I'm referring to his method in how he deleivered the punishment more ruthlessly than Batman. A trait Batman always seemed to scold Azrael for not tempering his rage.
Yet as the years follows for Batman he seems to develop more of Azrael ruthless punishment upon criminal in the most crippling manner. Its even more apparent in the New 52 when Batman's over zealous physical trauma upon various henchmen's that they form a revenge group. So in the end Azrael's new form of punishment seems to be the strive for Batman, not caring for the consequences of his actions and figuring out new ploys to disfigure a person.
Me I just think writers have went overboard in the how many times can Batman break a person.
