Survival is Insufficient
In "Survival Instinct" from "Star Trek: Voyager," Seven of Nine is faced with a choice - send three individuals back to the Borg or sever the link between them, knowing that each will only have a couple weeks or so to live. She chooses to terminate the link, but the Doctor questions her motivations, asking if this isn't about her guilt for having caused the situation in the first place, and also noting that he has a duty not to harm his patients. She explains that "Survival is insufficient," that she wishes for them to experience individuality as she has, and as she explains, as the Doctor has too. The Doctor is forced to agree that "Survival is insufficient."
Living is More Than Surviving
