Quite a theory. [Albert nods thoughtfully as he considers Batman's words, glancing back at his horse as she nudges for his attention.] It's true that those are observable traits among a high percentage of those here. Many of whom I have spoken with have conducted world-changing actions in the recent past or are on their way to such a path.

Without knowing the backgrounds of those who have been trapped here and their own "insignificant" roles, it cannot be confirmed. But the restrictions of summoned monsters in this world would lend some credence to your idea.
