Jack,
don't bother. There can only be two reasons for Turk's behaviour. Either he's just an 8 year old kid or he's simply not that intelligent. It is quite obvious that his world view is limited to say the least and that he's incapable to think in a more complex fashion.
Everything is black and white for this guy, there's no such thing as grey. One is good or one is bad, there's no in between. I was reading an article about it the other day and they said that in some cases intellectual and emotional growth would simply stop due to traumatic events. Even so, one would have to be very averagely intelligent to come up with Turk's assessment of things.
