Have you ever had that one sim you just wanted to kill off?

I married a Sim into one of my rotation families who was the daughter of Candy Behr and...someone. She was absolutely adorable. Turned out she hated children and was...lazy? Non-committal? Usually I work around bad traits but whatever her combo was started to drive me right up the wall, so I let her have a couple of kids and then fed her to a cowplant.
