‘Miller’s characters tend to deceive themselves about reality.' How far do you agree with this comment?

Theme of Denial and Self-Deception:

How do we deceive ourselves and others? We select things to focus on in life, but do we also need to deny certain things in order to live well? What toll does denial take on the psyche, the family, and society? Two main facts about the Keller family history must be confronted. One is Larry's death, and the other is Keller's responsibility for the shipment of defective parts. Mother denies the first while accepting the second, and Keller accepts the first while denying the second. The result is that both characters live in a state of self-deception, willfully ignoring one of the truths so that the family can continue to function in acceptable ways.
