I don’t see addicts as bad people. I know of many good people with addiction. It is powerful. I do find myself viewing it in terms of an illness. I have seen those cry when told there liver is failing and promising themselves and others of change – only to see the person back in the ER later. Is it a habit? Well if you were told you were going to die or lose those close to you if you keep biting your nails, I guarantee that you would stop.
