I have a couple of times in the Sims3. When we got the casino world, I played an old man and realized the girl he was with was a gold digger that had the aspiration to see him dead. I called him off in the pool and he finally died. 1st and only time. I realized the baby she was carrying wasn't his, so I brought him back and kicked her out to baby daddy's house. 2nd time, I had a motorcycle man cheat on his wife. They had one child together. I usually don't do the cheating unless I saw a lady sim I thought was pretty and wanted her in my game.
