Thank you. Yes, my question was about the moral difference, not the technical one, as other replies seem to interpret it. I understand that Harry had to have precautions in case his transfiguration fails at some point, but still, he destroyed the identity of his mentor without an immediate need to do so. He could have delayed irreversible actions until he has time to reflect. Rather un-Harry-like at this point in the story. Unless I'm missing something.
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 118.
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.)
