Well, in All-Star Batman & Robin we see him realizing he had been wrong and starting to evolve into the father figure,
especially at the end of issue #9.
It looks like Miller was slowly heading this way the whole time,
it would follow the established path of the myth for Robin to humanize Batman,
and take him from solitarily obsessed vigilante to a father figure.
Robin’s whole existence has always been to contrast and temper Batman’s darkness.
It makes sense for Robin to humanize Batman, pull him back from the brink, and vice versa.
There is no consistency in this series. He jumps from an optimistic "Robin Hood"-type (Year One) into a berzerking madman (ASB) into a hard-as-nails-vigilante (DKR).
In each Batman series by Miller we see Batman change. I believe it's the same person and each series are chapters into his life.
