Wouldn't it be perfect if she, during the third movie, turns into a true follower of Paul Muad'dib as well, dying with the complete certainty that he is the messiah the Fremen have waited for while Paul does nothing to discourage her?
... be written as yet another tragedy to put a bleak finishing touch on everything. Villeneuve changed her story in part two so that she's much more independent than in the books, doesn't accept Paul as a messiah, and wants him to renounce it. Wouldn't it be perfect if she, during the third movie, turns into a true follower of Paul Muad'dib as well, dying with the complete certainty that he is the messiah the Fremen have waited for while Paul does nothing to discourage her? I want this movie to really hammer home the audience's realization that Paul is destroying the Fremen forever, including his loved ones.
