The thing is.....well, just a what if? Ben is in prison, a mental patient, Nick is dead......that is on the show.
The question here is not about that. Just a "what if". I mean it could say "what if" you HAD to save one person ....Adolf Hitler or Mussilini................or perhaps Ted Bundy or Jack the Ripper.
Sure, we would all probably just let them all go. The word is HAD TO SAVE. Obligated to save.
I found the choice of area to be interesting. Some years ago, Andre & Tony DiMera had a battle to the death in quicksand. The camera work was great, & eventually Tony was able to make his way to shore, pull himself out, and watch as the last sight of Andre was his hand, slowly dropping below the surface. Tony was the victor, Andre dead.
And yet, somehow, with no explanation, as is usual int he case of Days return from the dead characters, Andre appeared again and again.
Just a rhetorical question.....sorry it just did not go over.
