Its differ from everyone's perspective. For me, it's not wrong for gambling because I treated gambling is a very risky investment. You place money to get more money not very different from nowadays investment, but very risky win big lose big.
I don't understand this what the wrong way is in gambling? And what is the right way in gambling? According to me, Gambling is just game. How you treat gambling is the matter. If you play this for money, then it is wrong. But if you play gambling just for fun or entertainment then it is ok. Finally playing or not it depends on you.
The reality is it depends on the outcome of our gambling every time we do it, if we win in gambling the we will say that gambling is right and when we lose we say gambling is wrong. Gamblers are just unfair as we just want to experience the winning side.
