The attitudes of the Keller family range from denial and guilt to hope and a desire to move on. Let's take a look at each of the Keller family members in more detail.
Joe Keller: The main conflict of the drama All My Sons is the role that Joe Keller played in the death of his own son and many other young men fighting in the war by knowingly selling defective plane parts. The different attitudes of the various members of the Keller family to this is shown by the characters throughout the play. Until the very climax of the play, for instance, Joe Keller refuses to take responsibility for his actions and acknowledge his wrongdoing. Once he does, however, he cannot live with himself, particularly knowing how his actions contributed to his own son’s death.
Kate Keller: Joe’s wife, Kate, refuses to acknowledge the reality of the family’s situation. Kate refuses to accept the likelihood that Larry is dead and continues to cling to the hope that he is missing in action and will return one day. Larry’s tree in the Keller backyard is representative of Kate’s hope of this.
Chris Keller: Chris Keller, the Kellers’ son, recognizes that his brother is gone and wants to move on with his own life. He has fallen in love with Ann, Larry’s former girlfriend, and he would like to marry Ann, even though his mother opposes this relationship because she unrealistically holds out hope that Larry and Ann will one day be reunited. Ann condemns her father, who was Joe’s business partner, for his role in the sale of defective parts.
