Wrong or not, people keep gambling. If there is still a maze between right and wrong then treat gambling as our respective views. If we think gambling is wrong, then do not ever gamble, if we do not think gambling is wrong, then gamble if you want. It all starts from the self, no need to judge.
People have the freedom on what to do, we have different belief in gambling, some would say it's wrong while others believe it's just
an entertainment so losing would not be an issue as a real entertainment you are oblige to spend money to enjoy.
As long as you stay on budget, gambling can always be appreciated.
