This is, unfortunately, a much more common occurrence. Then, of course, there is the issue of bookmakers and betting sites acting unethically.
Nonetheless, if nobody is being affected by a person’s gambling other than the gambler himself, I don’t see how there is a moral conundrum to debate. Special circumstances such as these definitely seem to complicate matters. For instance, if someone who has children and a family develops a gambling problem which results in them losing their family’s life’s savings.
However, I am willing to acknowledge that there are stickier moral gray areas when it comes to gambling. This is an argument that I have never quite been able to grasp, personally … the way that I see it is if you want to put your own money in jeopardy, that is entirely your business and your business alone. First off, in the most extreme cases, there are some who believe that betting of any sort is immoral. The discussion of ethics when it comes to betting sites and online gambling is one that is often ripe for debate.
