In my point of view, there is nothing wrong in gambling.  It is just a game that needs a wager to be able to win a stake.  All the decisions, actions, emotions, psychological breakdown, addictions, are people's doing.  Gambling is just  gambling, why will it be wrong.  If a person play in moderation it can help relieve stress and tension.  And be able to refresh people.  It is the  uncontrolled action of people that is wrong and not gambling.
