I think therapy is a place where we get to decide our own morals. The therapist's morals should not come into play.

Obviously, when it comes to things that could harm the client or others, the therapist has a duty to intervene, or at least offer a different perspective.

Conversely, I do not think the client should try to impose their morals on the therapist. In fact, therapy is a place to examine long held beliefs and if those beliefs are contributing to the quality of your life.

Obviously I am not big on moralism. I think it's all relative. I'm just not into absolute anything.
