I just delete the ones that tick me off, or allow them to die of old age. I've had so little time to immerse myself in the game, I really haven't had the time to actually plot then carry out a death scenario. But an elderly Sim recently showed up in my Sulani save, I can't remember his name, who is mean, and loves to fish wherever my Sims are fishing even when I take my Sims to different worlds. He yells at my Sims, stomps his feet, angry walks everywhere he goes and constantly tries to pick a fight with every Sim around him. He is the only Sim that appears to carry a true grudge, and no amount of chatting changes his mood. Maybe he will become my first victim of a death plot. Because he has made it quite clear he hates everyone. And that goes for hating the pets in my game, too. I don't understand his behavior, he disrupts the game and I can't be sympathetic toward Sim that goes out of his way to be mean to dogs and cats. And all of you have given me some very good ideas on how to kill him off. Thank you!! :D
