Fang Liu understood why the others were angry and unwilling. Even as a doctor, Fang Liu wouldn't want to save a cruel person, which would allow them to do even worse things.
Fang Liu sat down and patiently explained to the two, "Da Bao's condition is not life-threatening, so there's no use cursing him. In other words, he can still live a full life even if he were mute. Do you remember what Old Man Tang told us?"
"He said that Da Bao's temper has worsened ever since he stopped speaking. Old Man Tang even said that Da Bao would go online to watch videos of animals being tortured and killed from time to time."
Old Man Tang thought that it was normal for his grandson to watch videos of animals being tortured and killed, so he told Fang Liu and the others about it without reservations.
Fang Liu continued, "If this goes on, Da Bao's mind will undoubtedly become more corrupted. When that happens, he might even form an antisocial personality."
