Who is The Conscientious Objector from The Great Divorce and what is their importance?

Many of the characters choose to be left out of the holy bright procession because they cannot shed their earthly pain and vices: they are archetypes of personalities in our world that are addicted to their burdens. The Conscientious Objector feels that the world is against him. He feels an obligation to protest "incorrect" policies and philosophies. And in objecting governments and people he has removed himself from his country and eventually from all his loved ones. Even after his suicide, he still cannot be happy. He finds himself still objecting to everything around him and does not have the humility necessary to realize that he is the one who needs to change.
