thanks to TV Tropes for reminding me how damn often RTD!Who does that thing of condeming the mass-killing of (usually) Daleks and getting (usually) the Doctor to decide not to do it and then getting someone else to kill them all anyway because we don't want the hero to make a horrible choice but we also don't want him and the rest of the universe to have to live with the consequences of his decision to nope out of it on moral grounds. so the story does in fact think that the Daleks need to be killed en masse but only if it can be done by a scapegoat or someone who is unaware of what they're doing and who thus cannot be blamed for their actions.
