Mankind has, throughout it's history, fought. Whether it's one on one or nation against nation we have fought bloody, deadly battles for any number of reasons. Sometimes for no reason at all. Many believe that we can evolve out of our deadly nature. Are we just fooling ourselves that any mindset we may put on for a time can change millions of years of nature? What do you think? Me, I believe we are just as prone to killing as we have ever been. Perhaps we mask the reasons for it a little differently than we have in the past but we still kill none the less. Should there be an apocalyptic event that limited our ability to feed ourselves or our own herd (family) I firmly believe that those of us that would survive are those that would kill for the available resources, putting aside all thought of "evolving" into higher beings.
