You seem to be saying that the only value of people's lives to you is instrumental
I think you're misreading the comment -- it only says that a human life does not have infinite value and that worthwhile tradeoffs where part of the cost is someone's death exist.
I'm not convinced. I agree that worthwhile tradeoffs where part of the cost is someone's death exist, but the way that's framed in the comment suggests that people dying is irrelevant to whether one rejoices over a worthwhile tradeoff or not. This contrasts heavily with, say, Harry's view, which is that a necessary death is still a tragedy.
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.)
