Here's some Chara Dreemurr headcanons:
They have Gifted Kid Burnout. You can see this
on their completionist mindset: the highest
numbers, the fullest glass of water...the highest
grades?
They struggle showing negative emotions so they smile when they have them, like when they accidentally poisoned Asgore, or as a narrator, when they said this:
They also show the ability to change their behavior by learning:
Also, since every character I fixate on so far has shown traits of autism, they might have had it too. Or something similar. (Moral OCD would be interesting, but with a sort of opposite twist. Immortal OCD I'M AWARE THAT'S NOT A REAL THING. Probably not, just a thought. Would make an interesting AU; In all their actions, they choose the most 'evil' possibility)
On the surface, they were blamed for a lot of bad shit. I imagine they are or were clumsy, and got in trouble for things out of their control. So, they began to try seeing themselves as inheritly evil, to demonize themselves and to cope. I can see them thinking "Well of course I did this bad thing, I'm a demon after all" to excuse their actions, or to avoid guilt.
They probably have some kind of religious trauma, probably from christianity. (idk enough Christianity lore to go into a lot of specifics) Under the cut, I proceed to go into the limited specifics I do know, feel free to correct me.
