betrayal and vengeance

His masterpiece 'Oldboy' and 'The Handmaiden' are quintessential explorations of revenge cycles and psychological betrayal that consume both perpetrator and victim.

His Spaghetti Westerns, particularly 'The Good, the Bad and the Ugly,' masterfully portray morally complex characters driven by vengeance, greed, and betrayal in lawless settings.
