His son, Hunter, is a Drug and Alcohol addict. Much of the bad stuff he did in the past, he justified as only an addict can. He is currently working a program. That program requires him to take his lumps and make amends for past miscreant behavior. You are not required to give him any special treatment. The pain they cause is often unforgiveable. But, once they are working a program, they will do all that they can do to avoid doing bad things again. That is enough for most people.
