Paul Farquhar
Legend
Paul Atreides has a strong resemblance to several villains from the Conan stories (and the movie).But they were struggling on Arrakis, and found some satisfaction and balance there, albeit with some oppression from their colonial rulers. They were engaged in finding meaning and fellowship while contending with a harsh world for survival, which seems very much in keeping with Howard's/Conan's ethos. They were masters of their environment, even turning the apex predator into a steed and beast of burden.
I don't see the galactic jihad as particularly life-affirming, no. :/
