You are right about the mind of gambling-addicted people being blind which is what makes them please their lust. I can remember when I was a drinking and smoking addict. My mind is blind from seeing the side effects of what I am doing while it is open to the special feelings that come with the intoxication but I never blame someone for it and I can say that's what helped me.
Because of this, I said that gamblers who blame others for their addiction are irresponsible and will have a difficult time recovering.
People who are addicted to gambling can be said to be those who are indeed blinded by the victory in gambling which is actually not something they can get easily. People like this usually cannot accept the defeat that will and may have happened to them and this is what can make them conclude that gambling is a fraud when they have gambled in a casino that previously said that they would definitely withdraw their winnings in the casino.
Saying gambling is a fraud or blaming others for the defeat of the gambling that is done is an irresponsible behavior, not a right thing with both of these things.
