I think part of the Path of Light is that you can influence how Dal Quor will be reborn. So, sure the next set isn't for sure a Good Place, but you can push it that way by pushing the Path of Light.
The Dreaming Dark doesn't know what the next path will be, they just know that it WILL be an end to the current one, and to them.
