"I killed someone."
The youth was detained.
His name is Bei Jiao, he is 27 years old, working in a research institute, and is a young scientist. The deceased's name was Jia Beihai, Bei Luo's colleague and roommate.
According to Bei Luo, the two had a fierce dispute at work, which ended in a fight. Bei Luo hit Jia Beihai in the temple with an iron bar, and Jia Beihai died on the spot.
"But if I don't kill him, I will die. I have no choice."
You can only kill the person who kills you if you know you are going to die.
Intention: When the victim becomes the perpetrator, how should his crime be written?
