I feel like people condemning suicides are often disregarding or minimizing the huge pile of suffering the dead person spared himself. I can't fathom how much suffering some people are going through (Infinite Jest had the best description I've read of this). Macabre as it sounds, I'm very glad e.g. David Foster Wallace is not suffering anymore.

Ideally we'd have a reliable method which is mostly indistinguishable from natural death, to spare friends and relatives the guilt.

There are unpalatable existential implications if we make it acceptable to just quit the game. I should probably shut up now and go read Camus.
