Who is the antagonist in story The Lady or Tiger?

The antagonist in "The Lady or the Tiger" is never explicitly named or directly revealed. Rather, the antagonist takes the form of an overarching oppressive or authoritarian system represented by the king and his court. They hold power over the protagonist, the young man forced to choose between two doors—one leading to a hungry tiger, and the other to a beautiful woman—without knowing what lies behind each. The antagonist in the story is, therefore, the arbitrary and unfair nature of the decision that the protagonist is forced to make.
