Shame
Sometimes seeing the best in a creature is impossible. Sometimes giving a creature a second chance is impossible. When those times come, I turn my head, run and never look back. Many worlds have been destroyed because I ran away, but I am not ashamed of my actions. There are times when a planet, or even just a person, needs to learn a lesson.
I saw what happened those five days. I saw the selfishness, the sacrifices made for that selfishness. I knew they always had that capacity. When faced with the end, they find a way to survive no matter the sacrifice. To deal with the sacrifice, they rationalize. They comfort themselves with words, making themselves out to be the victims, the heroes, the fooled. Never the villain though. They never want to admit to being the villain.
Seeing them make such selfish sacrifices and decisions, I have no choice but to run. The choices they make, the things they do, those actions don't deserve a second chance. Those actions are truly horrible, the actions and choices made by monsters.
I don't want to believe them monsters. I have seen so much greatness in them. Seeing their dark side, I'd be left with no choice but to destroy. Second chance or not, the greatness they have would not be overcome by the darkness.
There are times when this darkness is most prominent. Through the years, these times have gotten more and more common. My answer hasn't changed though. When I see those times coming, I turn my head away from the Earth with shame.
