2. It must be that the illegal infringement is in progress;
3. Self-defense must be aimed at illegal infringers;

About excessive defense
Excessive defense refers to a criminal act that obviously exceeds the necessary limit and causes great damage and should bear criminal responsibility. The so-called excessive defense refers to the situation that the legitimate defense behavior exceeds the defense scale stipulated by law, so it should bear criminal responsibility. This is of positive significance for encouraging citizens to better exercise their right to defense, protecting their legitimate rights and interests and maintaining social order.
On the crime of negligent death
The crime of causing death by negligence refers to the act that the actor thinks that the death of others can be avoided because he negligently did not foresee or has foreseen it, thus depriving others of their right to life. Article 233 of the Criminal Law whoever negligently causes death shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years; If the circumstances are relatively minor, they shall be sentenced to fixed-term imprisonment of not more than three years. Where there are other provisions in this Law, such provisions shall prevail.
