I agree with you that movies need to keep the story simple and the number of characters parsimonious. I would like to note that the stories that came out at the time the casting of Adewale Akinnuoye-Agbaje said that he would play both Algrim and Kurse. That implies that he will be transformed. Likely it would be an entity like Surtur that will be referenced in the film anyway, and may appear (rather than introducing an otherwise unneeded character like the Beyonder). And likely they won't have as much about Kurse charging around trying to get at whomever he holds responsible for what happened to him. So maybe he won't get amnesia. But it seems that the transformation part of his arc is more likely to be shown.
