I will definitely feel pity and bad for them but they know what is right for them and what is wrong so they should go ahead with what makes them feel good and better. But this situation can only be possible to someone or people who are addicted into gambling because why will someone in his normal state be gambling and be using more than what they earns, it is really an error and it has to be corrected but such situations it is only God that can help such person because it is a difficult situation to handle ordinarily and I don't believe advise will even work at this point.
Well funny enough, greed can make a normal person display sch act of stupidity. On a Quest to make some quick money, greed can push someone into taking actions they'll regret later. Some gamblers when they look at their potential wins, they'll already imagine such an amount in their account, and some will even increase the amount l, forgetting the potential risks of losing all the money. Such risk is just out of this world
