> I happened to have a series of genetic alleles, "warrior genes," that had to do with serotonin and were thought to be at risk for aggression, violence, and low emotional and interpersonal empathy-if you're raised in an abusive environment. I worry that violence breeds violence, literally. What will happen to kids growing up in Syria today, where effectively mass abuse takes place (unless different kinds of abuse have different effects)? What will happen to kids growing up in the U.S. and Europe today, where they experience the constant bombardment of hate, either by observation, participation, or as victims of it? EDIT: How many extra abusers are we creating in the next generation, who can pass it down to their kids, etc. ... On the hopeful side, violence has decreased in the world over time; we can make make progress if we want to.
