I'm watching TOS all the way through for the first time and finally watched this episode. I was left wondering, did the episode definitively establish that the actor who died at the end of the episode *was* actually Kodos The Executioner? I feel like it did, but I don't think they ever actually clearly stated it and the actor, if he was Kodos, was not the same "person" who committed those atrocities, as he seems to have developed some remorse for his actions over the years and took the......er....phaser for Kirk at the end. Also, Kodos' rationale for what he did reminded me a little of MCU Thanos' misguided rationale for his goals for Titan and for the universe-at-large. Very good/interesting TOS episode.
