I don't like people who are killed (but this is caused by personal feelings), but in all fairness, what is self-defense? This case belongs to the legitimate defense of the common law system. No legal responsibility! In addition, China's national conditions, belonging to the civil law system, should also belong to self-defense, mainly depending on whether the deceased had fallen at that time and there was no room for counterattack. If it is, it is over-defense! (How to judge, believe in the ability of forensic doctors and criminal police) should be investigated for criminal responsibility according to law! Another said that the murderer was famous again. This is an adult. There is nothing to say. Can't look at the mood. According to the law!
