Building off of your other answer here, I think I can imagine at least one situation where your terminal values will get vetoed. Imagine that you discovered, to your horror, that all of your actions up until now have been subconsciously motivated to bring about doomsday. Causing the death of everyone is actually your terminal goal, which you were ignorant of. Furthermore, your subconsciously motivated actions actually have been effective at bringing the world closer and closer to its demise. Your only way to divert this now is to throw yourself immediately out of the window to your death, thereby averting your own terminal goal.
Would you do this?
Dr. Jekyll and Mr. Hyde are the same person, but are they really the same agent?
True, it’s hard, but it does happen. As evidenced by the many of us who actually have become apostates of our native religions. After becoming convinced that the central thesis of the faith was in error, the jig was up.
EDIT: I think your way of phrasing it is descriptively the most accurate, because it’s psychologically quite possible to resist the act of apostasy despite not actually believing in the truth of your own beliefs. However, for many of us, we would consider such a person a non-believer and hence a de facto apostate, even if they didn’t think of themselves that way.
