How can you kill your sims?

Answer 1

well actually there are many ways. you can starve them, they can die from a fire, but a very interesting way is to place your sim in a swimming pool then build a wall around the pool. for more ways you can go on YouTube.com and type in ways to kill your sim (etc.)

Answer 2

*for all these steps, make sure free will is off.

1) starving them to death 2) starting a fire, then click the fire and make them try to put it out themselves, as long as they don't have a smoke alarm, they will eventually die. But make sure they don't have a smoke alarm or this won't work.
3) put them in a pool, and remove all the ladders.
4) turn off free will and don't do anything.
