Sims is a great outlet for our devious sides, as well as our coddling mother hen sides!
My sims? My babies, the prettiest in any given town, the ones beloved of the Sim lord that is me the player. I coddle the heck out of them, they live such lovely lives!
But if a n y other sim in any way offends this precious group? Well, my wrath is mighty and I've got the evil from the dichotomy of man to express in a harmless way. A sim wife was a bad mother to my heir, so naturally I had her become an absolute villain and then took much pleasure in having all my precious sims shun her and have her life go terribly.
It's in the game design, man.
