Im in between Death Eater and Pureblood because I if you at least try to read the books and they just aren't working for that's fine. Or if you fully intend on reading the books but you are really busy or have other books that you have been wanting to before you wanted to read Harry Potter I'm fine with that, too. However I will dislike you if you completely blow off the books.
Dumbledore knew the truth. That to kill the horcrux alive in Harry, that Harry must himself die and willingly. Dumbledore knew that death would only be temporary. Why do you think he was waiting for Harry on the other side? He couldn't tell Snape that or he might have faltered in his purpose. Dumbledore knew Harry would live.
