Some people believe in the end do gambling will lead you to something wrong.
And some people think gambling itself is a wrong thing to do.
So if the context about gambling are wrong overall, I guess yeah gambling are wrong. Too many bad effect caused of gamble rather than positive thing.

your argument pretty makes sense, we may spend money too much and lost money that we can't afford to lose and it makes our assumption to do gamble are wrong at all.
always be like that, when we found ourselves in win phase we will call gamble are right thing! but when lost we usually call gamble are wrong thing to do isn't it?

How about if we treat gambling of way to have fun and source of income? Many people are doing this thing right but sometimes they are too greedy so lose many but still they are feeling so fun to gamble like this. So I think there is no way that gambling is wrong in every perspective

Some were born to be lucky, some not. But not all those lucky people always become rich by gambling.

We can't blame on "gamble" , the only could be blamed is your self.
Why you choose to gamble ? Why you start being greedy ? So I guess gamble is not wrong , your self that choose to do gamble and lost every time is the only problem that make gamble wrong.

treating gambling as source of fun is fine but treating it as a source of income was a bit wrong imo. that will just lead to someone being greedy. and we all know how greed will always end up

Indeed. I had a lot of fun when I gamble and somehow I find that all the numbers entertained me. Well, if I won something, that is extremely fun for me too.

I know for some people gambling cant be source of income because they cant control when they are holding too much of money. But for me I dont think that is something wrong because if you can manage to control yourself and manage your income and outcome why bother about being greedy or not? You will know when to stop although your greediness is coming up

Yes, that is true. But there is still some people who managed to become a millionaire by gambling.

Indeed. But, IIRC, there is this one guy (Archie Karas, IIRC) who turned $50 into $40 millions!
Eventually he still lose it all. :-(
