In such cases only one thing can solve the problem, namely faith and the priest, there is no other or other way to leave the family life and look for a new life, maybe it can be avoided from all forms of gambling activities.
What's more, in the family there is unemployment, every day everyone in the family enjoys money from gambling, if that happens all generations will have an impact on gambling, so as I said above to prevent the younger generation from getting involved in gambling.
