Best way to kill Sims (if it is your cruel intent to do so):
Invite your fellow neighbors over for an otherwise middle-of-the road party. Make sure you've amassed a large reserve of cash, and build the grandest, most elaborate pool in the community. If you've managed to sweet talk your "friends" into actually coming over to your box social (because, let us not forget, those you aren't friendly with or barely know will avoid your house like the plague), then direct their attention to the pool area, where fun and adventure awaits.
Once you've schmoozed it up with your victims...er, guests, coax them into jumping into the drink for an orgy of good times and aqua-related (mis)adventures. Once they've all submerged themselves in your death chamber, you'll want to change into your best duds for the glorious moment of the apocalypse. Stand and watch your lemmings whoop it up as their social and fun meters climb, and then, right when they've had enough water polo and similar-related activities, steal the pool ladder right from under their trunks. You'll watch in devlish glee as your victims sprial into manic depression and anxiety, all while bellowing an opus of ungodly screams.
When the corpses start building up as the game goes on, you'll have to make room for the many gravestones about to inhabit your backyard cemetery. Watch the Grim Reaper make the life cycle come full circle, as your guests die with each passing minute. You'll find that there is a certain delight in purging the neighborhood of those infidels who didn't want to laugh at your jokes, or refused a consensual pleasure romp in the boudoir.
For those who survived the Four Horsemen of the Apocalypse, make sure you convince them to join you for your next get-together at your humble home. Little would they know that the day or reckoning is upon them, especially when it involves a BBQ and a backyard pool party.
