Never. If you are stupid enough to gamble at that point, you deserve to bankrupt yourself. Money that you earn easily is also spent and wasted easily. An infinite money glitch would be a jackpot on steroids. You would not care so much if you should spend it on something or not. Combine this with gambling where money is lost fast and emotions are high, and you have a recipe for disaster. Instead of helping people in need, you would be losing thousands or even hundreds of thousands depending on how much your glitch is generating. You don't even feel good from this gambling, but you continue to do it and lose money.
It is actually very true that people easily spend money that is earned easily. And when a gambler loses money, he becomes aggressive and at some point he loses control over himself and becomes addicted to gambling. Gambling is more about how the gambler controls himself than it is about where the money comes from. When a person loses control of himself, he cannot think of helping others because then he is lost in another world.
You can see this easy with lottery winners as the best examples, but it also happens with relatively smaller wins in casinos. I've seen people win $200k at slots and waste it even if it was a big amount of money to them. I've also seen people win $200k and then continue to bet it hoping for a bigger score only to lose it all again fast. It is a very dangerous combination, easy money and a place where it is easily spent or wasted.
