This is really a good question.

Before answering this I want to say that in this current era we all know about the weapons, and we also know that Police are using that to save our life  and on the others hand that terrorist used that to kill the innocent people. Here is the same thing what cases but we the human and using that sometime in a right path and also sometime in a wrong path.

So yes in my personal opinion, I would like to say that the main problem is on us and that is our greed what we can't control and as a result we made the gambling a cause of our sorrows instead of having fun.
