What is the best Sims game for doing demented stuff?

Pets I guess. They say the first sign of psychopathic disorders is showing cruelty towards animals.

Any of them, really.

Even the first game let you torture your Sims if you were so inclined.

I once made one of my Sims workout for 6 hours (game hours). When he finished, he stood up and immediately collapsed.

Another time I didn't quite make the bedroom wide enough so even though there was a little space on either side of the bed, apparently it wasn't enough for the him to get into bed. As a result he would run in circles at the foot of the bed and whine, until he collapsed on the floor in a puddle of his own pee.

The next night, I let him do the cooking. He set himself, the stove, and the fire extinguisher on fire. His roommate ran around in a panic looking for a phone (I forgot to put one in) and eventually the whole house burned down, and set fire to the rest of the neighborhood, literally destroying all my save games. I had to reinstall to get a new set of houses.
