Why doesn't Edward want Bella to become a vampire at the end of the Twilight movie? Traditionally, becoming a vampire would be pretty gruesome. However, Stephenie Meyers vampires are far from traditional. In the Twilight world being a vampire would have it's advantages.

First, Twilight vampires are not harmed by the sun. This means they are able to walk around during daylight. It's how the Cullens attend high school. The do live in the rainy Pacific Northwest because they glow in direct sunlight. The glowing would be difficult to explain, so they only go out on overcast days. You could still be in the sunlight as long as humans do not observe you. Since the Cullens play a private baseball game, you can imagine a private sunlight excursion.

Second, the ability to withstand daylight means Twilight vampires are not asleep during the day. In fact, sleep is not necessary at all. There is no coffin or dirt from the original grave that Edward must rest in.

Third, the Twilight vampires can survive on the blood of animals. This important fact means the Cullens do not murder people. Edward describes himself as a vegetarian. Edward does struggle with his desire to kill Bella and drink her blood. However, he doesn't have that problem with anyone else. Meaning the likelihood of him loosing control around other humans is remote.

Fourth, the Twilight vampires are immortal. Edward does not age, but remains a youthful man, fit and in his prime. Edwards diet is also unlikely to make heavyset, so he will remain youthful.

Finally, the Twilight vampires have strength, speed and various other super human abilities. Rosalie has an ESP like clairvoyance, and other Cullens are said to have gifts.

In the end becoming a Twilight vampire seems to have more benefits than drawbacks. The only two drawbacks being that you must live drinking the blood of animals and that you must socially avoid direct sunlight. In return you get immortality, you no longer need to sleep, you gain super strength and speed, and you may have some gift like Rosalie.

Isabella "Bella" Swan moves from sunny Phoenix, Arizona, to rainy Forks, Washington, to live with her father, Charlie. She chooses to do this so that her mother, Ren�e, can travel with her new husband, Phil Dwyer, who is a minor league baseball player. Bella attracts much attention at her new school and is quickly befriended by several students. Much to her dismay, several boys in the school compete for shy Bella's attention.

When Bella sits next to Edward Cullen in class on her first day of school, Edward seems utterly repulsed by her. However, over the next few days Edward warms up to her, and their newfound relationship reaches a climax when Bella is almost run over by a fellow classmate's van in the school parking lot. Seemingly defying the laws of reality, Edward saves her life by stopping the van with his bare hands.

Bella then becomes hellbent on figuring out how Edward saved her life, and pesters him with questions constantly. After tricking a family friend, Jacob Black, into telling her local tribal legends, Bella concludes that Edward and his family are vampires who drink the blood of animals instead of humans. Edward reveals that he initially avoided Bella because the scent of her blood was so desirable to him. Over time, Edward and Bella fall in love.

Their relationship is thrown into chaos when another vampire coven sweeps into Forks and James, a tracker vampire, decides that he wants to hunt Bella for sport. The Cullens plan to distract the tracker by splitting up Bella and Edward, and Bella is sent to hide in a hotel in Phoenix. Bella then gets a phone call from James in which he says that he has her mother, and that Bella must give herself up to save her. She does so and James attacks her, but Edward, along with the rest of the Cullen family, rescues Bella before James can kill her. Once they realize that James has bitten Bella's hand, Edward sucks the venom out of her system before it can spread and change her into a vampire. Upon returning to Forks, Bella and Edward attend their prom and Bella expresses her desire to become a vampire, which Edward refuses to let happen.
