Kirk makes this remark about having paid with their "own blood" but it never seems to occur to him that he is partially responsible for that.
A perfect example of the leadership by arrogance approach that he displays throughout the films, beginning with his behavior in TMP. He accuses Scotty of incompetence by asking why the transporters haven't been fixed and takes him to task for whining about the change in the
Enterprise's orders and launch date. He then ousts Captain Decker from command despite knowing nothing about the designs of the refurbished
Enterprise, a vessel that Decker played a significant role in both redesigning and rebuilding. The end result is his flying the
Enterprise into a wormhole that nearly ends with the ship severely damaged by an asteroid. His mistakes stop only after McCoy calls him out and Spock arrives to help Scott repair the engines.
In TWOK, he assumes command of
Enterprise and promptly ignores the warnings of a bridge officer when
Reliant doesn't immediately answer hails. The ship is crippled almost beyond repair and several cadets and officers are injured or killed. Kirk never apologizes to Scotty for getting his nephew killed, nor does he apologize to Spock for wrecking
his ship. When Spock later sacrifices himself to save the
Enterprise, Kirk admits that he "knows nothing," but apparently forgets this lesson by the time of TSFS.
He tells Sarek that he would have sacrificed himself to save Spock, but if that's true, why didn't he try to repair the conduit himself? Granted, it seems as though he didn't realize where Spock had gone until Bones called the bridge. But it's not as though he needed to be on the bridge while the
Enterprise was trying to leave the nebula. Sulu could have taken the ship to warp without him, as he'd already given the order ("Get us out of here! Best possible speed!"). Why not atone for his mistakes by not asking another crew member to die in his place? If he'd acted properly following Saavik's warning, Khan would likely have never gotten his hands on Genesis, and perhaps no one would have died.
And what about Terrell, who seemed like a good man caught up in situation he didn't really understand? Did Kirk grieve for his death as he did Spock? If he'd handled things differently, perhaps Terrell would still have been alive at the end of TWOK and could have resumed his career, albeit following a hearing of some sort. Captain Esteban and the
Grissom? Would they have died had they not been at Genesis? And so on, and so on.
