I have involved myself in this in the past when I was taking a personal study on how people behave when they gamble and what propels their stake. I noticed that those who win are happy and those who lose are easily triggered to violence. Sometimes, those winning increase their stake and those losing reduce their stake and tries to pick safer games to stay longer gambling. When he wins he forgets about all his misfortune. Gamblers don`t keep note of their losses when they win.
On that day, I got myself masked in different feelings. When someone wins I have wished I was the one and the expenses the money would have covered for me. Is that greed? To me, no. We all want good things to happen to us and wishing for fortune is not greed. Also, those unfortunate gamblers I felt pity for them and saw most of them as irrational with the thought that they shouldn`t have gambled with such an amount. It was then I realized that the only reason people frown at gambling is because of losing. If you always win people will wish to be you but can you always win? No, this is why no matter how I felt that day I never envied anyone because you might win today but what happens tomorrow?
Well, that doesn't really need a lot of education and research regards to how people would be. We are talking about one person winning money versus one person losing money, obviously it is going to be quite different results. The violence part is just offline version, these online casinos are fine because they are not really located at any shop, they do not have a casino that you can go to, hence there will not be a violence, they can annoy or troll online if they want to but that's about it, they can't really do much else.
I think it is clear that we are not going to see too many people have too many different results all that easily. This is why I believe that we need to just consider the possibility of it later on some other time.
