Empathy is most definitely a very significant aspect of human intelligence, just because it isn't measured in your standard IQ test doesn't mean it isn't. Scoring high on an IQ test doesn't necessarily mean you are very intelligent, it only means you are good at recognizing the type of patterns used in the test.

No rule applies 100% of the time. Understanding that putting good into the world can improve your environment beyond easily identified individual gains is an intelligent concept likely surfacing from group survival, not individual conscious thought.

Imagine you’re born into a world where 1 out of every 100 people is a socio/psychopath and 10 are (to use your terms) less knowledgeable and prone to manipulation of behavior.

Low socioeconomic status is likely to grow for the subset of 10ths that keeps growing exploited under the less ethical influence of the 1s. Low socioeconomic status is linked to having more offspring, which slowly grows the “10s” to higher and higher relative percentage of the population.

Identifying this mechanism and being concerned for the implications as related to life’s adaptation ability, is certainly controversial, but not eugenics. Eugenics is intentional, this hypothetical just a natural process. The thought of people perishing without recourse is the scary part. I never proposed it needed to run its course “because”, just that it might be too late to stop it now. To be eugenics flavored, I argue intent is necessary. Again, not advocating, just acknowledging it may be unavoidable.
