Batman once again becomes a member of the Justice League during Grant Morrison's 1996 relaunch of the series, titled JLA. During this time, Gotham City faces catastrophe in the decade's closing crossover arc. In 1998's "Cataclysm" storyline, Gotham City is devastated by an earthquake and ultimately cut off from the United States. Deprived of many of his technological resources, Batman fights to reclaim the city from legions of gangs during 1999's "No Man's Land".
In my opinion, one thing that makes Batman so easy to relate to is the fact that he's human, and he doesn't have any powers. He gains the victory over most his adversaries through tactics and smarts. On the other hand, compare this to Superman. While he does have flaws, he's a lot less easy to relate to because he's nearly invulnerable, and only has one true weakness.
Batman is often treated as a vigilante by other characters in his stories. Frank Miller views the character as "a dionysian figure, a force for anarchy that imposes an individual order". Dressed as a bat, Batman deliberately cultivates a frightening persona in order to aid him in crime-fighting, a fear that originates from the criminals' own guilty conscience. Miller is often credited with reintroducing anti-heroic traits into Batman's characterization, such as his brooding personality, willingness to use violence and torture, and increasingly alienated behavior. Batman, shortly a year after his debut and the introduction of Robin, was changed in 1940 after DC editor Whitney Ellsworth felt the character would be tainted by his lethal methods and DC established their own ethical code, subsequently he was retconned as having a stringent moral code. Miller's Batman was closer to the original pre-Robin version, who was willing to kill criminals if necessary.
