Which Doctor had the best interactions with Davros, and why? The 4th, 5th, 6th, 7th, 10th and metacrisis 10th Doctors all interacted with him and/or threatened him, yet only the 7th Doctor and the metacrisis 10th Doctor went through with their attempts to eliminate him/the Daleks - why is this? Did the Time War have any impact on their interactions? Given the 7th Doctor's booby-trapping of the Hand of Omega, the 6th Doctor's tacit approval of blowing up the ship containing Davros's new Dalek army, and the 10th Doctor's own actions sending the Daleks into the Void, what do you make of the 10th Doctor's anger at the metacrisis Doctor for "committing genocide" against the Daleks and Davros?
