Captain America Comics #72

A psychoanalyst cures one of Cap's apprehended criminals of his tendency to commit unlawful acts by using hypnosis to enter his mind. He discovers that the man stole a broach of his mother's as a child to have something of hers near him after the birth of his little brother and when she found out about it, she slapped him and told him that he would probably become a criminal. Once the subconscious memory has been brought to consciousness, the man loses his desire for criminal activity.
