How does a father adjust his mentality when he hits his daughter?

As the saying goes, the tiger alone doesn't eat the child. A biological father like this, beating up his daughter is the work of a psychopath or an inhuman person. I want to say here that he is not even as good as an animal, and he is not worthy to be a man or a father at all. If you want him to adjust his mentality, reasoning with him is like casting pearls before swine, because he doesn't know how to reason. One way, like a robber, is to fight violence with violence and let him know what it is like to abuse his daughter. It was not until he understood from his heart where the truth came from that he was convinced and rational.
