"Understanding the cause for Bartleby's reason to be an introvert and to offer polite refusals when asked to do something would suggest he deserves either sympathy or disdain."

I need to reword the whole thesis using different words but meaning the same thing. I am having a hard time doing that.

Recognizing the cause of Bartleby's introversion determines the readers' reaction.

To comprehend why Bartleby tends to be introverted and consistently provides polite refusals when tasked with something, determining whether he warrants sympathy or contempt becomes imperative.
