Perfect Characters

During the Box Hill outing, Emma and her friends are playing word games, the way they do (consciously or unconsciously) so often in this book.  Mr. Weston proposes a "conundrum":

"....What two letters of the alphabet are there, that express perfection?"

    "What two letters! express perfection! I am sure I do not know."

    "Ah! you will never guess. You," (to Emma), "I am certain, will never guess. I will tell you. M. and A. Em-ma. Do you understand?"

    Understanding and gratification came together....

Mr. Weston's riddle, though "a very indifferent piece of wit," is of a piece with the riddles and cyphers that characterize this novel.  But the theme of this riddle--perfection--is also everywhere.  "Perfection" is the criterion by which characters in Emma are judged: Emma is or is not the perfect character, depending on whom you ask (Mr. Woodhouse? Mrs. Weston? Mr. Knightley? Emma herself?).  Harriet thinks various men are "all perfection." Mrs. Weston, similarly, is perfect in Emma's eyes.  Almost an inverse of P&P, Emma thus frames misreading as an act of seeing perfection, and corrected reading as the ability to see another's flaws.  My question has to do with how we resolve this aspect of the novel with the "bildungsroman" aspect of Austen we've been exploring: do you think the final "moral" message of Emma is merely to become aware of one's flaws?  Or to try to rectify them?
