If I had to pick one scariest thing bout becoming a father, I'd say... the whole thing! From the moment you find out, all the way through the pregnancy, the birth, a new level of fear and horror as a helpless, on-looking bloke and even then when they are out and running about in the world, the fear never ends. It's constant worry, and 'am I doing this right?' and 'why is he making that noise?' and 'has anyone ever died from eating ham?'. It's non-stop.
