I have not seen any case of gambling addiction seen from the angle of being spiritual motivated. It's just like other types of addiction like drugs, alcohol and others. It is best viewed from from the angle of poor mentality than any other thing. It is poor mentality that leads to greed, desperation and all negative things that manifest as gambling addiction.
I agree with this, the reason for addiction is a poor and weak mentality this is why a lot of people that are addicted lack restraint and will power to control themselves. some religious people see this as a spiritual attack and you can't blame them for the what they believe in because it's probably the information they have received or what they have learnt. To stop an addiction you must change your mindset
