I've said as much earlier in the thread and I'll say it again without powerleveling too hard but taking care of an addict with a mental health issue is hard enough as it is on people with resources. For all of his flaws and mistakes, Clint is still a good father who tries to do right by his retarded child. He's only human and I don't fault him for wanting to focus on his own life when he has a son who can scrape by in life without killing himself, despite all of his vices, because you CANNOT force an addict into rehab and you CANNOT force someone with a mental psychiatric diagnosis to go to therapy, what makes you think you can force a boglim to become a model citizen when he can't even tell sweet tea from regular tea apart at Wendy's.
It's a meme that Clint is a bad dad for not sending Josh to a group home but again I wish to stress that you can't force someone to take their medicine or wash their clothes, or stop shooting ropes of cum on the carpet because it's goth as fuck.
Josh is beyond lucky that he has a father like Clint. A lesser man would have and should have washed his hands of the bog problem years ago. People have cut contact to family members for less.
