It's very clear to me. He wants to punish Bruce for betraying the League of Shadows, an organization he has dedicated his life too. He is also bitter about how he was exiled from the League despite his dedication while Bruce was given a position as heir and rejected itAnd what's Bane's personal beef with Batman?
Not necessarily. Nothing about the reveal gave off the impression that he's doing it all for Talia.his entire mission is based on a relationship that exists almost entirely off-screen.
Bane did that to strike at the heart of Gotham's morale and rally the prisoners of Blackgate to his side. It doesn't matter if anyone actually believed him because no one was going to stand up and refute him to his face.Bane reading Gordon's letter as if people were just supposed to believe him was odd and had no power.
I.E a country that doesn't actually exist. I never said that wasn't a part of Bane but it's certainly not the most important parthe's from Santa Prisca.
