I was curious about that spoilers:end of spoilers
The way she said she "destroyed" all the Supermen and how she doesn't seem evil so much as beaten down in that reveal makes me think she isn't exactly evil. No one left should be evil if the World Forger is telling some sort of truth. I wonder if this job as the jailer of Apokalyps, along with Jon still being active with Damian, makes me think it's some kind of self imposed punishment because she blames herself for Superman not going along with the plans. I'm thinking she also might end up being the new ally the solicits have teased, though I suppose it's possible that it's a villain.
I wonder if there is going to be some element of Civil War II-esq they imprisoned people who didn't do anything and may not have been going to go bad. Like the method they devised (I'm thinking likely set up by Batman) to determine who would side with them had some false positives, maybe even Lois herself, and that is one of the reasons Superman wouldn't go along with the plan and he ends up in the pocket universe? We know Batman apparently sides with the World Forger eventually.
