So aside him being a murdering psychopath (or at least that's what all superheroes seem to think), I can't help but think he is a comic book fan who loves DC before the crisis and his way of critiquing the modern DC universe by killing many people. In a indirect unintentional way, isn't he kinda of trying to prove whether pre-crisis heroes or post-crisis heroes are better? These are just my thoughts, anyone can comment as you please.
