I'm trying to understand what all of you guys' points are as I'm not good at understanding English.
I'll try to explain more specifically:
You love your Sims, and consider them an extended family of sorts, so you treat them as well as you possibly can. There's nothing wrong with that. It's how you like to play and you get enjoyment out of that. I am very much the same way: I get attached to my Sims, and I don't go out of my way to treat them poorly. But I don't like to spoil them, either. Part of the fun I get out of the game is watching and helping them overcome the hardships of their lives. If something bad happens to them, they have to work through it. I don't remove moodlets, set their needs to static or use money cheats. Anything my Sims have, they earned. Of course, if I'm trying to do something in particular (like the scenario I mentioned or create a ghost family), I have no qualms with killing Sims. However, I do not do this just to do it. There has to be a
specific purpose behind it.
I am a bit of an oxymoron: I am a devout pacifist who has never even struck another person in anger in my 43 year life span. Despite this, I have a deep appreciation for
fictional violence (real violence is still abhorrent to me). But if I have that need to be exposed to violence, there are better and dramatically easier ways for me to fulfill that need than to kill Sims. I have numerous violent video games and an entire library of violent movies to choose from.
There are other people who play the game much differently than we do. They find it amusing to kill Sims, for whatever reason. This is how
they get enjoyment out of the games, and there is nothing wrong with it either. There is a certain amount of creativity involved in setting up a situation that will kill a Sim, and it doesn't always work. And to be perfectly honest, I would much rather see someone committing wholesale slaughter of virtual people in a video game than to see that person harm a single flesh and blood human being. So if this is somehow therapeutic to them, fantastic.
