I think some people will still try to playing gambling even if they know the positive and negative side of gambling games. Some of them can control themselves in gambling because their purpose is not for making money. But for some other people, they become addicting because they cannot control themselves and they spend their money to play gambling more and more. As long as we can control ourselves while we are playing gambling, we don't have to worry or afraid.
Those negatives and positive side of gambling is just a reminder for all the gamble players. I know that all the gamblers know these two sides and still playing. I agree that we should regulate ourselves even though it has a positive sides. We have the saying that "too much is bad for everything". Just have a control on yourself when playing gamble.
