And just a few pages after that, when it seems like the Doctor's psyche is going to fracture, the Dalek conditioning tries to give him a "The Reason You Suck" Speech, and the Doctor responds with a great Shut Up, Hannibal!:
Dalek: You require control, Doctor. It has always been said... how often have you been accused of causing more damage than you repaired, Doctor? How often were they right?
The Doctor: Oh, but how many lives have I saved? How many civilisations are free from slavery? Tyranny? I do far more deliberate good than accidental evil. And you only offer disciplined, logical destruction. No, Dalek. I do not accept!
- After so many TV episodes with the Doctor going on about all the "harm" he does to those around, him, it's very refreshing.
