A worthwhile therapist would never try to change your moral or ethical belief system in therapy.
However, therapy may be a challenge if you really do believe that your way is the only way to look at the world. Therapists attempt to help people change the way they perceive things.
Almost everything is neutral, there is no one thing in the world that everyone is afraid of, and there is no one thing in the world that everyone loves. However, there are many perceptions about everything.
Take an elevator, for example. Let’s say that standing in front of an elevator are a four-year-old girl who loves to push buttons and her fifty-year-old grandfather, who has an elevator phobia.
When the doors open, the girl will want to run in and push the buttons, whereas her grandfather will not want to get in. How can the elevator be both fun (for the girl) and frightening (for the grandfather) at the same time?
Well, the elevator is really neither fun nor frightening. It is a neutral object and purely subject to the perception or opinion of anyone who interacts with it.
So, therapists will try to work with you to change the way you perceive certain things, but they will not tell you that you need to modify your ethical code.
