Yes, I am sure that what you said is true, which is addiction that triggers various aggressive actions such as borrowing money or even other crazier actions such as stealing or robbing, and of course they are definitely irresponsible gamblers and this is usually caused by gamblers who from the start misunderstood what and how gambling really is, most likely they are too tempted by the name of victory or the chance of victory that makes them interested in getting involved in gambling.
Some general advice that is often said by others such as gambling with the amount of money you can afford to lose, we can actually conclude that gambling is recommended to be done with mature self-preparation to face defeat, and when it turns out that you force yourself to gamble with the funds borrowed, it means that you can conclude that you have deviated from various advice that leads to prevention.
I agree that a gambler's lack of understanding and preparation often leads to making irrational choices such as borrowing money just to continue gambling out of greed for winning big.
Only those with a clear mindset and strict boundaries should gamble because if these are not maintained, it’s better to completely avoid gambling to prevent falling into a cycle of debt and regret.
Yes, it's actually that simple to find out what causes someone to become addicted or what causes someone to dare to do various aggressive actions, one of which is borrowing money, and I'm sure that the action was taken because they were already in despair, as we know that borrowing money is an action that is generally done when we are not able to solve problems related to money and when a gambler borrows money just to realize his gambling desires, then it can be interpreted that they are forcing the situation and of course that is the wrong action.
As you said that only those who have a clear mindset are allowed to gamble, that means gambling must be done with great care and also the right perspective regarding what and how gambling actually is because it is very difficult to cure someone after they are trapped in addiction.
