When I was watching Obsession (TOS-R) the other day, I noticed just how close Kirk came to having a "Matt Decker" moment as the Enterprise was chasing the Cloud Creature. It was incredible how close the situations mirrored each other. A pair of starship captains acting recklessly chasing revenge. Both retreating at the last second when they realize the chase may cost them command. I think this is the reason Jim Kirk is my favorite character in all of Star Trek. He is a very human character and not that far removed from the likes of Decker or Ron Tracy (The Omega Glory) and could easily go down the same path given the right circumstances.
