Forum:Are the nightosphere demons ex-humans?

I'm going off the theory that the lith is finn's dad, simon is ice king (thats not  a theory) and hunson abbadeer was humanhttp://neko-minos.deviantart.com/art/The-Ice-King-The-Lich-King-and-The-Lord-of-Evil-376703260

If you had a way to save all humanity (or most of it), even if it changed them into demons and corrupted yourself, would you take it? Maybe marceline didn't want to go, or maybe her mother was pregnant at the time and didn't/couldn't go. It may have been Simon and the great mushroom wars fault; Simon was going insane, the mushroom ars had mutation effects and killed many humans (the lich/finn's dad).

Makes sence right? Save them by makeing them demons, at the cost of you'r own humanity.
