Although horrific, this does not match the horror of the grief eating away at Logan, now a holed-away alcoholic limo driver who will clearly meet his end soon. His healing powers are degenerating and valleys of age are carved in his face.
The movie’s central question is not which bad guy Logan has to take down, but instead: what is Logan reckoning with? What is the nature of his suffering?
Logan’s character arc overlaps with many aspects of Jungian psychology, namely the process of individuation and harmonizing our “shadow” selves with what we project to the world, our “persona.”
