I would like to make an addendum to my post above.

As far as the whole destiny thing is concerned, the Golden Path, etc. I think it is all to some degree part of Leto's spin. He uses myth and prophecy to rule and manipulate. He may have clairvoyant powers and be so tolerant to spice through generations of breeding that he can actually meld with the sandtrout to become a worm, but, he is still human. He is a God to his followers, but he is still human. The bits where he talks of his sacrifice for humanity are all said to his followers. This is what he wants them to believe. I think he is bored, despite what he said, and that is his motivation for engineering his demise. But, since he is a God-emperor, he can't undermine his own credibility by seeking to openly do this. He must be the ultimate manipulator to succeed. Everything has to fit in with his mythology. It would be, come to think of it, quite a challenge to pull off.
