They were sealed at the New Home end. Therefore, they couldn't see anything, and because they couldn't go out, the only thing they would fear is if the humans lifted the barrier and killed them all. That's why they retreated. They didn't know the humans could just pass through it freely. But even if they did, that wouldn't change anything.

Now, if you think that they were sealed from the Ruins end, then why did they not go past the Ruins, why did they stay so close to the barrier? It makes no sense whatsoever.

Also, you didn't answer my question. If they knew they had nothing to fear, they would never hide away in the Ruins in the first place. When Chara came, there shouldn't have been a city there. The monsters would have no reason to stay so far away from the barrier, if they really had nothing to fear. Remember, it was at least a few centuries by the looks of things. Surely it would take them only a few years to realize the underground has no exits, meaning that they had nothing to fear (again, not knowing that things can actually enter through the other side).

But that's another thing. The trash that was flowing there proved that stuff can indeed enter. When Chara fell down, the myth that they're safe has effectively been busted. And THEN, Chara proved them wrong, that humans don't want to murder them anymore.
