I was thinking about having Chris/Betty kill Funtime Foxy. And I can loosely explain why. I'm kinda working on writing a few of my characters into different routes of the original game, just cause I was bored and couldn't think of much else. But I chose Chris to be my genocide run character. And his reasoning behind it is that he'll get home faster if he just kills everything that crosses his path, it gets them out of the way faster and keeps them out of the way. But with Funtime Foxy in Toriel's position, there's no way he/she would move without being either killed or spared over a long process. Chris would want to get her out of the way quickly, so he'd opt to kill her.
