I felt that way too, complete waste of life and lesson. He even bought another pair of the showy shades jack slapped off his face.
Now I'm not even upset he gave up fighting, that's fine. Going in another direction with life is ok too. But he never changed his attitude at all and just worked in that slum forever. At least give him a little hint of having learned some inner peace or something from Jack, even swing the other way and have him trounce a shitty robot in the bar in a dignified manner like jack would have, etc.
