The defeat of evil would occur in a case in which some state of affairs contains a bad part that is worse than the whole, even though the whole does not contain any good part that balances off the evil of the bad part. Consider Case 3 in which I take pain in what I take to be my bad behavior. The badness of my pain may be mitigated by the fact that the object of this pain is something that requires that pain be taken in it — my own bad behavior. But it is possible that I am mistaken about my bad behavior; maybe it never really happened. Thus, Case 3 does not contain that bad behavior as an actual part. The state of affairs may have no good part to balance off the badness of my pain, and yet it may be, as a whole, not as bad as its worst part. (It may be neutral; or even good.)
