Sure you can. Life is full of trade offs. When the tradeoff is sufficiently in your favor, you rejoice. Sometimes that involves people dying.
That's... more than a little sociopathic. You seem to be saying that the only value of people's lives to you is instrumental: if you benefit from someone's death overall, then their death is a good thing.
if you benefit from X overall, then X is a good thing.
Yes. That's pretty much the definition of consequentialism. Values can be compared and weighed, and when the weight is greater compared to the alternatives, "then X is a good thing".
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.)
