Yeah, in as much as people are getting addicted each and every day, they are becoming a nuisance as well as liability to themselves, their families and society at large, then, gambling will be considered as something negative.
Sure, we may want to argue it that this has to do with people's mentality and mindset towards gambling, but if we really want to face the truth, very little percentage of gamblers do it for fun while the rest are just after the money and as long as this is the case, we will keep seeing cases of addiction in the long run.
Exactly. Most gamblers are in it for the money rather than simply having fun. For people who had never tried gambling, then often lose more than what they've initially invested into a game due to lack of knowledge in the gambling sector. After not getting the results they've wanted, they quickly associate the term gambling as something very bad when that's not usually the case.
It has been seen that expert gamblers (especially in skill-based games like Poker and Blackjack) have been successful when doing the practice of gambling. Of course, they won't always win money, but they could easily achieve a return on investment by playing such games.
While most gambling games are based on pure luck and randomness, I believe that the positive traits of gambling are more than the negative ones. It will all depend on the level of perception a person has whenever he/she thinks gambling is good or bad for his/her life. However, if someone becomes extremely addicted to gambling, they'll lose everything in the long term due to the high ambitions of greed. Just my opinion
