A 18-year-old boy stabbed his sister about 2 cm in the head with a screwdriver. What is the statutory punishment?

Is it your own sister? If it is your biological sister, her guardian, that is, her parents and she have no intention of suing or asking the boy to bear legal responsibility, and an understanding has been reached, it will be fine. Just educate them. Boys should have a good mentality and a sense of repentance. Aside from this, my sister is not sensible and can't do this to her. After all, she is her own family. She should know something when she is eighteen, right? I hope that through this matter, he can reflect on himself.
