I am convinced that Alfred is fully complicit.

Not only in aiding and abetting Bruce's vigilante alter-ego, but encouraging him to become Batman.

He didn't take the boy to therapy, he apparently taught him to release his stress with violence, and he instilled in him that the Wayne legacy was to improve Gotham's standard of living whatever the cost.

Alfred may not have known he was raising a Bat-man, but he definitely raised a violent fanatic with delusions of altruism.
