If humans could add years to life by eating babies, would it be wiser for me to eat other peoples children and let mine live or to fight for a world where we only eat our own children? In the first case, it would be theoretically possible to erect a worldwide SNOWBALL138 genetic empire, but in the second case, I would only be one of billions of immortal humans.

It's just a book. It's not worth hurting each other over.
