Suicide Booth - Star Trek

In the Star Trek episode "A Taste of Armageddon," people who were deemed war casualties by the government of Eminiar VII were required to enter suicide booths. Treaty arrangements require that everyone who is calculated as "dead" in the hypothetical thermonuclear war simulated using computers actually die, without actually damaging any infrastructure. In the end, the computers are destroyed, the war can no longer be calculated in this way, the treaty breaks down, and faced with a real threat, (presumably) peace begins.

After the Heaven's Gate mass suicide event was linked by tabloids to an extreme fascination with science fiction and Star Trek in particular it was noted that multiple episodes, including "A Taste of Armageddon", actually advocated an anti-suicide standpoint as opposed to the viewpoint expressed by the Heaven's Gate group.
