I think there's no wrong on gambling the one who gamble and gamble over and over again even if he didn't benefit from that's the real wrong and besides gambling can be dated long ago we should know the history of it.
According to me, it is not exactly wrong it is rather a useless act. However, it can be wrong in some scenarios too. For instance, if a gambler gambles more than he should that is gambling with unlimited amount of money and time. I am also in not favor of gambling with debts. Hurting anyone by any means is indeed wrong in my dictionary.
I don't see it as a useless act rather a riskier way to earn money fast where there a high risk of losing but a there's a chance of earning a high amount of money.
And yes, gambling isn't wrong but you can use it in a wrong way from which you get addicted and gamble money that you didn't even have. But that's not the only way you can use gambling since you can do for fun and earn money by just betting those extra money you had.
Oh wow, if you think that way then I have no problem with you sticking to it. I won't stop anyone from dying if he is that willing and blind. Dude, lets just face the facts. Check out the stories of those who have committed suicide and willing to. How about jumping into a wall of fire and making a video, upload it, you will earn money (if you make alive out of it), believe me its a lot riskier.
