch of people to steal credit for their good deeds. He ended up attempting to mindwipe Harry and Ron. He's evil.
The next discussion thread is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
