Nature has a way of ‘culling’ members of a species.
Lemmings overproduce. When their population gets too high they race to find another habitat; falling off cliffs, drowning in large bodies of water, etc. thus cutting their numbers.
People have a similar kind of ‘suicidal’ proclivity, although they don’t realise it.
There are groups which refuse vaccination, which leads to death. This is good as these groups are unnecessary.
Today there are those who dismiss Covid-19 as a ‘hoax’ which helps to cull populations.
A demagogue, who has an excess population, convinces his followers that a pandemic doesn’t exist. This enables them to can catch the disease, die and make resources available to the more intelligent and useful.
Every hundred years, or so, there is a ‘plague’ and millions of stupid people die.
It is survival of the fittest. The intelligent, those who only take their information from reliable sources and are immune to the stupidity spouted by fools, will live. The stupid will die.
