I think that those who are addicted to chronic gambling turn into psychopaths, they start robbing, stealing, manipulating, they really can't feel the pain of the person who is the victim
I once read in an article, several rich families in a country advised their families who were addicted to gambling to undergo brain surgery, the aim was to change their behavior to become empathetic again like other normal humans
I once came across such kinds of people and they even bragged about their milestones some of their stories are alarming because when they rob a home without anyone inside, they get everything they can from the appliances to the foods in the refs and sometimes they even use the comfort room to relieve themselves. Their reasons why they are doing these things are all related, whether they're addicted to drugs or they badly need to finance their gambling activities or to pay some huge debts which we all know doesn't really make sense at all. Those who can't stop themselves when they feel nothing is going to benefit them from their habits are those who usually fall for this kind of thing especially those who don't take advice from anyone at all.
It's mental disorder to inflict pain on other people for the sake of gambling. Players with such level of addiction deserve the brain surgery mentioned above. And these are just little compared to what other mentally disordered players do across the world. They neglect the needs of staying responsible for a very long duration. It's like repeatedly making mistakes, the person will get into problem.
With no observation and caution from family or close friends the gambler's problem will worsen off. Yes, addicted people are countervailing in nature. But the few close observation will help reduce some weird behaviors from the addict. Because, neglecting the addict is shooting ourself on the leg. The player will definitely fetch huge troubles for the family. Though hard to do, but it's worth doing.
