Not sure if this was mentiond or asked.

Its been bothering me since i thought of it. Im not sure if this has been explained or thought up before so sorry if it has. I also dont know if it was explained in the seocnd eclips or first. But here it goes...

When Griffith was transformed into Femto is it posable he was reborn knowing that he was able to be reborn by tainting the unborn guts/caska baby? thus making it his plan to not be Femto for to long so he can be reborn as his old yet new self again?

Or was it mentioned to him and it gave him the idea? I remember readin something about Void saying every 1000 years a baby is born and a godhand can be reborn. Im probably incorect so i must be guided to the right direction.

So bascly i wish to know if it was his plan all along to be reborn from the begining when he raped her or was it an idea given to him.

No, he didn't know. However, as a human, he had no more paths to be king.

Femto raped Casca to hurt Guts.
Causalty led from that encounter into his rebirth.
