Murder
Murder was a criminal offence involving the deliberate killing of one or more individuals.[source needed]
Murdering a being could result in numerous penalties. Common ones were life imprisonment and execution. (TV: The New World) Killing beings on a battlefield did not usually count as murder. (TV: The Caretaker) A killing classified as murder usually meant it was a targeted attack on a single individual. Serial killers would target multiple people over a period of time. (TV: They Keep Killing Suzie) Murder of an entire race was called genocide. It was one of the most serious crimes in the universe. (TV: Evolution of the Daleks, The Doctor's Daughter, Journey's End)
In the 51st century, murder was seen in a less serious light. Unlike most cultures around the 21st century, murder was considered an addiction like drugs and alcohol and instead of a death penalty or imprisonment, the murderers would be sent to rehab. (TV: Kiss Kiss, Bang Bang)
Morality
The Seventh Doctor felt that, fundamentally, the only argument against murder that could stand up was utilitarian: "we don't [ourselves] want to get murdered." (PROSE: Original Sin)
"In the end, Pryce was right. There is no reason why one person should not kill another. No argument against murder stands up to scrutiny. For every religious prohibition saying, "Thou shalt not kill", there's another one that allows killing under certain special circumstances – sinners are fair game, "Thou shalt not suffer a witch to live", and so on. Moral codes are no better; they're just formalised opinions, without any logical backup. The sociological history of almost every race is riddled with examples of laws against murder standing beside legalized examples of murder, be they executions, wars or euthanasia. Ultimately, every single argument that we can come up with, stripped of its pretty words, boils down to a fundamental truth: we disagree with murder because we don't want to be murdered. No more and no less than that."
The Doctor
The Doctor himself often battled over whether he "had the right", to take another person's life, even toward altruistic ends. (TV: Genesis of the Daleks, The Parting of the Ways, The Witch's Familiar[additional sources needed]) In some cases, he took this option. (TV: The Wheel in Space, State of Decay, The Two Doctors, Dinosaurs on a Spaceship, Deep Breath, COMIC: Terrorformer)
The Doctor counted the number of children on Gallifrey that died at the end of the Time War, when he destroyed the planet. The Tenth Doctor knew this number well, as 2.47 billion, but by his eleventh incarnation, he had forgotten this. The Eleventh Doctor expressed that he "moved on." (TV: The Day of the Doctor)
By his twelfth incarnation, the Doctor did not keep track of how many people he had killed, as he felt the need to move on and save other people's lives outweighed an obligation to honour those he had failed. (TV: Thin Ice)
"There are situations when the options available are limited. Sometimes the choices are very ..."
