Okay, unlike bugged Old Lace, Vengeful Deity works.
Just got it. Wasn't hard, and it was fast and easy.
Just go into manage household, add 5 random elders, use dice for name, click any traits. Romance one by one, then doublewoohoo them in the rocket.
Repeat the process once more because you need to kill 10 of them.
Yolanda came last, I felt a bit sorry for her, but well...

And found (yet another) bug.
When you go twice on woohoo while being sad because of previous loss, the first woohoo message appears as it should, but it also appears when you go for the wohoo the second time with the same sim.
It works just once if you're not sad.
Here's one such pic:

This bug is so irrelevant I won't even bother to report it on RA answers HQ, they should work on critical bugs not things like this one, right?
.
Now... Which achievement to try next...
