Loops back into Fridge Logic when compared with Batman: 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.
Easily explained. In Batman: The Dark Knight Returns, Bruce is regretting his prior treatment with a slightly nostalgic / Old Shame view. In this, after he murdered several friends and brutalized Catgirl, Bruce just let his anger and old hatred out.
Batman claims Arkham degenerated into anarchy and cannibalism five years before DK2. Looked perfectly fine (although staffed by a certain celebrity psychologist) in TDKR, three years back.
That was not the asylum in TDKR. It was "Arkham Home for the Emotionally Disturbed."
