Reduced? He went from a desert chief to probably conquering whole planets.

I ask?

How did he take advantage of them? Was it because he wanted to seek vegence for his father and used the Fremen? The Fremen hated the Harkonen too, and not only that; the Fremen hated the occupying houses of their planet. How is morally or ethically wrong if your goals align? He made it quite clear to Stilgar, Choni, and the Fremen people in his command that he wasthe why and how. He tells Stilgar and Choni verbatim about his father, and why he does what he does. He tells everyone in his command during the acension speech to the emperor. Through his leadership he took back Arrakis and saved the Fremen. He did so with the least amount of casualities, and he genuinely cared for the people in his command. How is any of that evil? He even outright refused to kill stilgar, he fought his own battles at the forefront on the ground along side his people and did h2h combat with the emperors champion in lieu of someone else in the final scene with a 50/50 chance of dying according to his timelines vision. If anything, it was the Bene gesserit are the real evil. They orchestrated everything, and have been manipulating all the houses all along including the lesser groups of Arrakis (fremen).

​@@xw33b36 Paul said at one point that if he took control billions would die AND he still took control. the point is that when Paul took up the fremens to fight the harkonen they believed it would stop there and what would come next would be building paradise. So you tell me if its morally wrong to make a nation-planet be your weapon of mass destruction just because they believed you would lead them to paradise. (pauls action actually did lead to a better future for humanity but its so far down the line that stilgar's great great great - (you get the idea) grandkids wouldn't even experience it.) He may do things honorably but that doesn't detract from the point that what he is doing morally fucked up and evil. (things can be grey , surprise surprise)

Stilgar lived a long and prestigious life under Paul and his son Duke Leto II. He even wrote a history book about paul and their time together on arrakis. He only laments that when arrakis becomes a paradise, his people abandoned the fremen way of life and basically killed their entire culture in the process. He died happy and satisfied. He didn't bore witness to the horror that is to come when Leto II turned into a tyrant.
