It wasn't as if he didn't care for them. He did. That's why he did it, after all. He couldn't watch them suffer, so he did something about it. Dust Sans story with Nightmare's gang.

A fanfic/story of Nightmare and children bad guys! All of the bad guys are children excluding Nightmare and Error. This is a story of Nightmare being a parent. I am terrible at stories so this may be terrible. I own none of the art or characters.
