PTSD, rationalization and compartmentalization

In the past few minutes of listening to Five Finger Death Punch I've begun wondering about the desired end result of the psychiatric treatment of PTSD.
Do they want their diagnosed patients to compartmentalize their experiences and move on or to justify and rationalize their actions to allow them to return to society?
Thus I pose these two questions:

1. If rationalization is desired what would occur if you held a single psychiatric patient in a natural setting with minimal interaction with a psychologist, and an objective to simply ponder their own actions/memories in relation to the natural world (just to talk about the subject's progress and discoveries) how would they react? Would they return to a baseline behavioral pattern through natural stimuli and reset to their own internal instinctual systems? Or would it simply reinforce antisocial behavior and close them off to external support systems?

2. If compartmentalization is desired couldn't you compile environmental stimuli that indicate whatever threat(s) that produced that case of PTSD and create a new conditioned response to parallel stimuli or produce new enjoyable impressions to corollary stimuli? Would that allow them to cope with their detrimental conditioned shock responses and interact within societal norms? Or would it cause them to compound upon their own negative reactions and open up even more complex problems?
