Why does mental illness not have to bear legal responsibility?

Because mental patients have no normal knowledge of external things, their actions are not intentional, do not meet the constitutive requirements of crime, do not have the ability of criminal responsibility, and do not need to bear criminal responsibility. Intermittent mental patients who commit crimes when they are mentally normal should bear criminal responsibility. Intermittent mental patients who commit crimes when they are mentally normal should bear criminal responsibility. If a mental patient who has not completely lost the ability to identify or control his own behavior commits a crime, he shall bear criminal responsibility, but he may be given a lighter or mitigated punishment.

Not that mental patients can't be sentenced. It's that mental patients can't identify or control their own behavior, resulting in harmful results. Those who have been confirmed by legal procedures shall not bear criminal responsibility, but their family members or guardians shall be ordered to take strict care and medical treatment. When necessary, the government forces medical treatment. If you are mentally ill, but you can't identify or control your behavior when you commit a crime, you can still be investigated for criminal responsibility. For example, intermittent mental illness, usually committing crimes. But without criminal responsibility, we must bear civil liability, such as compensation for losses. If the mental patient himself has no property or has insufficient property, the guardian needs to bear the responsibility.

Mental illness crimes are not criminally responsible because mental illness belongs to the behavior of people with no or limited capacity for civil conduct when they are sick. Not all mental illness crimes are not criminally responsible. Only after the harmful results caused by mental patients who can't identify or control their own behavior are identified and confirmed by legal procedures can they be exempted from criminal responsibility.
