Do you ever kill a sim because they’re just okay?

If you don't serve a purpose in my game... you simply don't have the right to exist. I enslaved/killed off all premades either because their presence annoys me or sickens me, they've interfered with my plots.
Sims who interfere with the affairs of my game will be killed and replaced by the back up version on the Gallery, the Genesis version of the sim.

I have taken my sims' babies because they didn't come out how I intended, so I replaced them with the better versions of those sims.
