In the criminal law, the legitimate behavior based on the promise or voluntary of the obligee is called damage. I don't quite understand this sentence. Ask for guidance

Damage based on the obligee's commitment or voluntary, also known as victim's commitment, means that the legal interests infringed by the actor are some legal interests voluntarily abandoned by the victim before the dangerous behavior is carried out. This kind of commitment can promise many things in principle, but two things are forbidden, even if they are invalid-the right to life and the right to major health.
