how should I kill my sim?

So for the sake of story one of my sims has to die, but I want the death to fit to the story therefore it can not be goofy like death by cowplant or too sudden like eating bad pufferfish.
I like the poison from JA as it takes several days and could be played out as having a terminal illness, as I want it to be dramatic, but the getting poisoned part is hard, I do have another sim who technically could curse him with "marked for death" but it wouldn't fit the story as she has no reason to and I do not see him as a jungle explorer either...(is there a cheat to poison him?)

what would you do for a somewhat realistic and dramatic but not too sudden death?
freezing, overheating, burning and electrocution all are too sudden for me and anticlimactic, so there is not much left...
