In the Sims 3 I wanted to see how big the family tree could get so I knocked up half the town. There were a lot of angry couples stuck living with each other and most people were related in one or the other preventing any new romances
Aside from trapping them in the pool, trapping them in the house, setting them on fire, making them live in a tiny box with no bathroom...?
Not much.
Trying to kill children definitely qualifies, though it's a boring answer.
But also: Married sims and kept them in the basement with an easel. Locked other sims in my lot, didn't let them escape.
This gives me some GrayStillPlays vibes back when his GTA 5 parcours were still an occasional thing.
