What does Cole's feelings about the thought of his own death in chapter 12 tell you about him?

Cole suddenly sees the world as a wonderful place. He wonders how much beauty he has destroyed and how much he has missed by seeing only the ugly side of everything. He feels himself slipping closer to death and knows he won't survive much longer. He is glad that he had the moment of trust with the Spirit Bear before facing death. This tells us that Cole has finally changed: he becomes a dynamic character.
