ACT TWO: Pages 69-70: Fully explain the moral conflict between Joe and Chris Keller. How does it constitute the theme of the entire play?

The conflict between the two men is directly related to Joe's business. Chris is uncomfortable with the success his father's business found during the war, when so many of his comrades died pointlessly. He redirects his discomfort into an idealism and an attitude of social awareness that is foreign to his family environment.
