Eli: In all these years I've been carrying it and reading it every day, I got so caught up in keeping it safe that I forgot to live by what I learned from it.
Eli: People had more than they needed. We had no idea what was precious and what wasn't. We threw away things people kill each other for now.

Answer: Most likely, Redridge is giving Solara a chance to escape Carnegie's regime. At this point, he knows he's dying, but perhaps still wants the best for her. Remember, he had a crush on her the whole movie (blocking her while she was getting Eli's canteen filled, bargaining with Carnegie for her before chasing after them, even asking Eli nicely to give up the book after the gunfight in the house). I think it may also have been used as a self-redemption moment for one of the bad guys.
