Tad Garrison
I know his character was in the movie to help prove its point, but his fate really bothers me.
He was a good husband, a good father, generally a good guy the way he was portrayed in the movie. It just doesn't seem right that he ends up in hell. I see the reactions of his wife and daughter to his death and how the wife assures the daughter he's in a better place. I know she'd never know, at least while she's alive, but I'd hate to be the one to break it to the kid that her dad is not in a better place.
It just doesn't seem right to me that a God would do that to such a person.
