why does joker have stans? he's a psychopathic murderer and has killed hundreds, if not thousands of people. ( dc database's body count for the joker says it's 559+. )

he's killed jason, crippled barbara, abused harley... just... why???

i've seen and heard people say that they want a relationship like harley and joker. why? just why? joker has always been abusive towards harley. they are the textbook definition of an abusive relationship not "oMg cOuPlE gOaLs!".
