But what about The Kaleds?

An important thing to remember with these kinds of stories is that the characters aren't privy to everything that we as the audience see. It's a common mistake people make like assuming that everyone knows what happened between Luke, Vader and the Emperor on the second Death Star. Characters only know what they have observed.

The Doctor does go back to try and destroy the Daleks, but production has progressed by such a point that when the incubator room is destroyed, it will do little more than delay them. By the end of the last episode, it's less about moralising and more about getting out alive. Locked in Davros's office, they observe the confrontation between the Dalek creator and Gharman that is perpetuated solely for the purpose of identifying who of the survivors is loyal to the development of the Daleks and those who need to be destroyed. Ironically, if Nyder hadn't snuck out at the crucial moment, the Doctor, Sarah and Harry would have been massacred with the rest of the dissenters. If not while Gharman was alive then later when the Daleks turned on their creator and wiped out the rest of the elite.

This is a story where if you are shot, you die. Nothing on Skaro will stop that and staying around to try and help the unseen majority of Kaleds limits their own chances of survival. The Thals were going to seal the bunker one way or the other and production had extended to the point where virtually every corridor was patrolled by a drone. They catastrophically outnumber them and they are willing to kill. As a civilian, you only really have one choice and that's run. Run before you're killed like everyone else is going to be. It's certainly not altruistic, but it is necessary. The Doctor cannot do a greater good since if he dies there trying to help everyone. As he points out, he cannot save everyone. That's just not possible.
