I don't think as Gengo is as Gendo. He's more as Leto II Astreides, also 'the Tyrant' or 'the God Emperor' in Dune's universe.

Spoiler:

Leto had absolute power over humanity during 3,500 years and is responsible of the stagnation of Humanity under his rule and the chaos between his death and the Scattering( a giant diaspora across the universe).
He also lead an breeding program using his sister's descendants which created people invisible for prescient as... himself.
He's the definition of a dictator and a bastard but his 'Golden Path' 's goal was to ensure that Humanity would never be exterminated or be enslaved again and it has succeded.
I think that Gengo is trying something similar.
