There has been very few instances where I ever actively killed a Sim. Most of the time it just happens. If a Sim deceases before their 'Time', then I will very often roll back a save, or flat out restart that family again. In my ancestral save, my 7th great-grandfather died in 1770, three years before his daughter, my 6th great-grandmother left the great Colony of Virginia with her husband and seven children, one a babe in arms. So, since I use MCCC, I simply targeted him. Hey, it happened.
As for any other time, I do have to say I was so fed up with the lack of random deaths in Sims3, that I was willing to allow one of my Sims to be careless when he fixed the broken dishwasher. He didn't mop up the floor beforehand. Had no effect whatsoever. But, much later on in the same game save, his Rock Star younger brother did electrocute himself to death. He had a broken spa and of course there was water on the lawn. Who mops a lawn, right? And besides, his older brother was standing in a puddle in the kitchen and he didn't get hurt … I had panned the camera up to the third floor of his residence, since his wife was about to do a radio broadcast. That's when I hear the ominous music. There Erik was crumpled on his side by the spa. Dead as a door nail. :open_mouth:
But, no, I don't normally 'take out' my Sims. LOL Interesting thread, though.
