And in my opinion, the step we have to take is to give a small loan only once if he can't and give an agreement that if he can't pay it back as promised then next time he won't be given another loan so that in this way the gambler immediately understands and become aware immediately so you can reduce your gambling addiction slowly.
No, I don't think it's a good idea. Just never grant him any money or loan.
Everyone has their own way of lending money to people who like to gamble. Indeed, I agree with you that lending even small amounts of money will not be good in the end, that person will never stop gambling, lending money to people. Those who gamble are the same as supporting that person's gambling and becoming addicted to gambling, so it's best to avoid people like that who want to borrow money to gamble, even though we are also gamblers, don't let other people borrow our money to gamble too.
There are many cases like that, most people can't stop gambling because their habit is fulfilled. Sometimes when someone doesn't have money, they usually realize slowly that the gambling they are playing has exceeded the limit and makes them bankrupt, aka losing at gambling, if no one lends anyone money. Those who gamble will reduce their gambling slowly and that will help gamblers be more responsible for their gambling addiction and will automatically recover slowly, but if we lend money just to test it, it will be useless and will also be successful in deterring people from borrowing money to gamble.
