Your idea about deducting the points of terminals who don't end up dying from the contestant's point total is one I thought of this past year when reading the 2009 pool. Let's do it!
I'm picking ten people who look like they need to die soon:
In a League of Her Own Lindsay Lohan Pamela Anderson
All Hail the Chief Old George Bush Jimmy Carter
To Boldy Go William Shatner Leonard Nimoy
Oh, Rob! Dick Van Dyke Mary Tyler Moore
Does it Matter Which One? an Olsen twin a Pointer sister
