Um.... No. Flowey never lost his power to SAVE, it's just that his own file was temporarily overridden until Frisk either left the underground or they were killed.

And Undyne has the lowest (besides none) level of Determination of any monster in the underground. Boss Monsters like Asgore, Toriel, and Asriel all naturally possess determination because of this. That's why their souls persist after death (not including Asriel).
