Couldn’t someone believe that prior to the creation of the world (that is, while the blueprints were still in the conception stages), God needed Adam and Eve to fail in order for his final plan come to fruition?
Certainly this is the position of some early Christian theologians, who tied the Fall of Man to the coming of Christ. This is the theme known as “Felix Culpa” (“fortunate fault” — that is, it was a good thing that the fall of man took place).
