Will Elena end up dead in the seris and why not??

What do you mean by "dead"
If you mean vampire "dead" then it is a slight possibility but not any time soon
She cant die die because the whole series revolves around her unless she dies towards the end :p

I don't think she will become a vampire anytime soon. She is one of the stars of the show, it makes it more interesting if she stays human. She cares about two vampire brothers. If she becomes a vampire, I think it would spoil the show...everybody slowly becoming a vamp.....

No. She's not going to become a puppy-like angel or a vampire like she was in the books. The series is so much better than that.

I totally agree. The angel thing in the book was so stupid.
