4. "You're Going To Be Spectacular"
https://www.youtube.com/watch?v=-F9bAGpJVl4 One of Arkham Knight's recurring themes is the question of whether or not Batman is ultimately helping or destroying Gotham by encouraging a whole new breed of madness. It's something that's been touched on all throughout the character's history in comics, films and games, but Arkham Knight takes it to a whole new level. By inadvertently creating the Joker, Batman birthed the antithesis of everything he's supposed to inspire - whereas the Caped Crusader stands as the ultimate example of what's possible when one person dedicates his/her life to making the world a better place, Joker represents chaos, and just how easily a person can be driven to depravity and madness by "one bad day". It's remarkable that despite the Joker's demise, his influence is so pervasive that it permeates every second of Arkham Knight, and when it's revealed that his mutated blood has infected several Gothamites and essentially transformed them into copies of himself, it looks like he's finally had the last laugh. The fact that Batman himself is eventually revealed to be the final Joker is just the exclamation mark to a sick joke, and Henry's last words serve as a stark reminder of Batman's capacity for evil should he ever lose his way.
