Could also be explained by him being a complete moron, in addition to his other wonderful traits.
The difference between 'insane' and 'so stupid that you think a vagina can grow between your dick and your asshole" might be philosophical but I still think it's there.
I don't really think that he's hearing or seeing all the bullshit imaginationland stuff he says he does, for example... although it's impossible for me to know. Maybe someone can tie him up and put him in for an FMRI...
No, I don't think it's mere stupidity. I think Chris' handle on reality is nonexistent.
I explained it in another thread, but I'll repeat it here:
Some people think that Chris cutting his taint open was him being a dumbass, but they ultimately think it was just a drunk, spur-of-the-moment thing. Someone said "you're not a real woman" and Chris was like "I'll show you a real woman

" and grabbed the knife.
The reason why I don't believe that, and why I think it goes deeper, is because Chris had been rambling about his vagina growing in for at least a month, if not longer. He claimed to feel a lump in his crotch that he believed was his clitoris. He's incredibly dumb, and gullible, and little signs like that, signs that he's right, they go straight to his head.
Chris really did believe he had a vagina growing in.
In fact, I think he still believes it. He just thinks that maybe it needs more time to ripen or something. (

)
I think Chris has reached a level of stupid where reality doesn't matter. I don't think Chris is mentally capable of picking apart reality from fiction. I think he's diagnosable with something.
When Chris tips that rock or crystal or whatever in his hand and it falls forward, I think Chris gets excited because he thinks it really did fall forward via his mind. He's not capable of perceiving it any other way.
Chris doesn't have any loyalties to himself and his parents, and his loyalty to his parents is waning. To me, if Chris is a legal adult in the eyes of society, he should be held to the same standard. It's not everyone else's fault he's exceptional.
It's not Chris' fault he's insane. He needs to be under someone's care.
