The point of the entire series was how Bruce birthed the symbol, but then was able to let it go and allow it to pass onto another person. The trilogy's more about the Batman legacy than Bruce himself.
Which is funny because for the first two films in interviews Nolan would say this is Bruce's trilogy more than Batman's. Heck he was saying that in interviews during TDKR's production. It isnt to say it cant do both things, but in hindsight, i wish he had been less concerned with giving us his ending and more concerned with making a great flick.
