GOT:- John Snow is dead (or is he?)

So the George has decided to kill John Snow, probably the most interesting character in the show. Lets kill Tyrion next, follow by Daenery, then Arya. You know what, lets kill the dragon too. I know you are not going to kill Sam cause he sure does look like you :)

So is John Snow really dead? Maybe he is to be resurrected. Maybe he wargs into Ghost. Maybe he is indeed Azor Ahai or maybe he really is dead. Nobody knows which theory is real but everyone knows one thing for sure- John Snow knows nothing. :)
