Wow. I love that Cooper quote! I'm going to have to write that down. However, it's more of a gray situation than a good guys / bad guys scenario. When faced with starvation even good people will do whatever it takes, and this will sometimes put them against other good people. I don't think it's a matter of race (although history shows that people will use chaos and anarchy to settle old scores.) In the above scenarios it's violence, anger, hopelessness, badness and survival that will try the hearts of good men and women. Those that are able to maintain the moral high ground and live life even remotely similar to pre-downfall will be the vast minority. Get away from the masses and prepare as well as you can. That's your best chance at being among them.
