In the woods at the twilight wedding, why did the werewolf Jacob suddenly become angry? What do you mean Bella will die?

He originally thought that this would be Bella's last night as a human being, and that Ed would turn her into a vampire after marriage, but Bella said she wouldn't do it for the time being, and joked that she didn't want to spend the honeymoon living with the vampire she had just turned into. In the pain of vampires, they wanted to have a normal honeymoon like normal people, so Jake was angry, because if they were like normal people, Ed's power would hurt Bella, a flesh-and-blood human being, and even hurt her during lovemaking. Killing her was beyond Ed's control. J was afraid that Bella would be hurt or even life-threatening. So he suddenly went crazy. In fact, I feel sorry for Jacob. Seeing the way Bella ran to him and hugged him, in fact, it was love, but. . J could only smile, a smile that made people feel heartbroken and shed tears.
