From someone who has been in a severely abusive relationship with an alcoholic, and knowing how some people get ptsd and other serious long lasting problems from that sort of thing - I would say no way should that be in this sort of game. There is mischief, there are mean interactions, and deviance and so on, which should be enough for chaos I would think. You can create all kinds of intensely chaotic relationships as is. I really cannot fathom the need for something as serious and potentially deadly as abuse in the game. There are plenty of dark games with addiction, alcoholism, whatnot. But for a life sim that people use to escape - just, no, 100% no. I mean there are even a lot of people who can't play Disney Dreamlight Valley because of how manipulative and abusive Mother Gothel's whole persona / storyline is. I would bet that a lot of people would stop playing Sims if something that triggering were added.
