Is the Blessed Virgin Mary a Better World?

In Romans 828, we know that in everything God works for good with those who love him. Would it not have been a better world than if Christ did not have to be crucified or was not crucified in order to save us? I mean, this goes back to the diddekay and this, this oh happy fault, right? To me, again, this is going also a little far field into the question of the incarnation. What had it happened without the fall? That seems to say something really radical and beautiful about God.
