this is a good theory but you don't even have to look at it as, "each being has the will to destroy everyone". way more likely that it's a natural byproduct of existence that can't be adequately anticipated such that the species can do something about it. We're already on the edge of waiting for the bacteria that can't be killed, the climate disaster that destroys our food supply, etc. (you might say climate disaster is adequately anticipated, but while science is anticipating it, the whole of the species is unfortunately not).
