What you're arguing here is that humans would not do the right thing. I don't believe that to be true. If there is one thing Star Trek was about, it was about humanity at its finest. While yes, there is a balance between the selfish nature and the common good, in the case of Edith Keeler, there was no choice. She had to die.
Solid observation.
Knowing which side of that argument is right is something a human would have to decide, and as the representation of humanity at its finest, Kirk's judgement would always be perfect. Not that perfection is human, but when it counts, Kirk ALWAYS did the right thing.
...making him the best character in Star Trek franchise history. He had to lead with a blend of his deep, often troubled soul and his mind, even when decisions were against his personal interests--something so many ST characters lacked, as they leaned toward rigid thinking in terms of command, or in other types, were idealized to the point of seeming stagnant and finger-waving (Picard).
In the case of Edith Keeler though, Kirk's personal desires could not measure to the millions of men, women, and children that would die or cease to exist because of his selfishness. Kirk would have had to be a monster to let that happen. It would be borderline insanity, and while love can make you do things you weren't capable of before, it would be as inhuman as possible for Kirk to make the wrong decision.
... and as a result, Kirk would lose his purpose as the heroic lead of a weekly TV series who succeeds, even at great personal cost. any other choice for the character (e.g. Ellison's) shines a light on incredibly out of touch, if not too focused on painting unnecessary negatives someone was despite the established character traits and purpose of the series lead, which were
challenged, but never going to some out-of-nowhere extreme..
I'll give a perfect comparison--Janeway. In Endgame, this woman made the most selfish decision possible, altering a timeline because she didn't like things. Millions of lives altered and changed because of her selfishness. Janeway IS the biggest villain in Star Trek history, and the writers didn't even understand that.
Biggest villain, or just a poor character.
Yes, but none of these humans were Captain Kirk, who represents humanity at its best. The idea of condemning so many millions to die would make Kirk more of a monster than the Nazis themselves. It was a bad call on Ellison's part, and GR rightfully changed that. That would have been very out of character for Kirk.
...and Roddenberry had a boatload of flaws as a creator and person, but his decision here undoubtedly helped turn that episode into an instant classic. Ellison did not--apparently--have any sense of what he was dealing with in the format of characters and situations on Star Trek, considering what he was attempting.
Yes--no doubt. The idea that Edith had to die to save the universe was tremendous writing. The moral dilemma Kirk had to face was worthy of all the praise and discussion. The issue was that Ellison wanted Kirk to make the wrong decision, which would have been very contrary to the character. To make the RIGHT decision in light of all he felt took a level of strength that was worthy of Kirk.
True.
It would introduce time travel for selfish purposes and another moral dilemma. If Kirk can go back and grab Edith, why can't every death be prevented with time travel? Every red shirt that died under Kirk's command could be prevented with time travel.
If the Edith experience taught the Federation one thing--time travel is too dangerous and changing history has unintended consequences.
Its also part of an immature form of writing that has entered the discipline over the past couple of decades where time travel is the answer to everything, consequences be damned. One of its most up-front examples being the
"what the Hell?" attitude toward altering time for personal gain in the all-over-the-place
Back to the Future movies, where key events are just changed (Doc's original death, changing George McFly into a guy who grew a
pair overnight, etc.) or attempts are made to alter said events (Marty's letter, etc.), right up to the ridiculous film
Project Almanac. No set rule has to be followed in time travel fiction, but its better examples (on film) usually had someone painfully aware of their
responsibility to / involvement in the fabric of time to the point where that was not only part of the crisis they faced, but shaped their character, or highlighted something about it at the critical point(s).
