I really don't like when gamblers are characterized it's mean to do it. What happened with him is not due to gambling it's because of his problem with his wife. This drew him to gambling, and it's bad that gambling he lost 4 million. I don't think gamblers end up like this, cause he wasn't addicted, all he needed a distraction and gambling gave him one. In his obsession he lost his way, he needs counselling that's all. And some miracle to pay his debt.
I think he is not mentally good that is why he did like this. But this is common in gambling there are many examples of this kind of addiction. People why take this gambling to make money I don't understand. Everyone knows the after effect of gambling, but still, they become greedy. We can not stop this kind of people. They will not listen to any person suggestion. Finally there end will be worst like this.
