I remember clearly when my brother was stuck in gambling addiction, I literally pay for his debt accumulations almost daily so that my parents would not be fully aware of the length he goes in his gambling spree in order to conserve the health of my ageing parents and most importantly my father who has High blood pressure and Sugar problems. It worked at that period, but it cost me a lot of useful money that I would have utilized properly for my own benefits, but I'm grateful it didn't cost me my dad as well.
Gambling addiction affects the person, his finances, reputation and so does it affect his loved ones as well, loans are very bad quite alright because of its high interests, and worse when it's not being used for profitable ventures. The ugliest thing is that the interests keep accumulating and piling up more financial losses for whom it may concern at a later time to save the gambler.
Agree with you, borrowing money to gamble is a mistake because we don't know whether we will win or maybe we will lose, and it is true that if we win it is easy to return it immediately, but if we lose then we will be confused and anxious about how to get the loan money back immediately.
And I really agree with you that if we are addicted to gambling then we might forget to immediately return the loan money because we are already easily tempted by all the types of games that exist and we see it directly and over time then we will definitely object or have difficulty immediately return the loan money.
