The family didn't do anything bad, even though they went too far in it. They were trying to protect themselves and their brother, who's an addicted gambler.
However, there has been a topic that quote A Nigerian Father Rejects Son's Gambling Win, so it is not the first and this can not be the last of it.
Family might not be perfect but we do know on whats the best for us, gambling isnt bad but on the time that they've been seeing that you are really that getting addicted too much because they've obviously see you
that become impulsive into your actions like selling your possession or things just for the sake of gambling then this is a solid indicative sign that you are really that addicted to it.
It might really be that looking too much for some people but for me it is really just that right. Doing things for the sake of someones safety or trying out to stop on whats the worst things could happen
will be always be the wise thing to be done in the first place. I wont really be feeling bad about it if i were that boy who had been addicted, you would really be able to
appreciate on what are the things that they've been doing just for your own sake and safety or trying out to avoid the worst things as possible.
