Alright, having become accustomed to the book, I'd suggest that Roger be removed. While the whole reason for him staying was because he was apparently already a monster before he came to the island...he only commits one murder by dropping a rock on Piggsy. As horrible as that was, he ultimately isn't heinous enough.
It also doesn't help that the other characters basically reverted to savages when they were on the island, and they each became awful in their own way. Well, except for Simon since he's Jesus.
Thoughts?
