When I'm looking everywhere on this website, I see people who say, yeah griffith, femto and griffith reborn are exactly the same person, well, at least the same spirit.
What it appears now when I read the manga, is that griffith reborn looks much more humanist than femto... I mean, when guts and griffith talk to each other at the grave of the hawks, griffith doesn't provocate him like he did when he was femto (first at the eclipse and then when they see us at the ceremony with the count). Plus, he holds caska in his arms, and in many points he looks like the first griffith (his behaviour in his new band of the hawks). Actually, we know that he doesn't feel sorry at all for what happened at the eclipse ("it seems that i am free") so it proves that he still doesnt have any humanity left , but, his thoughts, especially about the baby of caska and guts are not really the type of thoughts of a demon lord i guess. Besides, he didn't really feel sorry either for the lost of men when he was still griffith in the golden age.
So I got two theories : the process of resurection in a new human body turned his heart , in spite of everything, a bit more human.
We all know that griffith is really intellligent and he knows how to adapt his behaviour to any situations, and maybe, he tries to appear more human to make human people closer to him.
