The first rule that I think is fair to peoples is that “If a son strike his father, his hands shall be hewn off”. It is because why would anyone wanted to hit his/her own daddy, they made so many sacrifice for your family and you wanted to strike him, he can strike you, but you can’t strike him because he’s your father. Your hand should be cut off so that you wont strike your father or parent again.
The other one I think is fair is “If a free-born man strike the body of another free-born man or equal rank, he shall pay one gold mina”, because you have to pay the money for the victim to go to get hospitalized or something like, its similar to the law we had right now, if you injured a person inappropriately, then you have to pay the medical money.
