I mean, where does being upset or offended come into this?

In evolutionary biology, the F2 (or grandchildren) generation is the more conceptually useful focus point for analyzing the success of various reproductive strategies. Many losses will occur along the way for a wide variety of reasons, some of which are built-in.

Worker ants exist, in great numbers. So do sharks who get eaten by their siblings in the womb. Or sea turtles, alligators and the like who basically start life as snacks and continue to exist only because 1/1000 made it to adulthood. How? There were too many to eat at once.

Genes are genes and individuals are individuals.

If I were a sentient worker ant, would knowing what I am cause a revolution? I think not. Should a sentient baby turtle fall into despair? Wouldn’t be useful.

The vast majority of hominid species that existed are extinct. We’re what’s left, in part by chance. Having a baby is so insanely costly and risky to human women as individuals that given the technology and freedom to avoid it, on average the birth rate falls way below replacement levels. And then on the other extreme Elon Musk has this notion to select all boy children (through IVF, no kidding), who he hopes then will go on to serially impregnate multiple women each, spreading his genes as far as possible. This is also pretty gross. He’ll die at the end of his own life, just like every other person.

So, who are the ‘winners’ versus the sacrificial members of the species here? We each just exist until we don’t. The genes we happen to inherit neither ‘belong’ to us nor define us as individuals. Across generations, life continues on as a massive unguided amoral process, up until it doesn’t.
