I don't think that you and kilobug are actually in contradiction. Kilobug is saying that the deaths of the Death Eaters is a negative term in the utility function. You are saying that the total utility of the act that kills them is positive (or greater than the alternatives). Unfortunately, idiomatic English discusses these two very different points in similar language.
In other words: kilobug says that, as you survey the consequences of Harry's act of transfiguration, when you get to these deaths, you do not rejoice; buybuydandavis says that, considering all of the consequences of Harry's act of transfiguration, you rejoice. At least, that's how I understand you two.
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 117.
Plans for next chapter release:
There is 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.)
