My friend, a lawyer, replied that if someone threatened me, if I cut him with a weapon, would my responsibility be greater? If the murder weapon is his, I will take him away.

1. If someone threatens you, if the threat is only verbal, and you cut him with a weapon, it is intentional injury, which constitutes the crime of intentional injury and bears criminal responsibility.

2. If the murder weapon is his, if you cut him with his murder weapon, you will intentionally hurt him and bear criminal responsibility; Unless the other party picks up the murder weapon and will hurt you, and you hurt him in the process of self-defense, it can be considered as self-defense.

3, but if your defense exceeds the necessary limit, it is excessive defense, and you still have to bear the corresponding responsibilities.

4. If the other person harasses you and you hurt him with a murder weapon, it is undoubtedly intentional injury and you should bear criminal responsibility.

The best way is to protect your legitimate rights and interests through legal channels.
