Well, the deal certainly seems risky. And his judgement is suspect -- we know he's already risked his life in a stupid way (at least once) to prove his 'intelligence' to Hermione.
But on that occasion, Hermione with her trust in authority pointed out the flaw. Later Harry correctly decided that her advice (or at least, the act of thinking about what she might say) would have saved him from making a big mistake with Azkaban. Since she now appears capable of listening, asking her could yield a net increase in expected value.
I don't even know if Harry made the right decision by protecting her and her friends. We'll see if Quirrell merely increased Harry's reputation or if, thanks to his action in ch. 75, the events of these chapters will ultimately make staying at Hogwarts unsafe. (I'm embarrassed to admit I missed this possibility until I saw an FF.net reviewer make a related point.)

Harry made the right decision by protecting her and her friends. Given what he knows and even given human (and Hogwarts) behavior it gives the best expected outcome.
Yes, Eliezer may construct negative consequences for Harry and try to teach a Deep Lesson but I basically wouldn't buy it[1]. You can't get much better bullying deterrent than seeing them visibly humiliated by first year girls. Add in some naked wall sticking and nobody would want to affiliate ...
Update: Discussion has moved on to a new thread.
The hiatus is over with today's publication of chapter 73, and the previous thread is approaching the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread. This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it.
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: one, two, three, four, five, six, seven. The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.
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:
