I mean he invests time and money into designing this persona and building the Batcave (which we never really satisfactorily see) all for it... To not really be used? Really the set-up of the Batman "universe" in the first two movies was a big cock-tease only for it to be pulled out at the last minute with this movie with the Batman idea never really taking off.
It's inherited by Blake, cave and all.
Whatever happens on earth, that up there, that's the endgame.
