Harvey’s father Christopher Dent was an alcoholic, as well as abusive. This could have been the start of Harvey’s disease, this is because most people who develop Dissociative Identity Disorder were subjected to major psychological or physical trauma as children. Harvey wanted to help others like him so at the age of 26 he became the city of Gotham’s youngest district attorney. In the early movie Harvey is late to a major trial but he shows his hubris and strolls in like nothing happened, and then is unphased by the attempt on his life made by the testifying member of the Falcone family, he stands in the line of fire and once the pistol fails he punches and disarms the man and has a snappy one liner to say how he should have “bought american”.
