Y'all going too fast. I know from two close cases of going nuts (Well it was after some drugs) and in most cases those people when gets out of the nuthouse/whatever place they been into (Even considering his autism) they need some time to be able to front the consequences of their actions.
I think Chris as some user stated (Arround the page 77 I think) has already accessed the internet, probably even with his old phone. Just because his Facebook profile just been deleted yesterday for no reason at all. After stating that I honestly think that he will need time to find a way to confront what he did.
Don't get me wrong, I know he's used to being trolled and stuff like that but this time he broke the last few ethic strings he had left. Im pretty sure that he got some MKUltra level brainwash in the Jail/Hospital in order to make him realize how wrong is what he did. And surely he knows that the vast majority of people in the net is against him. Just consider that if he has access to the internet he can see that he's often trending topic and that even people that never been into lolcows now know who is him.
Even if he continues being literally nuts with that Yisus and the merge stuff he clearly sees that he's not welcome anymore. At least not easily. He can't just post on Twitter "HEY ITS ME JESUS CHRISTINE WESTON CHANDLER OF SONICHU AND IM FREE AND AT XXX PLACE RIGHT NOW" because he knows people will bully him until the end of times just for what he did.
Plus consider that even if he's not on heavy meds any sort of meds he surely is taking after all of this made him change at least a bit his POV.
Im sure that even if he doesn't has not full restrictions on his internet use he sort of gets what vibes has the people in general against him. As always there will be a couple of enablers but this time is a point of no return.
