The Lego Batman Movie was an absolute joy and a gift to the world! Had a lot of fun drawing the Gotham peeps.
I understand that for this Bruce has to forgive everything which is impossible. Though still at the end of The Killing Joke it was rather interesting how he laughed with Joker on the joke like best buddies (even after what he has done to Barbara and Gordon.) I just wanted to answer to you saying Batman hates Joker. Because he does not hate him in all of the interpretations. Not even after he killed Jason. But I didn't really want to bother you with this :) Sorry.
