Edwarrd Nashton was an orphaned like Bruce, except he was forced to remain in an impoverished orphanage where children died every cold season, whereas Bruce Wayne grew up wealthy in Wayne Tower. To compound it off, Bruce did nothing to help the community, something that Gotham's city's president blames him of. The overarching theme of the picture is revenge, as both Batman and Riddler want retribution against the city that mistreated them – though they were victimized in various ways.

For Bruce, Gotham and its crooked leaders, police officers, and lawbreakers had to pony up for his parents' mass killings — and whether it was his original purpose or not, Bruce sought to carry on his family's legacy because Thomas couldn't — whereas Riddler wished the same users to pay for neglecting him, individually, after he had been made an abandoned child — not before, as was the instance for Bruce. As kids, they both experienced a sense of hopelessness that pushed them into becoming who they really are as The Batman.

However, as a result of Riddler's deeds and charges against Bruce Wayne as a human, Batman's vengeance is replaced by hope. It's why he reaches out to Gotham's mayor both physically and figuratively within the arena, not just to save and preserve her, but also to serve as a beacon of light for the citizens of Gotham, a true symbol of light. The Batsignal instilled terror in criminals at the start of the film, and while this is still true at the end, it has now spread to everyone else. Batman had a lasting impact on the city, and his parents could be pleased of it.
