Only people who are addicted to gambling will have a bad influence on their environment and themselves, so someone who has an addiction tends to be detrimental, therefore most of the society and norms do not like gambling because it can indeed have a bad influence on someone who is already a gambling addict, we may not have to blame the platform but in this case they also contribute because they provide a place for people to gamble, But this is complex because gambling has many meanings for its fans, first a place of entertainment and second a field for making money, and it is the second option that makes a person bad, because in some gambling advertisements say, win money with a certain nominal, yes maybe some stupid people will consider it an opportunity for them.
It is not surprising that many gamblers see the bad effects of addiction on other people around them, because if they become addicted, bad effects will occur and this can have an impact on their own environment such as family or friends as well as relatives. and this is the reason some people are not happy with gambling because, as you said, it can have a bad influence on someone and even more so on other people who don't know anything about it. People who are addicted to gambling tend to get emotional easily, when they lose they won't be able to accept their defeat. There will definitely be a feeling of wanting to gamble again, and when this happens, for example, someone tries to prevent them from betting again, whether it's family or friends, well, the person who prevents it This can hit the target of the addict's emotions.
I think that those who become addicted and experience serious negative effects are because they gamble with the aim of making money, not for fun. because with those who gamble for fun, I don't think they will experience addiction because maybe they have more self-control and strict boundaries so they don't gamble excessively or beyond their own abilities. with those who are addicted to gambling, they are trapped by the lure of advertisements that are widely spread.
