Bro, Nolan was totally planning on making Joker a villain again in The Dark Knight Rises, please bro believe me. I don't have any official sources, I just know. Nolan was planning on making it just like The Dark Knight again, bro it'd be so much better if it was just Bane and Joker, Joker said we were destined to do this forever. TDKR just isn't complete without Joker, believe me bro.
