question about apoptosis and necrosis

I have hope this is the right place to post this. please forgive me if it is not.

I have done alot of research on my own and have discovered much of what i am looking for, but i am unable to find one thing.

Lets say that apoptosis or necrosis or both attacked an entire organism, not just a spesific part but the entire thing, like somthing casued all the cells to do this, would the organism just dissappear.
The reason i ask is im a writer, and i have a new idea for a story, and im doing the research for it right now.

Any information would be helpful.
