"What if I fail them when they need me most? What if I can't be there in an emergency? What if someone takes advantage of them? Leads them astray? How can I make sure they know right from wrong? Do I know right from wrong? What if they need independence and I can't let them go?"
Any of those questions, if you dive deep, can be horrific and existentially dreadful to write about. Violence is easier and much less effort. But, it's kind of lame and about as realistic as a foam monster covered in red-dyed corn syrup jumping out of the shadows.
