OK, so here's a way out of the "circle:"
for those who OBJECT to what nuKirk did, what SPECIFIC differences would you include in the scene
What should he have done?
-not fired at all(perhaps have the movie make clear that the ship was going to be destroyed FOR SURE, 100%?)
- repeatedly beg Nero to pretty please surrender with a cherry on top?
-have NuKirk try to beam over to the Narada and drag Nero bodily to transport him away?
-have nuKirk show more regret at the situation?
Perhaps extract Nero's promise that he will never again attack the Earth and try to kill all her peoples. Making sure that his fingers aren't crossed behind his back.
He must apologize, or no dice!
