When he was first introduced in comics, Batman was a grim and vengeful figure.

At the time, Batman didn’t seem to have a straightforward code as he fought crime. He even wielded a pistol, indicating that he wasn’t opposed to taking lives if necessary.

Although fans noticed the changes, they were never explained canonically. As comic book writer and artist Darwyn Cooke bridged the gap between the Golden and the Silver Ages of the DC Universe in DC: The New Frontier, he took the opportunity to elaborate on Batman’s changing public image.
