What happens if he just bolts and tries to use the Time-Turner as soon as possible? He gets shot, obviously, or at least shot at; but wizards seem hard to kill by mundane means, bullet wounds usually aren't immediately fatal, and fast-moving targets in close quarters are hard to hit. I think he has a good chance of survival, maybe better than if he does what the legendary dark wizard wants.
On the other hand, if future Harry suddenly appeared, Time-Turned, in the forbidden corridor with serious wounds from Muggle weapons, I can't see that doing anything other than causing a massive stink. The fact that present him and the rest of the students got to the forbidden corridor without encountering a stink may count as evidence that it wouldn't work.
Two new short chapters! Since the next one is coming tomorrow and we know it'll be short, let's use one thread for both.
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 105 (and chapter 106, once it comes out tomorrow). EDIT: based on Alsadius' comment about thread creation for MOR chapters, let's also use this thread for chapter 107 (and future chapters until this nears 500 comments) unless someone objects to doing so. Given that this is the final arc we're talking about, thread titles should be updated to indicate chapters covered.
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.)
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:
