It does include the secondary effects of their deaths acting as a deterrent.
But I don't share your view that deontology allows for more credible precommitment to punishment, except in the somewhat trivial sense that such a precommitment is more credible to observers who consider deontological precommitments more credible than consequentialist ones.
That is, a commitment to punishment based on an adequate understanding of the consequences of punishment is no less likely to lead to punishment than a commitment to punishment based on deontological rules, and therefore a predicter ought to be no less likely to predict punishment from a committed consequentialist than a committed deontologist. Of course, predicters in the real world don't always predict as they ought, so it's possible that a real-world predictor might consider my commitment less credible if it's expressed consequentially.
It's also possible they might consider it more so. Or that they might consider it more credible if I wear a red silk robe when I make it. Or any number of things.
It's valuable to know what factors will make a claim of precommitment credible to my audience (whether I precommit or not), but that doesn't make deontology any more valuable than red robes.
NOTE: As pointed out here, my use of "precommitment" here is potentially misleading. What I'm talking about is an assertion A that I will do X in the future, made in such a way that the existence of A (or, rather, the existence of other things that derive from A having existed in the past, such as memories of A or written records of A or what have you) creates benefits for actually doing X in the future (or, equivalently, costs to not doing so) that can outweigh the costs of doing X (not considering A).
Once you add TDT to consequentialism, the differences between it and intelligent deontology are pretty trivial.
The new thread, discussion 13, is here.
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. With three chapters recently the previous thread has very quickly reached 1000 comments. The latest chapter as of 25th March 2012 is Ch 80.
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: one, two, three, four, five, six, seven, eight, nine, ten, eleven.
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:
