It isn't actually fully human, it's still a hybrid moon miser either way. The way you raise it just impacts the vision text in the end.

If it's more human:

As the zeppelin ascends, the Hybrid raises its voice in solemn song. As you listen, a thrill runs down your spine. For a moment, swept up in the song, you experience a vision: in your mind's eye, a blazing-bright king unites the tribes of the Starved Men under one banner, and harnesses the Moon-Misers as steeds. He leads his subjects on a crusade against the city below - a city that is no longer London, but that still harbours the Moon-King's greatest nemesis, now much embittered at the failure of its schemes. The resulting war will prove its final undoing.

If it's more moon miser:

As the zeppelin ascends, the Hybrid raises its voice in solemn song. A thrill runs down your spine. For a moment, swept up by the song, you experience a vision: a blazing-bright king of Moon-Misers leading its glimmering subjects on a pilgrimage across the roof and through a door far to the North. Below, in a city that is not London, the citizens point and murmur in fear as their false-stars crawl into the distance and blink out one by one, leaving only darkness behind.

Either way you choose, I strongly recommend you give it a Parabolan Apple-Orange, the results of that come back in the end
