Paul is not, like, a great person in Dune. He has a reasonably acceptable sense of honor, which, frankly, puts him in rare company in the books, but he’s not a “Do the most good you can for the most people” kind of hero. He believes he’s God after a while, but all that’s happened to him with his prescience is that he’s discovered how much he’s a product of his circumstance.
But he hasn’t realized that yet at this point. Right now, he’s super excited that he’s not only the Kwizatz Haderach, but also has a hot girlfriend whose dad likes him because he’s, what, like 17 when he starts leading the Fremen in terrorist attacks.
Around his neck, you can see a water coin. It’s inspired by the cover of Herbert’s short story collection Eye, which was painted by Jim Burns. In it, a Fremen woman’s hair and scarf are woven with water tokens to show her family’s wealth, and I really like that imagery.
