Death sentence

"Death sentence" and "death penalty" were common names for the capital punishment of execution — the state-sanctioned death of an individual for crimes of an especially grave nature, such as murder or treason. Sometimes, especially in Earth's past, or in places without clear governmental structures, it could be carried out against people for less profound crimes, or even for no substantive reason at all.

Earth
On Earth, it was a divisive issue. Some people, such as the Briton, Professor Kettering, believed that the death penalty was a backwards conception of justice. (DW: The Mind of Evil) To the contrary, many Americans in Jacksonville, Kentucky on "Miracle Day" fully believed that the rapist and murderer Oswald Danes should not have been paroled after his death by lethal injection failed. (TW: The New World)

Indeed, there was a general divide between the British and American viewpoints on the issue. The death penalty was abolished in the United Kingdom at least by the late 20th century, whereas it was still an acceptable punishment in at least the state of Kentucky as late as the year 2011.

Elsewhere
Elsewhere in the universe, the death penalty was known to be used by the Raxacoricofallapatorians. The Slitheen family, for instance, were tried and sentenced to death in absentia. The Ninth Doctor, who had captured Blon Fel-Fotch in Cardiff and wanted to extradite her back to Raxacoricofallapatorius, was faced with the moral dilemma of whether he could become, in effect, her executioner. (DW: Boom Town) Later, in 2009, members of the Slitheen-Blathereen family apprehended two other Slitheen, teleporting them on board their ship to send to Raxacoricofallapatorius for execution. Other members of the Slitheen were said to have been "brought to justice". (SJA: The Gift)

Time Lords exercised the death penalty, largely for crimes against the Laws of Time. The penalty for setting oneself up as a god in a more primitive civilisation, for instance, was vapourisation. (BFA: False Gods) The death penalty on Gallifrey was sometimes effected through a "Warrant of Termination". One was served on the Fifth Doctor. In that instance, however, he wasn't threatened with death because of any actual wrongdoing, but because he had become controlled by a malevolent entity that posed a grave risk to the entire universe.
