Our culture teaches children that animals are there to serve us, even to the point of hurting them (food, medical research, hunting, etc). I believe compassion is something that can be taught to children, but I think our culture and many families within it tend to teach cruelty instead. And most of us aren’t capabable of the self reflection needed to change our disposition in regards to empathy until the prefrontal cortex develops.
Environmental factors, many of which capitalism produces as negative externalities, affect how the prefrontal cortex develops in addition to how it socializes us towards antisocial behavior. To name some of the less obvious factors: trauma, substance use, and financial stress/insecurity.
Additionally, the gene expression for anti-social behavior surely is adapted to turn on when most beneficial to the survival of the organism.
I don’t have a study handy as most of this is stuff I learned taking human services classes. I can look for a paper on nature vs nurture and antisocial behavior specifically if you’d like. Or epigenetics and antisocial behavior. If my comment wasn’t enough.
