I suggest that Voldemort was intentionally turning Harry into a Horcrux.
For the central premise on which your theory is founded, you skip over this without giving any reason to privilege this possibility over others (such as "Voldemort wasn't intentionally turning Harry into a Horcrux"). It's hard to take a theory seriously when it skips straight from a central premise to discussing implications, without considering the state of the evidence first.
As an example problem, all other Horcruxes, both in canon and MoR, are nigh-indestructible magical artefacts. In fact, the only other MoR one was chosen for its utter inaccessibility to Voldemort's enemies. Yet here Voldemort is choosing a baby as guarantor of his immortality.
If Harry contains a copy of Voldemort, then acquiring political power for Harry is, in some sense, acquiring power for Voldemort.
Again, needs justification. If Harry is a Horcrux, this has not given Voldemort any form of control over him (not even the canon mind-link). Acquiring power for Harry only acquires power for Voldemort if Voldemort can control or manipulate Harry - and this he must accomplish without any aid of Harry's Horcrucicity.
But if he really does want Harry in power, why remove his friends?
In order to forestall their positive influence on his personality and make him more open to his own cynical worldview, and thus his manipulation.
Also, two "l"s in "Quirrell".
Another reason to remove Harry's friends is to get rid of anyone that might be suspicious if Voldemort were to take Harry's place through possession or Polyjuice. Compare this to Noble Hero's behavior after returning from Albania: he avoids family and former friends, presumably to avoid being identified as Voldemort.
The next discussion thread 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 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
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, 14.
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:
