they will become dangerous because they can do almost anything only to get some money so that they can continue gambling, and that isn't a good thing for those who live around them, they can do kidnapping, robbery, stealing, or anything that can provide them some money to the time being.
If someone is addicted to gambling I don’t really have issues with that as long as you are having money with you will continue to waste on gambling, but when the main problem always comes in is when they are no longer having anything to gamble with, they will end up doing illegal things, they will end up hurting people around them and people in the society, just to get money to gamble with, that’s why in most societies, people see gambling as a bad thing, they don’t care if you are addicted or not, if you tell them you are a gambler, or they discover that you are a gambler, they will stop associating themselves with you, because they will see you as a bad influence and all is being caused by people that are really addicted to gambling.
So, an addicted gambler doesn't basically stop when they get out of money
When a gambler stop gambling when they get out of money, I won’t really call that a addicted gambler, but the set of people that I do call addicted gamblers are the once which will do crazy things just because they needed money to gamble with.
