Frustration can make people do things they never planned to do. From the story, the guy lost his life savings to gambling and that is why he is championing the campaign against gambling. The reality is that he was a gambling addict who obviously went about gambling the wrong way. One is not supposed to use his entire fortune in gambling knowing that it is a game of risk. Instead, gambling is supposed to be done with passive income and not regarded as a full time job. His action is totally unneccesary, well anything for content is not fine as that is the world we now find ourselves in. But I don't think he will be able to discourage people who understand and abide by the basic rules of gambling.
I think frustration is one of the things that can happen and be experienced by gamblers when they gamble excessively, such as being addicted to gambling because if they are addicted to gambling it can make them do things that are not normal, and if they feel annoyed there is a possibility they are at the point of frustration because they have risked everything they have to pursue victory, but if they don't get victory even though they have risked everything they have, they can experience frustration which can ultimately have an impact on their own mental health.
It's true what you said, they shouldn't use all their wealth or money just to gamble, because in my opinion that will only make the host rich. with the fact that gambling will only end in defeat, not victory, therefore we must be aware that gambling must be done with full control and good awareness so as not to do it excessively. realize that gambling is a game of chance and gambling is something that carries a big risk if we do it too much.
I myself advise my friends who have recently been gambling by giving examples of the bad effects that have occurred because of those who are addicted to gambling. because I myself don't want my friend's life to be ruined because of his gambling addiction.
