It sounds like he is certainly not in a completely rational state. Substance abuse in the extreme makes that impossible. So it is probably a stretch to think that he will make rational decisions, now.

It is really unfortunate that he doesn't have close ones confronting him with his abuse and steering him into getting help. Maybe those close are just trying to milk the income, or perhaps they are at wits ends with not knowing how to take care of the problem.

It is just a sad, terribly sad, and impossible situation. I would bet that most of us would know, close at hand, friends or family members in similar situations, though perhaps not as public.
