well, locking your sims in a room that is very tiny is always fun and having them starve to death. catching sims on fire is entertaining as well.
i also find that drowning sims is also rather fun. just experiment with things and you'll find the most fun way to kill off your sims.
No, Sims can not kill each other only the player (you) can kill Sims.
Yes, you have to download the mod.
Theres a lot of Sims on ps2 like: The Sims The Sims Bustin' Out The Sims 2 The Sims 2 Pets The Sims Castaway I'd say Bustin' Out is the best.
They get taken away
In the Nintendo ds version you cant kill your Sim.
no!
In the sims 3 it is impossible to kill a baby.

Sims 2 by far is the best. But Sims 3 looks very promising.
never my own, but sometimes i create a new sim just to kill them :D
Places like Mod the Sims or Liana Sims.
