Yes, I do think that morals need to be taught. Why are children not as efficient as adults when thinking through behavior choices in regards to consequences? Why are they not as able to resist temptation? I'm pretty sure the answer to that is because their prefrontal cortex doesn't mature until they are older.
If morality is nature as opposed to nurture, why are morals so different amongst cultures? Yep, a very difficult question.
I think it is pretty clear that a brain injury of some sort, prefrontal lesions, perhaps, or a lack of dopamine, norepinephrine or a myriad of other things allow a person to deviate from social norms without qualms.

Let me know what thoughts I am missing.
