Really sad to see people get eaten by gambling and making a lot of wrong decisions in life, Suppose it might connect to being a man taking all of their problems by themself, I mean if he tells this problem to his family I really doubt that this is still going to happen When men tend to hide their problems they just solve it by them self and starting to make wrong decisions, but if their share their problem it could help a lot and his family can easily help him solved his dept, whatever it is they are still family so they'll help each other.
Still difficult to think that people can go this far, to the point of doing something to their own granddaughter I mean I see all grandmothers and grandfathers as loving people maybe because they are already old they just think of taking care of their family because they still can.
So far I noticed a lot of people who are not able to control themselves because their desires dominate their minds more than their own logic, and that also happened to that grandfather (in the first post of the OP)
gambling addiction is one of the most dangerous things in society, I'm sure the government in every country really pays attention to this because it can be an order of social life in society, hopefully bad events like this topic only happen once in a lifetime
