Characters in As I Lay Dying
From the paper:
Self-interest is what drives the characters in this novel, and self-interest is what destroys them as moral human beings. This aspect is what turned this story into a tragedy. There is a decent level of intellect within the minds of certain characters, but they are still nothing more and nothing less than a poor, southern, white trash family. That is all they will ever be, for their own selfishness and arrogance is what keeps them from evolving as human beings.
