Well that's true. It's like forcing someone that isn't willing to change to a rehab center and doing the same thing after getting out of a rehab. It's just wasting resources, money and effort on someone that no plan in doing the right thing for himself. It's hard to help gambling addicts if they aren't willing to help themselves knowing how easy it is for them to access casino nowadays.
I like your point here, they have to determine from their heart to change if not everything will results into wasted efforts if care is not taken, there's a stage an addiction will get to and go beyond control except if the person involved willingly determined to change but it would have been too late i most cases because they would have been seriously dealt with and left with no other alternative to live than quitting.
A gambling addict that has a resolve to change even without any help is much better than a person who has all the help but isn't willing to change at all.
Yes, everything comes with determination from the heart and not through pretence or by force.
