I'm not so much concerned with the reasoning around the duel (apart from why AK was needed to make someone dodge). I'm mainly against Quirrell taking the boy to Azkaban in the first place. General common sense says that is not a good idea unless it is a desperate situation. Especially since Quirrell can't cast magic on Harry if he decides to do something rash.
What is the expected utility of taking Harry to Azkaban in total, from Quirrells point of view?

I don't know his numbers, but something like (Bellatrix's life - risk of failing and both dying). Given that he had the perfect plan, is maybe the most powerful wizard around, and had Harry along to beat the Dementors, the risk of failing was probably lower than half, which means the expected utility is positive.
- This thread has run its course. You will find newer threads in the discussion section.
Another discussion thread - the fourth - has reached the (arbitrary?) 500 comments threshold, so it's time for a new thread for Eliezer Yudkowsky's widely-praised Harry Potter fanfic.
Most of the paratext and fan-made resources are listed on Mr. LessWrong's author page. There is also AdeleneDawner's collection of most of the previously-published Author's Notes.
Older threads: one, two, three, four. By tag.
Newer threads are in the Discussion section, starting from Part 6.
Spoiler policy as suggested by Unnamed and approved by Eliezer, me, and at least three other upmodders:
It would also be quite sensible and welcome to continue the practice of declaring at the top of your post which chapters you are about to discuss, especially for newly-published ones, so that people who haven't yet seen them can stop reading in time.
