In short, gambling is your helping hand into suicide. I've heard many times where people took their own like so just they can escape the huge debt they owe from influential people they know. They would be killed anyways so they just made it early rather than getting tortured first before they are dead.
This is wrong how can you blame gambling instead you should blame the person it was his greed and his foolishness that cost him his life. Even I was in debt I didn't die, I simply worked hard gambled responsibly, and overcome that phase it was a long struggle but I managed it nevertheless. So I don't think gambling is wrong, blame thier mentality and approach.
Gambling should take a part to be blamed, in the first place no one would be addicted on it if it doesn't exist on the first place, yes, it is our choice what to make when we are playing gambling but what's not right is if we are going to put the blame on ourselves even though we know we did our best to prevent something to happen like coming to a point where we wanted to end our lives because of mental problem caused by gambling.
And we don't need to compare ourselves that we didn't die or get depressed, we have our own solutions to solve a certain problem, we might get depressed or not, depends on how mentally strong we are.
