And one day we are done.

There was this survey. Not scientific, just man on the street kind of thing. After asking people about defense spending, and questions of ethics. The program came to the conclusion that we are understanding empathetic healing war-machines capable of mindless slaughter. They went on laughing at the contradiction, but it is not a contradiction that runs very deep. The two things are tied together, feeding into each other. Your compassion for one group is what will drive you to slaughter another. And it isn't by mistake. It is an emergent property of success. Because people who do this will be more successful, by protecting their kin, and removing all the other competition from the DNA pool. It only takes a few generations for people who feel at peace with this imbalance to start dominating an area. 

Our emotions are there to drive us to act. To convince ourselves of what needs to be done. It felt right. I did what I had to do. There was no avoiding it. 

Everything that happens often in many people is not there by mistake. Everything has its place, and in its place, a season.
