>It isn't even debatable.
Yes it 100% is you fucking idiot. You're thinking of The Killing Joke, where he laughs at the Joker's last line. In TDKR, he straight up snaps the Joker's neck, and the last lines coming out of him are in Batman's font and grey speech bubbles. So yeah, he killed the Joker and is talking to himself. Somehow, The Joker breaks his own neck. (The comic has specific colors/styles for the characters you tard.)
