There's religious (Heavean's Gate, that recent kenyan cult), protest (self-immolating monks), media spectacle (Yukio Mishima), honor (seppuku, the samurai ritual mishima was immitating), shame (pompei), escape (L pills) fiancial ruin (1929 brokers), and fads (90s school shooters). Then there's suicide as a way of life (downtown SF, opioid epidemic).
The idea that this is all caused by "suffering" that could be prevented through increasingly sophiaticated treatmant plans or perhaps extended social welfare programs is a peculiar modern secular idea. I wonder if people who believe this sincerely are staving off their own suicide this way.
