It is easier said than done. I cannot say that we can totally excuse and keep gambling away because addiction does not come to a person out of nowhere.
True but we can always try to be safe and not addicted in gambling, we are the only one will manage ourselves, we can't blame others but ourselves if we make mistakes.
It is the gambling itself that made the person addicted.
No, it is his gambling style that makes him addicted, blaming gambling generally is just like not accepting your mistakes, blame yourself first.
That's being responsible and able to accept your mistake/s.
