Returning once more to the ultimate guro setting…

The comment >>15429 said that if tendency to kill oneself if heritable, then it won't work in the long term.

And just the other day it occurred to me: what if we flip it around and say that biology is what's causing it in the first place? Namely, with the life span increased beyond anything that nature indented, that same nature tries to compensate by making kids (or people in general, I'm just focusing on kids because I'm not interested in adult characters) more likely to die. Because humans evolved in the environment with limited resources and deep down the organism can't comprehend that resources are now unlimited and there's no need to fight the overpopulation. And maybe it happened to be such a fundamental thing that fixing it with genetic engineering was orders of magnitude harder than life extension that caused it. So at first they just accepted it as a side effect. In fact, maybe, at least at first, the resources were just unlimited enough to support feeding children until they kill themselves, but not so unlimited to let everyone live their full extended lifetime, so whatever biological mechanism made kids start killing themselves was not wrong. And then maybe eventually solutions were found, both in regards to the economy becoming even more prosperous and the biological mechanism identified and possible to be fixed… but at that point everyone just got so used to it they couldn't imagine living without it. After all, seeing kids kill themselves is so fun! Being a kid and killing oneself is so fun! Adults were kids once too and remember how the idea of killing themselves sounded like fun and they only didn't to it themselves because somehow it never got to it and now they're just to old for that… but they definitely wouldn't want to take such fun away from their own kids! Right?
