This is too much, kidnapping your own daughter is really too much, well they wont call as addicts if they would not do something terrible, the addiction of gambling is really high nowadays, they will really do something just to have money and to continue on gambling, specially if they had lost their money in gambling, they will really do things to earn money even just to hurt one of their family's or doing such things like what that old man have done to his grandaughter.
Gambling addiction is really a big problem in a community, we should alwas keep our mind good and dont let gambling control our mind to do terrible things, if we lose then we should accept it, there's no need to do bad things to have money and to continue playing again, we can still play in some other days if we already have money, do not sacrifice yourself identity just to gamble.
