"Quite inadvertently, the British gas conversion proved that the incidence of suicide across an entire society could be radically reduced, upending the conventional wisdom about suicide in the process.
At least a partial answer is that many of those Britons who asphyxiated themselves did so impulsively. In a moment of deep despair or rage or sadness, they turned to what was easy and quick and deadly — “the execution chamber in everyone’s kitchen,” as one psychologist described it — and that instrument allowed little time for second thoughts. Remove it, and the process slowed down; it allowed time for the dark passion to pass."

What united all the survivors I spoke with was a sense of having been so utterly transformed by their experiences that, in essence, they had become different people.

Most do not want to die; they simply want the pain to go away and act impulsively to end it.
What I find fascinating about this article are the survivors reaction to the act of suicide. They immediately know what they did was wrong and want to take it back.
