after saving bella when she became 로스트 why does edward decide to drive her home?

Do 당신 mean when she became 로스트 in Port Angeles? He drives her 집 because he took her to 공식 만찬, 저녁 식사 after the 'attack' to make sure she was ok (and to spend some 더 많이 time with her)...when she got 로스트 in the woods..Sam brought her home. :)

So he wouldn't go back and kill the guys that followed Bella

so he dosent kill the guys and to make sur is o.k because he cares:)

Edward had, after he had been changed, a short time of, so called, 'puberty.' He didn't want to live on animalblood anymore. He wanted to hunt on human, like his nature is.
He only hunted on people who killed 또는 raped. He thought, if I kill a murderer, it makes me less monstrous. In the end, he stopepd and returned to Carlisle and, then, Esmé.
Because of this, it was hard for him to just turn around and go away. He makes himself do that bye thinking of Bella and the fake humans they pretend to be. He tries to stay with Bella so he has no time to turn around and hunt the rapers down. Also, he alsready loves Bella so he wants to be with her.

She had no other way 집 because her 프렌즈 where already back at forks
