I don't think any celebrities need to die. There are plenty of truly evil people out there who could do with seeing the light at the end of the tunnel without resorting to killing off a bunch of rich people.
Here's my list:
Robert Mugabe
Idi Amin
Slobodan Mlosevic
I know they don't appear in crappy TV programs, but they killed alot of people which must mean they are nearly as bad as .
