"An incestuous act of sex at time t" is a descriptive statement of the world which could be able to change the output of a utility function, just as "a scandal at time t + 1 week" or "a deformed baby born at time t + 9 months" could, right? Now, my personal utility function doesn't seem to put any (terminal) value on the first statement either, but if someone else's utility function does, what makes mine "consequentialist" and theirs not?
