Absolutely. That's pretty much what therapy is supposed to be about - letting the client understand what is going on. That would usually lead to a greater understanding of other people's points of view, I would imagine. Some therapists do therapy based on, for instance, a particular religious POV, and for some clients that is the ideal kind of therapy, but the majority of therapists are presumably supposed to be neutral in terms of values and morals. A T is supposed to help the client discover what is that client's morality and values. I'm sure that many Ts encounter clients who are just so different in terms of their morality that they find it difficult to work with them. The professional thing to do then would be to refer them to somebody else. All Ts are not that professional, but it is to be hoped that most would be.

I sometimes wonder what it must be like to be a treatment provider in prison, doing therapy with criminals who have committed atrocious acts. That must really take it out of the T, unless they disconnect their own selves completely.
