How to emotional kill a sim?

For my legacy, I'm trying to kill sims, it's a new thing for me. 

First, NPCs refuse to die. Okay, fair. 
But I tried with my own sims and only managed the embarrassed death. 

I had 2 different sims angry for hours and they never died. 
The first one was hard to keep angry as she kept having confident or inspired moodlet. But she was enraged for most of a sim day. 
But the second stay enraged for more than 4 sims hours, micro managed to feed the anger, and never died. Sure, she had started with the leftover teen anger moodlet that maybe protect, but even for the 3hours she was enraged without it, she never died. 

the first sim had also refused to die from hysteria, she was hysterical for several hours but Grim came and got her for old age. 

In the past I believe I had sims die from hysteria much quicker. 
It's not something I enjoy doing so I never experimented with it, but how many hours of emotional state should I expect before a death? 
Thank you for any help.

No mods no cc, but they were used early in game. On PC, I've most packs and expansions but for the latests.
