Grossman argues that there is an innate resistance to killing members of one’s own species. Do you agree with his theory? Why or why not?

Given the innate resistance to killing, what factors enable atrocities to take place? How, for example, does Grossman explain the My Lai massacre in the Vietnam War? Are there any other possible factors not included in his analysis?

How does the military invoke classical and operant conditioning to train soldiers to kill? Is Grossman correct to draw an analogy with the impact of violent media on modern youth? Why or why not?
