Reply #4: The world is much more nuanced than simple black-and-white choices.

Accepting your premises for the sake of discussion, why must the relationship between people and "fallens" be a binary option of either destruction or salvation? Why is there no possibility that the two groups were meant to simply coexist? Why no possibility that they were meant to never interact? Were the "fallens" cast down into Eden, or outside the Garden? If it was outside, humanity would not have been meant to interact with them unless their expulsion from Eden was predetermined.

Also, why must human existence have a defined purpose and meaning?
