Seek help from a lawyer: a person with limited criminal responsibility intentionally kills.

A person with limited criminal responsibility? According to what you said, one is that the victim is slightly injured, and the other is that the suspect is a person with limited capacity. On the whole, he should bear criminal responsibility. But probation can be applied completely. Article 234 of the Criminal Law of People's Republic of China (PRC) shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance. (This clause applies to the situation you mentioned first. Under normal circumstances, people under the age of three can suspend classes at the same time. )

Whoever commits the crime mentioned in the preceding paragraph and causes serious injuries shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years; Whoever causes death or serious disability by particularly cruel means shall be sentenced to fixed-term imprisonment of not less than 10 years, life imprisonment or death. Where there are other provisions in this Law, such provisions shall prevail.

Paragraph 3 of Article 18 of the Criminal Law stipulates: "A mental patient who has not completely lost or controlled his capacity for behavior shall bear criminal responsibility for committing a crime, but he may be given a lighter or mitigated punishment." Mental patients with limited criminal responsibility are some mental patients between the first two types of mental patients. Compared with mental patients without criminal responsibility, such people have not completely lost the ability to identify and control their own behavior, so they cannot be completely exempted from criminal responsibility like mental patients without criminal responsibility. But as a mental patient, this kind of person's criminal responsibility ability has weakened after all. Therefore, China's criminal law stipulates that such people can be given a lighter or mitigated punishment.
