tw for mention of mental illnesses
"The Joker (or Arthur) appears to have a complex mix of diagnoses, including pseudobulbar affect – a rare condition consisting of uncontrollable laugher or crying, and possibly a psychotic illness, evidenced by his apparent hallucinations about the subject of his affections (played by Zazie Beetz). In addition, he displays features of certain personality traits that are not technically considered to be mental illnesses – psychopathy (he feels no empathy for the victims of his violence) and narcissism (which makes him crave attention and adulation by any means necessary)."
literally all the men who have played joker had to go crazy.
