If he had Determination he'd melt, wouldn't he?

He's clearly not dead. None of the skeletons, ghosts, or other 'undead' monsters are undead, they are monsters that look like things associated with death. And none of the monsters in the game are the human souls revived. We SEE the souls, Asgore has them.
