Bring up the whole morality of altitude issue where the Doctor who won't use a gun because killing is immoral, has repeatedly destroyed whole worlds. The Doctor has no problem sending others with guns to do the killing (Brigadier Lethbridge-Stewart), but refuses to get his hands dirty.

As an example of this, the Fires of Pompeii episode has him deciding that incinerating thousands of men, women, and children was acceptable collateral damage in order to get the Pyroviles. And blowing up Vesuvius is necessary because the Doctor is too pure to use weapons. He does this a lot: guns are very bad, so lets blow them up instead. He thinks like a Leftist (or at least his script-writers do).

He does this a lot: guns are very bad, so lets blow them up instead.

Being a time traveler the perfect foil for him would be one of the Old Contemptables. A regular Tommy Atkins of Queen Victoria's army complete with SMLE or Martini-Henry, bayonet and the guts to use it. A Brit from before the age of political correctness who would have no problem calling out the doctor on his hypocrisy. Someone who wouldn't hesitate to apply Rule 303 to Davros, the Master or any other threat to his friends, family or native land.
