If the resurrection of the Demon King is dependent on the completion of the back-up vessel, he can simply kill Fiona first, prior to killing the Demon King. He might not prefer that option, but will he, eventually, have any choice?
When he had defeated the demon king, the brother was still moving after the demon king's soul left. Why not focus on a max recovery team that can heal the vessel after the demon king's soul leaves? Nearly kill her, then heal her.
