Maybe catching the curse from misfiring Law was just what the characters assume to be the reason for the curse. We have no proof, only their theories at this point.

I wonder if Mavis getting cursed so shortly after bonding with Zeref might have been a set-up by Ankhseram. It might have been either a way to hurt Zeref some more by providing a situation in which he started to love someone only to lose them, or Ankhseram might have used Mavis to give Zeref a way to overcome his curse, which would have killed both him and Mavis, but Zeref failed somehow.

I wonder if maybe the curse might be released once Zeref respects all life. When he fell in love with Mavis he still had an entire continent worth of "game pieces" who's lives he certainly didn't respect. That might have been what kept the curse running, while Mavis who respects everyone's life was released from the curse (mostly) and could die in Zeref's arms.

Of course that's just speculation without much basis, but it makes a certain kind of twisted sense for a god who'd cast such a cruel curse in the first place.
