What means that a person's trial will not include the same elements if they suffer from a mental illness? Mental illness opens the door to the complexities of the human brain and how it works. Without a good understanding of the brain, we cannot understand disease. It's not something anyone can control, and without diagnosis and treatment, people won't get better. Furthermore, if a jury only knows the name of a mental illness and not its symptoms and cause, then they really have very little understanding of it and the trial will continue despite their ignorance on the subject. Sixteen percent of inmates in state and federal prisons suffer from serious mental illnesses such as schizophrenia or manic depression (Mohlman, D.M. (2005). The Value and Importance of Treating Mental Illness - The Costs of forgetting mental illness). Psychopaths have the emotional IQ of a 5 year old (Smith, RJ (2015). Forget Furman) and a 5 year old would never face the death penalty for crimes of emotional insufficiency. A person with mental illness should be treated and rehabilitated, not sentenced to death
