In episode 142 SK say about God Hand: "...if there's a place where the mind is too strong, they cannot bring their bodies along with them".
So probably "right to choose" is real, and can be used against God's will.
Ok. Esclipse. Why God Hand didnt do Femto by force? Because sacrifice is "act of will". It proves that idea of "freedom of will" is important in Berserk.
Then. Miura want to show us the differece beetween "true" and "not true" darkness. We know that Griffith must be true, but dont know how it...
Yes, we dont. But we can speculate about near future, basing on what Griffith Reborn done, and How! he it done.
He need Pope. He need Charlotte. He need people of Midland, alive. If he want to do hell himself, why he didnt take rule by his own, Femto force?
And in the end, true Devil always...
Ok, but if he wants "kingdom of hell", why all this "defend pope! defend people!", cakes from Charlotte. Yes, i know Femto wants Hell :guts: But he wants that people do it themselves.
