I agree that Chris isn't schizophrenic, primarily because he's not the right age for the onset of it, but the behaviors he's shown on camera/in letters since the beginning of the goddess larp are really not much different from someone like
this lady. They certainly both share the trait of writing stories about a delusion they hold that places them in a position of importance, complete with a cast of characters whose interests revolve around them - which they do not recognize as being fantasy. And they both dismiss detractors as being part of some kind of organized opposition against them specifically. I think if my only knowledge of Chris was just being shown a video of him during this larping period, I would assume he was schizo due to his disorganized way of speaking/changing topics and the commitment he has to his strange delusions.
It's hard to really even draw comparisons between Chris and anyone else who might be like him in order to figure out his mental issues, because I've never seen or heard of someone with his set of circumstances and response to them. The only other person I can think of is Randy Stair, but I don't know that they are comparable because Randy was pretty obviously intent on committing suicide due to some unspecified mental illness (maybe depression or bipolar, hard to say without knowing him more personally). Chris just seems to be an arrested development narcissist who has, unlike what most people would experience, been able to avoid ever having to change himself in order to survive. I kind of would like to see what a potential future for Chris would've looked like without the involvement of trolling, given that his current delusions seemed to largely stem from bad actors, though of course it was his choice to perpetuate them.
As for the current happenings, this might've been addressed somewhere (still catching up), but would any psychiatric evaluations that affect the case be available for public record at any point? I know based on having seen televised trials that evidence presented in the courtroom is obviously accessible to the public, but if his case doesn't go to trial I don't know whether that information becomes available at any point...
