Don't worry, I fantasized about it when I was a kid. I wanted to create the ultimate, incurable virus that could wipe all human life off of the planet. Still wouldn't mind creating it, but I don't take that dream seriously. And I wouldn't release it upon discovery, anyway. I'd pass it down, along with all the research that formed it, to my first-born child, so that they may hold the key to ending humanity if they wish. Or if not, they continue to pass it along until the day arrives.
