"Good" and "Bad" are very situational, aren't they?
I'm thinking more of traits, proclivities. Some are born with none, some born with them very strong. These traits are defined as good and bad by current societal norms. In ancient Greece pederasty was a norm. In current times, taboo.
I think there are more traits inbred than we would define as abnormal. Violence/nonviolence, empathy, sympathy, submissiveness/aggressiveness.
