Nah, gambling isn't wrong as long as you don't gamble excessively. It becomes wrong when you gamble all that you have even the money that you should use to buy food. When you can't control yourself not to gamble specially when your losing. You should understand just gamble what you can afford to lose.
Well gambling never be wrong, it only depends on greediness of people who playing that.
You maybe right at this point, but once greediness comes in into your mind I think that could be wrong anyway. ans to tell you the truth, in the sight of many gambling is really wrong that according to them.
