To the family, its gonna be harder to forgive the old man kidnapping his own blood to satisfy his addiction. The man disregards everyone in the family but himself.
Asians have different culture which they have a strong family bond and they respect the elders. But this is too much. This might not be his first offense so there could be petty crime he did in the past too which his family had ignored.
No, I mean why didn't the family prevent it before everything happened. Before that event happened I thought some strange behavior would be shown. Gambling addiction is also something that the family should remind and continue to advise. And when something like this happens, who is to blame? old man turned into a monster by his addiction? I don't think so, because he clearly can't control himself anymore, and it is the duty of those closest to him to be able to pay attention to his behavior.
