When Kirk gave his log entry after leaving Delta Vega, he spoke of Gary Mitchell to Spock: "I want his record to end that way. He didn't ask for what happened to him." Even though Kirk had to kill Mitchell to save his own life (and the lives of others), he still mourned Mitchell's loss.
I remember in Allan Asherman's "Star Trek Compendium", Asherman speculated that Mitchell etched "James R. Kirk" onto the tombstone because maybe Mitchell didn't really know Kirk that well and vice versa, and maybe they weren't as close as they had thought. I just watched that ep again, and I'm not so sure. Maybe Mitchell's attitude showed just how much his transformation had changed his personality.
Another reaction: the uniforms and some of the cast may have been different, but this seems very much to be a TOS ep, in some ways even moreso than other early-first-year outings.
