Most weapons deemed inhumane are the sort of thing that would be about as unpleasant as being tortured to death. The de facto ban on poison gas in WW2, for example - if I had to choose between mustard gas and napalm, I'm not sure which way I'd go. For that matter, plenty of people are burned alive in ordinary wars(naval combat is particularly bad for that, along with the aforementioned napalm), and that's never been deemed worse than any other death in any legal sense.
Also, all we know is that she was burned to death. Ordinary fire deaths are not the sort of torture you're suggesting - they're relatively quick in most cases(minutes, and not many of them), so 2) in particular doesn't apply strongly.
The new discussion thread (part 15) 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 82. The previous thread passed 1000 comments as of the time of this writing, and so has long passed 500. Comment in the 13th thread until you read chapter 82.
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.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
