All negative doing results always negative it never gives a positive outcome.
I knew a person that when he have a spare time he do gambling knowing his limits and just to fulfill his need. Gambling for him is not for a source of income because he knew that it is not a good way to have money, also he have enough money to fund his habit in having fun in gambling especially that it is just for times that he really want to come with his friends.
For this kind of person, it is not wrong. But once you sacrifice something just to fund your bad habits that time occurs that it is wrong.
But isn't burning your money in exchange of some fun is already a sacrificial act? It's bad that he's in that situation, that he feels like he needs to gamble in order to stay sane. Honestly, it's not a necessity to him at all but rather a habit that he got used to. Regardless, it's his money and people have their own ways of burning their money. Others burn their money buying expensive phones, clothes, and designer bags. Others burn their money through gambling. It's not that it's not wrong. It's just not our business. At least we are aware that it's wrong hence we're not going to do the bad things other people do.
How is gambling wrong? I think people who think it is immoral are just of that opinion for religious reasons. It's just like playing a game but with money on the line which can make it exciting, but it's not morally wrong. It's like saying alcohol is wrong. It's not illegal in most places and most people can enjoy it responsibly without it becoming an issue, but on the other hand there are those that can't and it does become an issue for them, but others can enjoy it in moderation and without it becoming an issue or a problem. Same goes for gambling. I gamble once every while, but I can go weeks or even months without doing so, but it's nice to have a 'flutter' as they say every now and again and I think it's just another form of entertainment and something I enjoy. For sure I don't like losing but that's part of the game and something you accept and you should certainly never chase your loses as that's how gambling can become a problem very quick.
I have this new way of looking at addiction. As long as the addicted person isn't interrupting or harming another individual, it's okay. The moment that they steal from someone or take advantage of someone, that's when it becomes wrong. What's legal and what's illegal doesn't determine what's right and wrong. People choose to do those things and they are indeed free to do that. We don't have to mind their business at all. And I think with this new attitude, you get to not care about the world. It saves you from the stress. It's the same reason why I choose to not watch the news as well. Other people's wrongdoings shouldn't be a concern of us unless we are involved.
