Actually, addiction is one of the most painful illnesses for humans to deal with on this planet.

People who are in the throes of their addictions will change someday, but not until they really want to, and some of them will die first. Especially, that might happen if they got rewarded by an imbalanced culture for a long time for indulging in certain kinds of addictions. I do think that being overly controlling is a real addiction for some people. They probably should have rehab clinics for that kind of addiction, too.
