Which Christopher Nolan Character Has the Most Morally Uncomfortable Journey?

J. Robert Oppenheimer (Oppenheimer) -- Built the bomb, changed the world, then lived in its shadow. Existential guilt in human form.

Harvey Dent (The Dark Knight) -- Went from white knight to burned-out coin flipper. Justice was never this messy.

Robert Angier (The Prestige) -- Clones himself, drowns himself, applauds himself. Magic has never been this ethically complicated.

Leonard Shelby (Memento) -- No memory, no mercy. Just a well-crafted lie on repeat.

Cooper (Interstellar) -- Left his kids for humanity. Came back when they were older than him. Oops...

Bruce Wayne (The Dark Knight Trilogy) -- Traumatized billionaire punches poor people at night. But, y’know, for justice.

Dom Cobb – Inception -- Breaks into dreams, bends minds, blurs reality — mostly to deal with his wife issues.

The Protagonist (Tenet) -- Saves the world backward. Doesn’t know why. Still cool with it.

Alfred Borden (The Prestige) -- Lives half a life. Shares a soul. For the ultimate magic trick? Definitely not healthy.
