Some further thoughts on the film themes, as well:
I think the movie did a great job to demonstrate that even if you actually are well intentioned, you still need to take care and do good things in a very well thought manner, otherwise, the system will just crush you eventually, just like Thomas and Martha were actually trying to do a good thing donating the Wayne Manor for orphanage and opening the billion dollar Renewal for the disavatadged, but were eventually trapped and their deeds exploited or how Bruce is confused if is he having any effect by the beginning of the movie, depicting of how a person he saves is totally afraid of him and how, by the end, he notices his means inspired Riddler and others alike - much like the dude unsmaked that also goes "I'm vengeance". Then coming to understand that, yes it's necessary to be Batman, but as a symbol of hope.
It's very meaningful, paying a closer attention that the first thing Alfred questions is Bruce leaving aside his family's legacy, to which he says [helping ppl in this manner] he is doing his family's legacy just fine.
Then further ahead in the movie, you realise if he had better paid attention to his duties as Bruce Wayne, he'd have inspected the Renewal to not let it reach such situation or the orphanage to not get into such a state of abandon and desrepair. His Wayne side, just as Alfred points as the very first thing in the movie, was more meaningful than he comprehended.
