Damon can not die.

Definitely, if Damon dies, I will no longer follow the series. Will end all grace. Stefen can die without insults. But, what is? Damon die? is horrible! If That happens, it will happen the same thing That happened with the books, remember? You Remember When Damon died on the book series and all fans of Damon stopped buying books? Which was a tremendous fall, because almost all fans of the series love Damon. Only a few creatures who like Stefen more, but what is? If you want to spoil the series, just kill Damon.
