And not the “white boy 16 year old” who decided it was more important to have his grudge, his revenge than living happily in the desert instead of pursuing the revenge. He had his eden but his revenge was more important.
And once he started his revenge he just decides to butcher 60 billion people to maintain his “authority” for there can only be one source of authority. The space guild needs his spice but they have enough storage to attempt a coup with one of the various armies besides the Fremen. Thus the white boy 16 year old decides it is better to put down 90 planets sterilizing them completely so they are Inhabitable, terrorize 500 more planets, and destroyed 40 rival religions.
But no it is the black people who did this not the 16 year old white boy who becomes Hobbes Leviathan because he got high on Mescaline. It was this white boy who ate the tree of knowledge and became wicked, who became mălum.
