Bruce Wayne is having an idenitiy crisis, split on focusing on vengence against the horrid criminals, or sticking to his no kill rule, while Dick Grayson is slowly going down that path (but doesn't in the end), and Jason goes into that path and doesn't look back, just to spite Batman. Deathstroke and Mr. Freeze are the main villains who hold their vengence with a tight grasp, making a good contrast to Bruce. Harley and Victor are mainly causing crime for their own gain, as expected. Firefly has a short but impactful appearance, mainly having a grudge for James Gordon, showcasing what terrifying threat Barbara has to face against in the future.
