No, think about it as an RPG... you build up your "perfect" family and try to get them through life... In The Sims 2, the children grow up and any "traumatic" experiences they go through will be remembered and they would grow up with "emotional scars". They now have memory, in old Sims the guy can be having a threesome in the next room and the wife would never know, but now, lets say that the wife is at work, but the daughter sees them, the daughter will tell the wife later on in the day... So there's no other option but to kill them both.
