Articles 22 and 126 of the 2015 Criminal Code stipulate:
Article 22. Justifiable force
1. Justifiable force in self-defense means the a person's use of force which is reasonably necessary to defend against another person's infringement upon his/her legitimate rights or interests of himself/herself, other people, the State, organizations.
The use of justifiable force does not constitute a criminal offence.
2. Unjustified force in self-defense means the use of force which is more than reasonably necessary and not appropriate for the nature and danger to society posed by the infringement.
The person who uses unjustified force in self-defense shall take criminal responsibility as prescribed by this document.
Article 126. Involuntary manslaughter because of the use of unjustified force in self-defense or while capturing a criminal
1. An involuntary manslaughter because of the use of unjustified force in self-defense or while capturing a criminal carries a penalty of up to 02 years' community sentence or 03 - 24 months' imprisonment.
2. The involuntary manslaughter of 02 or more people in this case carries a penalty of 02 - 05 years' imprisonment
Therefore, when it is deemed that the level of resistance is appropriate, it can be considered as a legitimate defense, fighting back more than necessary is considered to be beyond the limit of legitimate defense. If someone else hits him first, he will fight back to cause death, but he is still not considered in the above two cases and is still charged with murder as usual.
For example, in the following two judgments:

In conclusion, if we can be beaten by someone for no reason or for some purpose, we must also be alert to have a suitable countermeasure if we do not want to be entangled in the labour cycle.
