Warning: This article contains spoilers for The Batman.
The Batman presents Robert Pattinson's version of the Caped Crusader with only two years of experience under his belt, but even as a great detective, there's one crime he should never solve. As crime thrives in Gotham City, Batman attempts to make a difference wherever he can. Unfortunately, Bruce Wayne discovers his own family is caught in the same web of corruption he's trying to stop.
It's nearly always canon that Bruce Wayne becomes Batman due to the trauma of losing his parents at the hands of a gunman. Afterward, Bruce would turn his attention to fighting crime. In The Batman, he uses the Dark Knight persona to seek vengeance against all corruption in Gotham. However, the critical thing to note is that the mystery of who killed Bruce Wayne's parents remained.
Bruce Wayne should not yet learn the truth of his parents' killing for two reasons. The first reason is that it could jeopardize his identity as Batman. Bruce resigns to fighting as much crime in Gotham as possible because he doesn't know the identity of the criminal who killed his parents. For him, any criminal could have been responsible for his parents' death. With that level of obscurity, Bruce Wayne has an almost never-ending purpose in being Batman. Thus, it's essential for Batman not to solve the murder of Thomas and Martha Wayne for the time being. If Bruce knew the culprit, there would be an increased risk of him no longer wanting to be Batman after seeking out revenge.
In The Batman, Bruce Wayne learns that Thomas and Martha Wayne's murder is connected to an infamous mobster in Gotham. Bruce believes that the crime boss may have been responsible for the killing. Upon learning this, Bruce is insistent on confirming the truth. Although, he later discovers that the actual perpetrator of his parents' murder is still unknown. That instance demonstrates how fragile the truth was for Bruce. It's possible that if he confirms the mob boss directly responsible for his parents' murder, then Bruce would exact his vengeance on the criminal. Whichever way that encounter might end, Bruce could inevitably have to deal with his grief and trauma.
The second reason Robert Pattinson's Batman shouldn't solve his parents' case is that it's too soon for him to know the truth. Robert Pattinson's Batman has only been Batman for two years, and his identity as the Caped Crusader is too fragile. In most iterations of Batman's stories, he does eventually discover the murderer of his parents, but only after many years of fighting crime. The difference of time can play a factor in how Bruce reconciles the need to continue being Batman. Rather than simply using Batman as a means of vengeance, he could discover that the city needs Batman regardless of Bruce's issues.
Robert Pattinson's Batman still has plenty of room for growth. The Batman lays an excellent foundation for viewers to understand the early motivations of Bruce Wayne and a glimpse of how fallen the city of Gotham has become. Bruce Wayne may eventually crack the case of his parents' death, and he could find new reasons to remain being Batman too. Maybe one of those reasons is to prevent another young child from losing their parent to senseless crime. For Pattinson's Batman, by chasing the never-ending crime in Gotham, he could eventually discover a higher calling for being the Dark Knight. However, for now, it would make more sense for the murder of the Wayne parents to remain a mystery.
