In the new joker movie, they should make it have a dark and dangerous tone.

For example, somebody should say to the Joker: "do you like happiness and being good?" And the Joker should say: "No! I like the opposite!"

Also there should be swearing such as "fuck" for example.

@peptostate I don't know about this. What you're describing sounds very adult, and the Joker is a character for kids
@peptostate this says a lot about are society 
@peptostate 'fuck' is too rude. I propose they substitute it for 'heck'.
@peptostate as someone who likes happiness and being good i do not think i would enjoy this movie
