Gambling can change the attitude of someone who tends to become a stubborn person, and indeed this can of course have an impact on their relationships, whether it be family, partner or friendship relationships, where they will experience the bad effects of gambling, which can make them change as well.
Can gambling actually change someone who is bad mannered for good instead of getting them more complicated in their wrong doings, same way we can see gambling as a means of getting ourselves attached to something that could get us being occupied than having much time on unnecessary things, we should also be mindful of not allowing irresponsible gambling to affect our personal relationships.
For me that don't think that we have alot of positive change coming from gambling at some point and this is because, the outcome of gambling is just either for the fun or entertainment, and if gambling is taking to be a such of income that means that, we are going to experience alot of the negativities that comes along with excesive or uncontrollable gambling, and in essence this could affect our overall well being and also making us to feel or act in negative ways and manners that could affects our total well being at some point.
So if you ask me whether or not gambling affects someone attitude the answer will always be a yes since if you involved yourself so much on irresponsible gambling, it Will have such effects on you outward character also
I also think like that, I think those who gamble will only experience changes in things that are negative, because many gamblers experience negative things, such as addiction and also their finances become unstable because of gambling, maybe only a few people experience changes positive because of gambling, but in my opinion almost no one experiences changes in a positive direction because of gambling.
For someone who gambles, of course they have to gamble responsibly, because many gamblers are irresponsible because their actions make them addicted to gambling. Those who have gambled have certainly experienced a lot of losses and that is because they are not responsible. If they could be responsible, maybe they would not have experienced a lot of losses, because many people gamble excessively, there are no limits to gambling, which makes them himself became addicted to gambling and experienced many losses. and it's true what you said if they involve themselves too much with gambling, it can make it more difficult for them to stop gambling.
