I believe that you should not lend money to people who are addicted to gambling and alcohol, as you are not helping them, but supporting their addiction. In my opinion, it is much more productive to educate them about the harm of their addictions. Addiction is a kind of disease that can be very difficult to cope with, especially for people who have a psychological predisposition to it. If we help such people, we should only help them with full confidence that the money will not be used to support their addiction.
However, the only problem is if we aren’t aware that this person is into gambling and just think of another excuse that would convince us to offer money or lend money for him. We are pushing him to his gambling addiction unconsciously. But if in the first place he’s known to be a gambler, why lend him money? That would only make him believe that it’s easy to sustain his gambling addiction since the people around him are even supportive of his wrong doing.
Well that's true, that's also what's on my mind, because after all we never know about the habits of other people and also usually gamblers who borrow money are often dishonest or mean not telling the truth to the borrower and say that the money is for other urgent needs in their lives, to be honest I really know about this because previously my friends and I often borrowed money with that reason when I was still trapped in addiction.
Basically it's difficult to really know whether the person is involved in gambling or not, especially if they are not too close to us, therapy of course if for example we know about those who are involved in gambling then it is clear that lending money to them is a big mistake even though they say that the money is not to finance their gambling activities, but on the other hand I think lending money to them does not mean we support their addiction if for example from the start we don't know that they are gamblers.
