Gambling is not wrong, but the wrong person when playing on it. In my story, I have been playing but too emotionally and uncontrollably, and then busted. Gambling can be mastered if we always control ourselves and try to make strategy in every play. gambling is not wrong, that's depends at playing on it i guess.
It is, in my opinion, people who play and gamble that seem greedy and materialistic and the person get easily angry, that's someone who shouldn't play. Knowing that gambling could lead you to destruction in the bank and probably with your relationship with your loved ones. That's just epic, you should know your limits.
