Gambling with someone else's money is a very bad idea.
It's an idea that we shouldn't do. I will not going to use others money just for my own sake. I'll feel shy to myself and my family if they'll know that I did it just for the sake of gambling. Very bad idea in a way that what are you doing with your life for the whole time? You shouldn't be relying on gambling and this deed is not a good deed for other gamblers since they will find it out that you are an irresponsible one.
