Star Trek: 10 Times Starfleet Officers Crossed The Line

10. Seven Of Nine Condemns A Sentient Being To Death - Prey

While her career in Starfleet may still have been several years away, there was little doubt that Seven Of Nine was an honourary officer aboard Voyager. She was assigned duties like any other officer, she contributed to the smooth running of the ship like any other officer, and she faced the music like one too.

When the ship was boarded by a member of Species 8472 in 2374, Seven found herself face to face with a being who, as part of the retaliatory war against the Borg, had most likely destroyed thousands of drones. 

This being was hunted by the Hirogen - a fearsome Delta Quadrant species who would later capture the ship for their brutal war games - though it had largely managed to evade them. Despite some promising attempts at communication by Tuvok, Seven stepped around the rules and beamed both the creature, and the Hirogen hunting it, onto one of the latter's ships.

Though she attempted to argue her case, Seven was bluntly reprimanded by Captain Janeway. There was a time and place for expressing individuality - but that wasn't it.
