I think the following panel which is from Miller’s recent work on one of the two characters (the other been one of the more notably Catholic superheros in comics Daredevil) he is most associated with may illustrate something about how his mindset has changed over the years. The panel below is from the last few years:-
Now these are comic books ultimately and I’ve never yet read a superhero comic book that even I die hard fan of the genre would call a literary masterpiece. That said like anything else there are varying levels of quality. Here’s Miller’s work on the same character 20 plus years ago:-
And Miller handling the aforementioned Catholic superhero Daredevil:-
This is a writer whos abilitiy to deal with the nuances of human beings and how they relate to each other seems to have sadly decayed. Whereas his compatriots who were feted at the time seem to have maintained a more positive view of human nature and potential Miller seems to have become very, very cynical and pessimistic as he has aged. I have no problem with dark heroes but heroes who are violent merely for the sake of it or who have rough sex with barmaids in costume and who beat up policemen because it’s ‘fun’ are not characters who are anti-heroes they are villains.
