Society has some rules that in the long run has proven correct.They,the society see gambling as a bad thing and not necessarily gamblers as bad persons but since these people called gamblers are involved in this bad act then most probably they assume these people to be bad.History has shown us that except those people who won multi million dollars jackpots no one else has been successful in the long run in gambling,this says a lot as why gambling is considered bad by many religions and societies.In gambling you can never earn continuously as no one can control their emotions for a long time without making a rushing bad decision.
What makes gambling illegal is the impact the gambling process has on it. The negative impact often occurs when you lose and continue to lose, the capital you have runs out and eventually you will commit criminal acts in order to get capital to gamble again. But for those who gamble just for entertainment, their money management is of course very minimal and doesn't care about winning, only as entertainment. emotional control is indeed very difficult, an addicted gambler will not be able to do it. Playing gambling must be with a clear mind and the purpose of gambling must also be clear. do not cross the pre-defined limit. if you win stop for a moment, if you continue to lose stop and leave first.
