You're correct, but I was responding to the whole statement:
I wouldn't want to rule out the possibility that Dumbledore deemed himself indispensable >and his soul's contiguousness dispensable to the war effort.
If our dear Headmaster murdered Narcissa because he thought his continued availability to Magical Britain was more important than avoiding that kind of atrocity, or keeping his soul whole then that means that he used the murder to protect himself from death, and in this context that means that he made a Horcrux.
This is, of course, all conjecture. We don't know for certain that Dumbledore himself did the deed, or that it went down the way that the surviving Malfoys believe it did. We do know that Dumbledore finds it useful for them to believe it, and we do know that he has studied how horcruxes are made as part of his Anti-Voldemort campaign, and we can be fairly sure that Madame Bones knows the truth of the matter of Narcissa's death
Evidence in favor: Dumbledore thinks it's plausible that he's the Dark Lord from the prophecy, which would require it possible to destroy all but a remnant of him.
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 85. The previous thread has long passed 500 comments. Comment in the 15th thread until you read chapter 85.
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, 15.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
