I'm re-reading the original Dune book, and in the end of (the inner) Book 1 (Dune) it says:
He had seen two main branchings along the way ahead - in one he confronted an evil old Baron and said: "Hello, Grandfather." The thought of that path and what lay along it sickened him. The other path held long patches of grey obscurity except for peaks of violence
This is Paul's newly acquired Seeing, where he sees into the future. We know that eventually he chose the path of violence and Jihad, so I wonder: are there any details about the other path, and why it makes him sick to think of it, even more than the violent path?
Note: I'm talking only about the book(s), not the movies.
