The Joker is a psychopathic mass-murderer and the arch-enemy of Batman, however he is also the love interest of Harley Quinn - who he often abuses quite terribly due to his sociopathic tendencies but has also, on some occassions, shown a degree of affection for (albeit in a way only a madman like The Joker could).
