Humans being social animals doesn't detract from the point at all. Here, it's particularly regarding the small subsets that aren't "fit" from a Darwinian perspective. For example a homosexual is unfit because they will almost never reproduce to pass on their genes (adoption doesn't count), and so it would be disadvantageous to the group (again, from a Darwinian perspective) to "waste" any resources (even empathy) on any unfit individuals. Conversely a serial rapist would be very fit as they aggressively seek to pass on their genes.

And we see it playing out globally: as groups become more socially conscious (aka "woke"), their TFR decreases. Just look at a world map showing TFR, and overlay that on one showing "wokeness" by nation. European nations are generally the most woke in the world, and have a generally low TFR. African nations are generally the least woke in the world, and have a comparatively high TFR.
