'the enemy within'

There's an episode from the first season of Classic Trek where a transporter malfunction splits Kirk into two halves. The first half contains all his nobler characteristics: gentle manner, restraint, compassionate, friendly and so on -- but as the sheep, it is incapable of command and making decisions. The second is his "dark" half: self-indulgent, brutal, violent and incapable of control. Call it the Wolf. The Wolf attacks a crew member and even tries to rape Yeoman Janice Rand.

The episode's quite interesting from a psychological perspective, and it's even been used to assist some psychiatrict patients by getting them to see that both sides of their personality are essential for them to be a fully functioning human being.

Now at the end of the episode, when they fixed the transporter and reintegrated the two halves of Kirk, he remarks to Spock, "I've seen a side of me no one should have to see." I think we're led to consider the Sheep to be the real Kirk since it's the one we see at the start of the episode, and so we understand that he's referring to the Wolf.

I'd argue that he's also referring to the Sheep -- that he holds the interal weakness in his much disdain as the internal predator.

Any takers?
