Whatever you guys decide, good luck. May the odds be in your favour 
I don't think there is any wrong or right in this, just pure luck and maybe a slice of strategy.
It's only wrong if you're placing yourself in a lot of debts
Gambling can be fun but it can also be very wrong as you touched upon. Many people who gamble regularly end up becoming addicted and that is just a waste of life as the gambler will be forever chasing losses and falling further in the hole.
OP it is not beneficial to anyone except the casino owner and the few that only play to have fun and gamble within their means.
The same as everything in life, moderation is the key and don't expect to win lol.
Yes it can be fun but only if you're winning. That's the feeling I get with gambling at least. It's only fun when I'm winning but when I start to lose I take a second to redeem myself and if I still have some money left over from the money I set out to gamble with I'll continue after that, if not I quit for he day.
