In STiD, should Spock have relieved Kirk? In ST09, Kirk relieved Spock of command after the latter realized that the loss of Vulcan had compromised his objectivity. From a plot perspective, this was crucial to getting Kirk into the captain's chair. Back to STiD, Kirk is clearly influenced by Spoiler: events the death of his mentor, Pike. His subsequent decisions to take Marcus at his word and ignore the objections of his crew demonstrate the loss of his objectivity. Of course, plot dictated otherwise.
