’In psychiatry, we do not have diagnostic criteria for a mass murderer, terrorist or violent person. There are psychiatric conditions that may include anger, aggression, impulsivity, violence, or lack of remorse or empathy among their symptoms.

…[O]nly a small percentage of violent acts are committed by the mentally ill, and violent behavior does not have to necessarily be coming from mental illness.
Putting a label on something can only be helpful when we are able to treat it, or when it proves the person is not responsible for the act due to the illness. Furthermore, there could always be coincidence: A person who commits violent acts could have depression, and he or she also could have eczema. But the correlation would not necessarily be causational.…’
