I can understand where Joe is coming from though. He was begging his parents to do something when Andy was living with them and making their life a nightmare. Now something has been done. Andy is gone and I can’t blame them for washing their hands of it as much as possible. Besides, what can Joe do? As much as Andy pretends otherwise, he’s an adult with full decision making abilities. And I think that despite what he says, he would never allow anyone to get a conservatorship over him. Andy acts like he wants to be treated like a baby, but we all know he craves power over others and total control.
Joe probably doesn’t have any more proof he’s going to molest kids than we do, so there’s no point in calling his group home and warning people his brother is a huge fucking freak. They already know, and people like Nicole who are stupid enough to fall for it aren’t going to listen to Joe. Unless Andy told him “hey joe me touched a kids weenie” or sent him some CSAM he has nothing to report.
Joe’s in bad health and just lost his mom. He probably just wants to forget Andy and let him be someone else’s problem while he moves on with his life. There’s not much you can do to control a trainwreck sociopathic disaster of Andy’s caliber anyway, and it’s not his responsibility. All you can really do is get the hell out of the way while Andy ruins his life.
