User blog comment:IamJakuhoRaikoben/Chapter 449: Mavis & Zeref, Review./@comment-7418318-20150824075033

Very nice chapter.

It also strengthens my theory that Zeref's assumption of him being cursed was done as divine punishment by the god is wrong.

Zeref thinks that Ankhesam cursed him due to playing with life and death. Mavis never did that. All she did was slightly mess up a spell that wouldn't have killed anyone in the first place, so why would Ankhesam take notice of this and punish her for it?

If Zeref had been right, it would make no sense for Mavis to be hit with the same curse. So my conclusion is that Mavis either was hit by a different kind of immortality curse or, as I said before, that Zeref was mistaken in his assumptions of how he got cursed. After all Ankhesam never came down from heaven to tell him stuff.. Zeref just came up with the theories on how he got the curse and found out how it affected him first-hand. There's really no proof.
