Gambling addiction can have negative consequences, which is why many people speak negatively about it. The same can be said about smoking, alcohol, sweets, and other habits or pleasures that can cause problems when abused. But this does not prevent a huge percentage of people from smoking, drinking alcohol, and eating sweets. Moreover, some people love all of these things.
If gambling is really something that is bad, people would not even see it as interesting and would not engage in it, because nobody perceives what is bad and then decides to pursue it. Gambling is not inherently bad, but people can become worse due to their greed and desperation.
Gambling is fun and interesting, and sometimes it comes with a reward if you are lucky; that is why people find it intriguing and choose to take it up as a hobby. However, the reason gambling is seen as something negative is that people often go beyond their limits in the pursuit of winning money. Setting aside greed and desperation, gambling is primarily a game driven by these two factors.
