Why can the former chairman of sunflower pharmaceutical company "kill his wife" be reduced for mental illness?

The first is Guan, the former chairman of Sunflower Pharmaceutical. In this case, although his lawyer claims to be mentally ill, why? A person with limited criminal responsibility? I want to reduce my sentence, but the court did not accept it in the first instance, so it has no explanatory power to this case.

Then let's talk about what is mental illness: mental illness, also known as mental illness, is a disorder of brain function regulation, and its clinical manifestations are different degrees of obstacles in mental activities such as cognition, feeling, will and behavior. In crime, mental illness can be divided into several categories:

One is a complete mental patient. Such a person can neither know himself nor control his behavior. They can't judge whether their actions are in line with common sense, and they have no ability to distinguish good from evil. If their result is a criminal act, they need not bear criminal responsibility.

One is an indirect mental patient, sometimes sober, sometimes irrational and unconscious. If they commit a crime, they must verify whether they were awake or insane at the time of committing the crime. If they are sober, they must bear full criminal responsibility. Whoever commits a crime during his illness shall be given a lighter or mitigated criminal punishment according to the circumstances.

One is that the illness is not serious, but emotional problems do not affect the conscious judgment, and they are independent and have a clear distinction between good and evil. If a crime is committed, it will be tried in accordance with the provisions of the criminal law.

Because after committing a crime, criminal punishment is also used to re-educate criminals, which requires subjective judgment and identification, then mental patients can't do this, so criminal punishment is of little practical significance to them. Of course, for those mental patients with violent tendencies, guardians are needed for monitoring and treatment. If the government can't control them, it can be mandatory.

Finally, I want to say that everyone is equal before life, and the mentally ill have pity, but the injured also deserve pity. We all hope that the law can be more perfect, take care of all events from all angles and give us the best answer.
