In the 2014 movie Annabelle, near the end, it's revealed that Annabelle the doll is being possessed by a summoned demon and needs a soul sacrifice in order to leave the child of the protagonist alone from harm.
An elderly woman that the protagonist has befriended a while ago sacrifices her soul by killing herself to save the child. The demon accepts it and leaves the protagonist's family alone.
However, at the beginning, we see a young woman named Annabelle from a devil worshiping cult, killing herself in a ritualistic manner when they perform the summoning ritual of the demon at the protagonist's home. Wouldn't this mean a soul already has been offered to the demon at the very beginning?
