I do not think gambling is wrong, it is wrong when people expect to always win
Sometimes greed is take over people's mind. We can see people keep stubborn eventhough if gambling is bad for them and for their family
Don't think there's really a wrong or right answer here.
It really depends on how you use your money with gambling.
For me, better to keep it ( low risk , moderate profit ) rather than gamble it ( high risk , high profit )
