I'm certain Bruce Wayne is alive and escaped. Alfred was right next to him so wouldn't kill him as well as commit suicide. His 'Alter ego' Batman is no more AKA dead but he lives on. I'm curious if there's an option not to surrender to scarecrow as you can pick up your items once placed on the table or it that just allows you to continue to free roam?
I don't understand the last part though at 32:15
. Not sure if someone takes his place or its symbolic of his legacy as it mirrors his parents death's. Either way this game's story is amazing and the ending didn't let it down.
