Addiction in gambling is really hard to get rid of it most of the time your temper is more attractive to any gambling once your a gambler you will die a gambler and you can't change that tho the greedisness to earn back what you've already lose chasing after your lose will be result as your become poorer and get nothing at the end untill you will lose your mind thinking where you gonna get money for your self.
I disagree, for me its a case to case basis. Other's who really sink below of gambling addiction have already recovered and didn't get the faith of the killer. So we should generalized that "once a gambler, you will die a gambler". This guy went overboard and no one to talk about his addiction that's why he did what he think is the right way. But I believed that if he got the support in time, he won't commit this crime.
