I think one of either Jackson, Ryan or Jason.
Jackson because he feels he'd be forgiven because he's got a son to keep and will still make it to the final.
Ryan because he's a selfish git and has no empathy for anybody.
Jason because he feels he's not as radiant as he wanted to be and might as well go out with some cash in his pocket. He can also take out his revenge on a woman by nominating one of them.
