In "Arena," the Metrons declare the Enterprise
and the Gorn ship "savages" and force them to fight to the death. Kirk goes along with it because he has little other choice.
But suppose Kirk called the Metrons out by saying something along the following: "You say we are 'savages' because we have a right to defend ourselves [from what Kirk saw as a threat], yet you make us fight for your entertainment. That's something only the ancient cultures did. What makes you better than them?"
How do you think the Metrons would have responded?
I personally think the Metrons would agree with what Kirk says, but that they have to proceed because it is the "law of the land." However, I could also imagine them comparing the trespassers to the Metrons' equivalent of cockroaches and deciding to eliminate them as pests.
What does everyone else think?
