What I want to see is the update about this and how was the boy reacted and and what is the movement he comes out.
Because I believe that if the boy made to gamble all those times meaning His father did not look into what is he dealing and yeah that means they allow him to gamble but does not want to win?
If I were to be the boy? surely I will leave the house and will live my own .
The boy is addicted to gambling maybe his father doesn't know about it but when the boy wins the gambling and gets money profit then maybe the boy's father comes to know about it and makes him pay back the gambling money. In this case, the boy's father had religious feelings behind not taking the gambling money and the boy decided to return the gambling money based on that religious feeling. In this case, the boy did not disobey his father and he was forced to obey his father's orders completely.
