There is no reason to expect that any of his hints are anything other than deliberate lies.
Quirrell certainly talks about the need to act exactly as the person you're impersonating would act. His speech to Hermione would be no evidence at all if it were delivered by someone who practised what Quirrell preaches.
But that isn't Quirrell. Far from putting up a perfect facade, Quirrell's mask is constantly slipping. He "makes a game of lying with truths, playing with words to conceal his meanings in plain sight." His dialogue is peppered with hints to his identity, his past, and his intentions. Almost everything he says about himself is a clue.
His love of the killing curse and his intent to kill. His childhood ambition to become a Dark Lord. The Muggle dojo. The Pioneer plaque. His intention to crush Rita Skeeter. Repeated use of the word 'Riddle'. His willingness to be identified as having eaten 'death'. His wish for Britain to grow strong under a strong leader. The story of Merope's enslavement of Tom Riddle Sr. His theft of Quirrell's body using incredibly dark magic.
I think you've confused the actual character of Quirrell with the master of deception that he claims to be. When he tells Hermione about the time he spent as a hero, that is evidence that what he's relating is a twisted version of the truth. Because it usually is.
Incidentally, while I was collecting links, I discovered that Quirrell foreshadowed this after all.
"It has sometimes amused me to play the part of a hero. Who knows but that You-Know-Who would say the same."
I read this as his saying Voldemort has previously played the part of a hero. And, as above, I think it's probably true. What's your take?
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.
