Who is the One? Out of each world the Father only begets "One Only Begotten Son!" From this world, the Messiah will only beget five Sons in worlds to come, excepting in the rare time when one falls as Lucifer did, and then their is only four. The world that has a fallen one like this world where Lucifer was cast down to, is the most evil of all creations or worlds of the Father (the Messiah that only had four heirs). So when you ask why is it getting so evil, and the world never ended yesterday, as the Mayans thought, this imbalance of evil was probably overlook in their calculations.
