I don't think the scene has any special deeper theme or meaning than what we would expect from Kirk or even what has been seen when we see characters in other stories make such decisions. I'm aware of what you feel it has and that's fair enough however. So, while it's there it's nothing especially potent or radically new. Not as it's portrayed in Generations anyway.
