I couldn't tell if it was the adrenaline, or just sheer willpower, but it was like a switch went off in my head. I was instantly calm and rational, when I probably should have been freaking out like my wife had. A type of coldness went over me, once I took a moment to consider it, I realized that my mind had gone to a very calm, quiet place. The awareness stretched out in that smallest infinitesimal fraction of time, where all moral qualms were gone. I exist, and because I exist, anything opposed to me existing must die. I knew that thinking like this wasn't normal, but I also knew that I could worry about this later.
