Despite how far Cole has come since the beginning of the novel, the way he responds to news of Peter’s suicide suggests that he’s not entirely willing to take responsibility for his actions. As far as he’s concerned, he should be praised for having made as much progress as he has—but Edwin insists that Cole isn’t done until he’s come up with a way to help Peter. Edwin’s unwillingness to listen to Cole’s plan shows that even adults who have learned to manage their anger still struggle. If Edwin is any example, Cole will have to work on this his entire life.
