John Hurt's character is the same Time Lord that we generally know as 'The Doctor'. However, he is the only incarnation not to call himself 'The Doctor'. In "The Night of the Doctor", the Eighth Doctor realised that in order to end the Time War he would have to do things that the Doctor would never do. After regenerating, his next incarnation (played by John Hurt) stated that he was "The Doctor no more". During "The Day of the Doctor" stated that he didn't deserve to be called 'The Doctor'. The John Hurt incarnation then regenerated into an incarnation played by Christopher Eccleston, who called himself the Doctor again, and is thus our 9th Doctor. However, it should be noted that although the War incarnation did not call himself the Doctor, the events of "The Day of the Doctor" allowed him to keep his promise, making him worthy of being the Doctor again.
