This is a problem with how characters around the DCU are depicted, not Batman.
As I wrote in an earlier post, violent crime in the real world is down significantly in the US since the 50s and 60s, but comics have gone full bore in the opposite direction. This is made worse by the reality that the use of police force has become a contentious topic. Ramping up both the violence of criminals and the superhero response to it is bizarre and dissonant.
