Totally. Could not agree more. People will talk about Heath but this is the scene I loved the most as well.
Heath was phenominal for what the Joker's part of the film was, but at the end of the day, the Joker was more a circumstance than a character persay. Batman's interaction with him wasn't as personal as Ra's, he was a threat, but it wasn't too often about them one on one. Joker was a threat on Gotham and the movie was about the White and Dark Knights taking that threat on from 2 different angles and the 3rd act of the film was the culmination of that plot with Harvey and Batman's fates being sealed.
