Article 20 of the Criminal Law stipulates that in order to protect the state, public interests, personal, property and other rights of oneself or others from ongoing illegal infringement, stopping illegal infringement and causing damage to the illegal infringer, it belongs to self-defense and does not bear criminal responsibility.

If justifiable defense obviously exceeds the necessary limit and causes great damage, criminal responsibility shall be borne, but the punishment shall be mitigated or exempted.

Taking defensive actions against violent crimes such as assault, murder, robbery, rape, kidnapping, etc., which seriously endanger personal safety, and causing casualties to illegal infringers, is not excessive defense and does not bear criminal responsibility.
