Obviously in your world drugs are common but not in mine. I know a couple of alcoholics but no drug addicts.
As far as this man being released from prison to see his daughter, it is a very sad situational and the child through no fault of her own will probably die without her wish being granted. I am sure he never though of something like this before he committed his crime. It is something he will have to live with for the rest of his life.
We all have to live with our mistakes, large and small and try to learn from them.
sorry typo Situational=situation
