Was thinking about it and- what about a demon whumpee? A demon whumpee that somehow gets above, to the earth, suddenly and not of their own free will and just trying to survive there?
Imagine them their whole life living in hell, the hot place, and when they appear on earth, they constantly feel cold here (especially in some countries of the north), which they have to get used to?
What if they were used to know that good is bad in their twisted morality — and now, with kind people surrounding them, they feel just... lost and defensive. Not able to trust anyone.
Maybe whumpee will join bad people, bad relationship because they will feel that these are right, are normal, because they are like most in hell. Maybe they will tolerate pain in their presence, because it's just right, isn't it?
Their life used to be hell, surrounded by bad, by wrong, and they grew up believing it's right. Will there be people here to see through the demonic origin and find a suffering soul in need of salvation?
