I do sometimes fantasize about a sudden disaster, whether it is natural or man-made to wipe us out on a whim so we all wouldn't suffer anymore. However, realistically, I don't think that is likely to happen in the immediate future (unless a series of major shit events happen back to back to back on a large scale), but in the late future (like many years from now).
In regards to suicide prevention becoming more and more aggressive, it seems like the pro-lifers are onto something. They probably have some sense that people are getting smarter and are getting more sophisticated at escaping life so they double down and even go to such extreme measures to keep us tied to this hellish rock. It's as if they deliberately want us to suffer with them until the (inevitable, natural) end.
