The Dark Knight Strikes Again/Fridge

Fridge Brilliance

 * Making  a sociopathic killer actually makes sense when you see how he was treated in All Star Batman and Robin.
 * Loops back into Fridge Logic when compared with The Dark Knight Returns, though, where Bruce's internal monologues referencing Dick are vastly softer than Bruce's comments in this book, despite the events Bruce spitefully references predating the previous book.
