One of the greatest episodes of Deep Space Nine (1992–99), “In the Pale Moonlight,” is entirely about how, in times of crisis, moral compromise may be necessary, even for Starfleet. But such cases are treated as exceptional, unusual circumstances far beyond the norm; as a rule, Starfleet is good, and the best way to be a good servant of the true and just in the world of Star Trek is by being a good Starfleet officer. How does one be a good Starfleet officer? By doing one’s job, by being a professional, by following one’s duty.
