Sup, often gambling is blamed for making people part with their money, or casinos are blamed for existing, or government is blamed for allowing gambling in particular country, and along the lines.
Point being, just because there is gambling available, at the end of the day, it's individual's own choice that (s)he decided do it, and no one is to be blamed except oneself if something bad happens.
Do you take responsibility for your losses, or do you play blame game?
Every one is to be held responsible for their actions whether the outcome is good or bad. Let me ask you; would you blame casino houses if since you started betting, you have won more than you have lost? People usually get antsy and shift blame to others but themself when things don't go their way so it's not a surprise.
Personally, I like to blame outcomes and circumstances when a game I staked doesn't go my way but later tell myself the truth and observe it, when you take responsibility for your actions, it's easy to live yourself when things don't go your way.
