It is a matter of focus. Take any situation and first you must describe the problem and then who is facing it. In our recent examples we discuss the army recruits and the prison wardens (the killers as Paul puts it). Paul argues that whatever their circumstance, each person must individually make a choice that may in the future lead to killing and it is this choice that lays blame on them. I agree that each person must make the choice, and to some degree be held responsible, but feel that it is disingenuous to look at this choice in terms of its right/wrongness. If we take for granted that there is a certain moral humaneness that comes with being human (Paul does this when he says we all know it is wrong to kill) then we need to look at how this can become twisted to make individuals who kill, cheat, take advantage, and steal elections. This is where the focus should lie, why are these individuals taking a path that leads to possible killing? What is it in them that makes them prone to "evilness"?
Conveniently when we look at the statistics we find that some gigantic percentage of African Americans are making these choices compared to white people (African Americans in US ~12%, in armed forces ~20-30%). We can infer then, that black people are more prone to evil than white people. Of course we cannot infer this, and I don't even think Paul believes it. So if we assume that black people are not more inherently prone to killing, the next step becomes cataloging the differences between the two groups that might lead to their choices. We look at socioeconomics and find that black people are, on average, poorer than white people, they are more likely to not have adequate food and shelter, they are, again on average, less educated. These are the facts that are directly affecting the choices available to any particular group, and are what lie at the root of why many take up these "evil" jobs.
The worst part of focusing on the individual is that it actually acts as a buffer between the symptoms of the problem and its root causes. If we blame the individual for choosing poorly then we are in some way absolving the society of that same guilt. Society is responsible for the individuals that it creates to a very fine degree. I am not arguing that every crackpot out there is insane only because of their environment, but would point to the numbers of people in similarly affluent countries that don't share their plight. Why is the homicide rate in every other industrialized nation so far below ours? Why do we have 100s-1000s times as many people in prison? These are questions that may lead to appreciable changes in our culture and society, whereas qestioning the "evil" in any one individual leads only to segregation, separation, and excuses (if we add Paul's panacea of religion we get Crusades, Whoopie!)
