Every character represents a very real facet of human nature, good or bad.

Kutuzov, for me, represents the sort of man whose good deeds, hard work, and brilliance go unnoticed because he is not flashy, does not play politics, and just does what is required of him. In a way he is the most tragic because he is, though officially honored, unrecognized.

A lot of us can feel like that many times in our lives.
