Are you a better person?

[Imladris]

Am I improved, or ‘more’ than I was before I read them? And if so, is the effect cumulative – do I get “better” the more attention I pay to this story?

I wouldn't say that LotR has made anyone "better" per say. Maybe made them aware of such things as nobility and honour and truth, but, in the end, it's up to them to act upon their newfound discovery. But I believe I am merely nitpicking...

As for getting "better" every time I read LotR, I don't really think that is possible. A book can only give so much.
