Please don't borrow and spend on gambling, it might give an earning, but that mostly leads to suffering. 
I still remember this being discussed in one thread in the gambling section about things gambling players shouldn't do.. starting from don't get drunk when gambling, don't bring family problems, work, or love when gambling and last don't borrow money to gamble.. borrowing other people's money to gamble sounds very easy if you win but in reality, it will lead you to other bigger problems if you lose.Indeed, you are lucky if you got no interest on your borrowed money or else you can see your debt growing because you will be unable to pay it until the interest is much larger than the debt itself. I have seen several people who borrowed money to gamble and have their life miserable because of that one error. Another one had his house confiscated by bank due to unpaid loan and had his house as collateral.
Gambling is real evil. It is so addictive and deceiving that the gambler keeps on losing but still comes back to lose more. It probably kills his all senses and makes him desperate. Moreover, it is not shocking to know that losing money makes people crazy and that too continuously. Things really become worst when gamblers borrow money and lose that too. It is best to never play this game.
I think not, it is due to a persons lack of self control. Gambling is there and never forces you to indulge on it. It is our own personal decision that we gamble and whatever the consequence is, it is our own fault not the gambling itself.
