This one would be fairly major if it were to happen, with Who knows what repercussions on the universe and the past/present/future of the Daleks and The Doctor. Speculation started in the Daily Mirror earlier this year, and it has picked up pace since, that Caladi's Time Lord would actually murder a young Davros, seemingly based around this quote from Tom Baker's Doctor: "If someone who knew the future pointed out a child to you and told you that child would grow up totally evil, to be a ruthless dictator who would destroy millions of lives, could you then kill that child?" It's believed that means The Doctor is going to have to make a choice, and that he will actually choose to kill the creator of his oldest enemy. The Daleks were in the series 9 trailer, as was a planet that looked a lot like their home, Skaro. Then there was a picture (above) released from the series premiere, that Capaldi at Comic-Con described as hinting "at a battle, it hints at the Doctor being in a very traditional battlefield, in which he tries to help a victim of war€ but it backfires." The murder of Davros would certainly fit the bill with that, but what would the cost be on the show? It would not only make The Doctor a ruthless murderer (something the show hasn't shied away from in the past), but more pertinently would surely wipe the Daleks from history, given Davros wouldn't exist to create them.
