Not to mention the fact, they are playing with fire as you just can’t go to the Underworld and expect to waltz out without dragging something back with you?
There’s something slightly immoral about the Savior waltzing into the Underworld and only saving one person. If Emma’s goal was to put a stopper in death and save *everyone* who had repented and asked for forgiveness, that’s one thing; that keeps nicely to her Savior trope, especially on a show where the leading cosmology of the writers is a Judaeo-Christian one. But seriously, how can the writers justify Emma going down to the Underworld and not save other innocent and lost souls (souls that are more innocent than Hook)?
The way Rumple talked about the Underworld, you went there no matter what (which does keep with some Greek myth) but that the Underworld as a whole was terrible (which does not keep with Greek myth). This doesn’t even have to go back to Neal and him as the elephant in the room, but what about the poor souls in the village Regina had destroyed? What about the Ava’s of the world (mostly innocent mother who was murdered?) The Leo’s? The victims of Rumple, Cora, Pan, Regina, Hook, and the other villains who were bent on their endgame and didn’t care who got in the way? How does Emma, as the Savior–and moreover, the SHOW–justify that they have to remain in “hell?”
