Eh, Alfred was a butler. A gentleman's gentleman. I don't see why they can't just let characters be themselves without turning them into action heroes.
You're not listening. In the comics, Alfred Pennyworth was and is a former British intelligence agent and combat medic
who later became an actor and then
eventually became the Waynes' butler. This is canon. He's not just
a butler, but has many hidden skills that are of invaluable aid to a crimefighter. This has been an established part of the character's history in the comics for at least three decades (as far as I can track down). What we're seeing in this show is arguably less
revisionist than what we've seen in earlier shows and films that ignored Alfred's intelligence background.
