It’s simply incredible how you could go so far in your addiction as to borrow three hundred thousand dollars from different people and spend it all on gambling! I think this problem with addiction takes a long time to form and he is a very long-time gambler, or has an unstable psyche, which makes his self-control weak. And of course, to these factors you can add great greed and the desire to get rich quickly.
That will happen to those who addicted to gambling. He can do many ways to have money to gambling. We never think that he will use that way and spend it all on gambling.
His self control is weak and can not prevents himself from not gambling and not trying to stay away from gambling because he is too far in gambling. He never see what is happening to him instead still gambling without think he has the problem and don't search for how to solve his gambling addiction.
He tempts of what he see from gambling and thinks that he can gets the money by playing gambling games. But he doesn't see that gambling can even takes his money immediately and makes him addicted to gambling.
