Most of the people here believe that that's only a villain based picture.
What if it's more about the two main factions (could be more of course because of potential intrigues and so on)?
What if these few characters on that picture belong to a much larger picture, that includes few regular superheroes including Batman and Nightwing who lead them?
All the characters on the list, I could see them being against Superman and therefore the "villains" in the story, because Batman is once again the vigilante who breaks the law / Supermans law.
Let's say it's Circe and Raven on that picture:
Lex Luthor hates Superman, teams up with Batman.
Joker is afraid of Superman, he teams up with Batman.
Circe hates Wonder Woman, teams up with Batman.
Sinestro hates Green Lantern, teams up with Superman.
Raven is Nightwings old team mate, so she sticks together with him and is on Supermans side.
Deathstroke and Bane are there, because they dislike Supermans methods.
