The Last of the God Emperors

The Last of the God Emperors: There But For the Grace of God Goes God, published by Salusa Secundus: Karshak was a monumental work about Leto II Atreides by Professor Istrafan Koye of the University of Ix; it comprises at least 3 volumes.

Koye (who refers to Leto as "His Annelidity" or "His Ouroborosity") argues that the key to Leto's character is quite simply that he was an adolescent for the entirety of his 3,500-year reign. One must approach Leto (about whom his majordomos dared to suggest that he had "feet/segments of clay") as a juvenile delinquent to understand him.

This helps one understand Leto's repeated temper tantrums when his Duncans might disagree with him on even trivial matters.

Leto's love life
A classic "brat kid" could be that unaware of the discrepancy in his own life between appearance and substance. From Leto's last dictatel messages (recorded shortly before his demise) it is apparent that he had developed a mad quasi—"adolescent" — passion for the "incomparable" Hwi Noree. While sexual union was impossible, he mooned over her like a teenage boy in heat.

Leto kept repeating that it was his ancestral memories of rampant sexuality satisfied him. Koye cogently argued that if the memories of licentiousness were enough to sustain sexual needs, then so should memories of gluttonous banquets should replace the need for food, yet they didn't sustain his physical need.

Breeding program
Koye also was the first to articulate the incredible contradictions between Leto's Golden Path/DE (at the heart of which was giving essential freedom of humanity) and the breeding program he had taken over from the Bene Gesserit (to plan to breed humanity into some higher type). The two stood at the opposeite ends of a scale.

Koye even argued, with some accuracy, that the Bene Gesserit were far more successful with their ages-long breeding program than Leto was with his.
