Dune is not a white savior story though, and neither is Dune Messiah (which Frank Herbert wrote in part to make that message as clear as possible). While Paul is trying to be a savior figure, he's using everyone for his own ends the entire time. The top comment on this wonderful video says it best:

Dune’s entire historical narrative has always been, “Beware of the Tyrant wrapped in Savior clothing.”
