Could you help me rephrase this sentence?

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

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

How about --

"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."
