Consider sacrifice and empathy. The Captain is the second of Eddie's "Five People." He was Eddie's commanding officer during World War II and was taken prisoner in the Phillippines and along with Eddie and four other soldiers. The Captain comes from three generations of military men and had taken a vow to never leave a man behind. He confesses to Eddie that he was the one who fired the shot into Eddie's knee, thus causing the injury that plagued Eddie all his life. However, the Captain also reveals that he died shortly thereafter - he stepped on a landmine while trying to get the injured Eddie to safety. The Captain therefore teaches Eddie about the importance of sacrifice: he shot Eddie in the leg so that Eddie would not die in the burning tent. Even though the Captain ended up sacrificing his life for Eddie's, he was able to keep his promise to not leave anyone behind.
