Alphys is the one to blame for the Amalgamtes, not the human race! It was her experiments that resulted in the horrible fate of these monsters.

And humans fall into comas too! It's quite rare, but being "Fallen Down" was probably rare for the monsters too. Even on the Surface, monsters would be dropping into comas like we do. "Fallen Down" is just the state that monsters are when they're about to die naturally.. Kind of like we humans do. It has nothing to do with them being banished underground. We only want the safety of humans and monsters, and giving both humans and monsters the chance to absorb each others' SOULS and kill everyone isn't a good idea.
