I’m convinced that while everything about the Joker- his murderous instincts, his maniacal laughter, his maddening behaviour- points to him being insane, he is the farthest thing from it. The Jokers greatest prank has been to pull the wool over society’s eyes all these years, masquerading as a madman so as to be thrown into an asylum and treated with kid gloves when apprehended, to be ‘rehabilitated’ rather than punished in a penitentiary. It’s a strategy worthy of a high-stakes player, so it’s apt that he’d be named for a playing card
