If you followed the comics then you'd know that DC characters have no character outside of the hero.
Prior to the 90s Batman was not the haunted hate filled character modeled today.
Uh, Sergeant Rock comes immediately to mind, along with most of Easy Company. They were also big in the horror and western genres before the CCA was established.
And Batman started as dark and hate filled. Hell, when he started he had a gun and shot criminals! It was only when the CCA was created that he changed, and his "code against killing" developed. But that was not the original character, he was created more in the mold of The Bat and The Shadow, and had no problem using guns or killing people.

Batman #1, Spring 1940
Oh, and the "Dark Knight" is a throwback to that, and the inspiration to the Batman 1990 movie. But that was not 1990s, Frank Miller's The Dark Knight was in 1986. Gotham City was dystopian (it was the 1980s, Dystopian futures were big) and he was returning to his more violent roots and not working with the cops as he did for the previous decades.
Actually, I have been following comics for decades. Having read the Golden Age and Silver Age originals. Even remembering the original Joker origin as The Red Hood (1951). Hell, I still laugh at the "kids" that think that Spider-Man's black outfit came from either a meteor (movie), or Madame Web (tv cartoon).
