Spas, the Pianist.

This man is the god of Trolls.

he's not a troll, he's an autistic whose entire life is made of the internet and the internet is fucking with him hard all the time

i nearly gagged when he spent five minutes on that piano player.

it was so awkward

I'm sure his rampage\suicide\committal will be front page news.

I'm guessing no. Chris always ends up sharing the most personal aspects and events of his life with the internet, I think he'd have mentioned a shrink at least once if he had one.

As for why, well his family does come across as being kind of fucked up, and are obviously kind of oblivious to what their kid is doing online. Granted, he's an adult in the eyes of the law, but still, they're his parents, they should have some idea of how fucked up, susceptible to exploitation and suggestion -- and just plain STUPID -- their son is.

Actually, I misspoke there. Chris is just of the age of majority; he seems to exist outside of the traditional child-adult dichotomy, and should just be classified as Broken and kept away from children, the internet, and young single girls.
It sounds like even the law sees he is broken -- supposedly, he gets/his parents get checks from some government agency for being such a fuckup. No word on whether they consider Chris an adult, or if he will be tried as one after "Ivy" reveals themselves as another bunch of trolls, and Chris flips the fuck out.

His parents prevented him from being committed when he was very young.

Yeah, I think that was a mistake.

...or kills someone else, lest we forget the most likely outcome, now.

DAMN IT WHY CAN'T I READ

All he needs to do now is draw their happy life together and he's in the clear.

It could work, but people would say the movie isn't realistic
