As Walter tells of his plan to do business with Lindner, what does Walter claim to have learned from his experience with Willy Harris? How does Walter seem to have changed? Act 3

Walter claims to have learned that people are dishonest, and he is tired of people taking advantage of him. He tells his mother that no one else is worried about whether or not they are doing the right thing or the wrong thing..... so why should he. Walter seems to have become embittered by his experiences.
