What term describes someone who is self-righteous or hypocritically moralistic?

The term that describes someone who is self-righteous or hypocritically moralistic is "sanctimonious." This word implies a sense of moral superiority, where an individual often portrays themselves as being more virtuous or morally upright than others, usually in a way that lacks genuine sincerity. A sanctimonious person might emphasize their own beliefs or behaviors while critiquing and judging those of others, thereby revealing a level of hypocrisy in their moral stance.

On the other hand, "skeptical" relates to doubt and questioning, typically towards claims or ideas, which does not align with the concept of moral superiority. "Secular" pertains to things that are not religious, and it does not convey anything about one's moral character. "Satiate" means to satisfy, particularly in terms of appetite or desire, and does not connect to moral or ethical behavior. Thus, "sanctimonious" is the term that accurately describes the trait of being self-righteous or hypocritically moralistic.
