> Death is nothingness, not peace, and pretending like it's preferable is basically acquiescing that infinite nothingness is preferable to nothingness, which is definitionally false.

This seems to be in the realm of philosophy, meta-science and religion. I don't really want to bring the discussion there, but I simply need to point out that many, many religions (and atheists) have different opinions on this matter. For example, a dignified death may bring you closer to the creator (emphasis on "dignified", because suicide doesn't count for some religions).

And I don't believe there's any way to properly gather evidence about what happens to someone after they die. And without establishing our religious ideals as ground rules, I don't think we can really have a good discussion on the matter.
