The clown is a madman and a mental derangement, so what he said in The Dark Knight is just his own fantasy, which makes the other person feel scared.
The reason why the screenwriter of this film will design such a plot that has nothing to do with the original comic book is to show the darkness, abnormality and psychological distortion of the clown.
And the real clown, he became like that because of Batman, which is why he has a hard time with Batman.
The clown in the original cartoon is a clown with green hair, pale face and a big mouth, much like a clown in a circus, hence the name clown. The clown's real name is Jack, and he is one of the murderers of Bruce Wayne's parents. Later, when Jack changed from a punk to a gangster, Batman was born. In the process of being chased by Batman, I accidentally fell into the chemical pool and became like this. For details of this story, please watch Batman 1 filmed in 1989.
The above is the relevant answer about the clown, I hope the landlord is satisfied.
