If looking for the wrong one is indeed the culprit, namely the gambler, he is responsible for whatever decisions he makes, even with controlling his emotions, finances and other ha there is no one who can help him except himself, including his behavior towards the people around him.
Ha like this should be realized by the perpetrators of gambling, but unfortunately people who are addicted to excess they turn a deaf ear and ignore anything and that's the reason why addicts will be claimed as a bad influence on society, people like this must come to the point where he can't do anything else and realize that he must make changes in his life to live better.
This is key, right now whenever a person does something that is considered to be out of the norm, explanations are trying to be given to the behavior they are showing, in an attempt to try to switch the blame away from the individual, but this has the problem that it teaches people that nothing is really their fault and instead their parents, friends or society are at fault for their problems, when in fact the most likely cause for your problems is yourself, and if you cannot accept that then you will never overcome them.
