[Bella:] If your life was all you could give to your beloved, how could you not give it? (Preface.5)
Bella believes that if you truly love someone, there's nothing you wouldn't give him or her, even your life. Is that a valid definition of true love?
[Renée to Bella:] "Once you make up your mind, there is no reasoning with you." (1.154)
Renée suggests that once Bella makes a choice, no one can sway her decision. Is that a positive or negative quality?
[Edward to Bella:] "Look at my mother. Look at my sister. It's not as easy a sacrifice as you imagine." [Bella:] "…If it's a problem later, we can do what Esme did – we'll adopt." (2.55)
Edward believes that Bella doesn't understand how much she's sacrificing in not being a "real" mother, while Bella claims she makes no difference between biological children and adopted children. Do you think she's telling Edward what she truly believes?
[Bella:] "…a pile of human bodies, drained and lifeless." (2.128)
Bella recognizes the faces of her school friends and parents, and fears that's what she's going to do, what she will become.
[Bella:] "I knew the sacrifice it has taken him. And then I'd ruined it, turned his gift into a disaster." (4.222)
Bella knows that Jacob is making a sacrifice in attending her wedding, because witnessing her happiness with Edward, another man, causes him great pain.
[Seth to Leah and Jacob:] "They're people to me, and I'm going to protect them, 'cause that's what we're supposed to do." (12.63)
Seth has developed an affectionate relationship with Edward and the Cullens. For him, they're no longer vampires, they're people, and he considers it his mission to protect them from harm.
[Jacob to Bella:] "[Rosalie] understands that you're gonna die and she doesn't care, s'long as she gets her mutant spawn out of the deal." (13.40)
Jacob believes that the baby's life is more important to Rosalie than Bella's life is. Do you think he has a point?
[Carlisle to Jacob:] "I didn't mean that you would be… incapable. But that it would be very wrong. " (14.162)
Carlisle knows that Jacob would fight his own pack to protect Bella and believes that it's wrong for Jacob to make that sacrifice. Is Carlisle right? Is Jacob making the wrong choice?
[Jacob:] Even after I'd eaten my share – not because it smelled irresistible away from the vampire burn, but to set a good example of self-sacrificing tolerance for Leah, she'd refused." (15.12)
Jacob believes that by acting as a role model for Leah, he'll make her follow his lead. In vain. Does his failure make him a weak leader or is he really using "teaching Leah" as an excuse for eating Esme's food?
[Bella to Edward:] "[Alice] was willing to die herself rather than put [Jasper] in danger. Willing for me to die, too. Willing for you to die." (29.104)
Bella seems to accuse Alice of sacrificing anyone's life, including hers, for Jasper. If the roles were reversed between Bella and Alice, do you think Bella would fight for Alice or try to save Edward instead?
