Everything in life is a gamble; heck, even life itself is a gamble, so essentially, gambling (for me) isn't wrong. It only gets wrong when you are tossing someone on harm's why just to satisfy your gambling habits. That ain't cool, and that is wrong. When it's only your own sake that's on the line, it's perfectly fine. It's your money and decision after all.
I agree with you, Gambling isn't wrong when you can control yourself and don't being addicted. Gambling is a good way to make myself feel good. I don't consider it like a source for getting money, It's just only for fun. I do it since a long time, I feel better when i gamble. Usually i gamble in sports betting which i have some skills in this sections.
