Oh come on. Kirk doesn't behave like that on TOS. That's the pop culture cliche of Kirk. He didn't--and doesn't--seduce every woman he encounters, and he certainly doesn't sleep with his subordinates.But wouldn't this oath be for everybody, and more likely so, because of - in all probability - Kirk's antics? Keep in mind, in 79 episodes of TOS, which were repeated regularly, we saw Kirk going at it with any number of ladies across the galaxy - generally hinted at, but "Wink of an Eye" makes it more direct thanks to the commercial break leading into Kirk and Deela putting clothes back on and brushing hair and all. Did 5 years out of the captain's chair really change Kirk so much to become a stickler for the rules? Did he get promoted to Admiral but on the condition he stop banging every wriggling thing in the universe?!
