nothing is wrong in this world, it is upto you how you approach and perform, gambling in casinos and dice games are clearly known that no one can win with the house. out of 100% only 10% wins because they just play for some time and after winning they leave this site or game and go for another site or game. but for long term they lose everything even their savings.
How is this? Nothing is wrong? And the killers of innocent people? How about the politicians which exploiting their positions and the trust given from the simple people to become rich stealing money everywhere and where they can? How about the thieves which take everything earned with the sweat and effort, sometimes even killing the people who steal.
As about the gambling your position is the position of someone indifferent related to the problems that cause bad thing. It is not so simple like you write. Gambling is not a simple game but an evil one. Attract with the fun and the hope to win when everything is calculated to create addiction from it and loss of money. The hope to win make everyone greedy and every win will go again in the pockets of the owners of the gamble owner. As has told someone here in bitcointalk in his post. The casino know that every winner will come back again in casino to win again. And that's the end for him. He will lose all the money won and even all the other ones have in him's pockets.
No no no. You cannot compare gambling to killing people. That is just silly. Gambling is a thing you can do, no one is forcing you to do it. Just because a few people in the world have a problem with it, doesn't make it a bad thing. I enjoy gambling for the fun.
In general, the world needs to stop conforming to a few bad apples. Oh they drank too much? ban alcohol? They gamble too much? Ban gambling. No, fix the problem with the people doing it, don't ruin it for everyone else.
