Why Do You Want More Death in Your Game?

I don't necessarily want more ways for my sims to die (although death by disease should definitely become a thing, right now disease is just a useless, annoying moodlet that comes up every now and then for no apparent reason), but a higher chance of it happening, just for more drama and more interesting gameplay. I have an entire library full of books of life in case someone bites the dust unexpectedly, and I can think of at least two other ways to revive dead sims, but those will never be used if no one ever dies! And even if you don't have a book of life, a wishing well, or ambrosia, your sims can still "live" on as ghosts, so even if you don't like death, it really isn't such a big thing in this game.
