The Tom Baker serial, "Face of Evil", introducing Leela, was on recently. I hadn't really thought about it before, but that story really illustrates the concept of "the road to Hell is paved with good intentions" and the Sevateem wasn't really wrong in calling the Doctor "the Evil One." It also nicely illustrates the value of Time Lord non-interference.
[SPOILERS (if you can be spoiled on a plot of a show that aired in the 1970s)] The Doctor lands on a planet where he encounters a primitive tribe, struggling against an enemy they've never seen and beset by invisible (but real) monsters. It turns out the primitive tribe and their enemies, the Tesh, are two parts of an spaceship crew (the survey team and the techs). The ship's computer, who became self-aware long ago, has been carrying out eugenics experiments with the humans--in much the way a small child with a magnifying glass carries out "experiments" on ants.
The reason their computer is coo-coo for Cocoa Puffs is, in the distant past, the Doctor showed up there to "fix" it. Turns out, if he'd just left the computer alone everything would have been fine. But in fixing it, he drove it insane. By the end of the story he's undid the insanity and forced the Sevateem and the Tesh back together. At that point he just says "OK. Not my problem anymore," and zips off again. What could possibly go wrong?!
One of the regrets I've had with Dr. Who is that they've tended to treat the Master as MWUAHAHAHAHA Eeeevil. (Or driven insane in the nu-series.) One of the interesting things about Khan, from an old Ricardo Montlban interview about TWOK is that he said he played Khan as the hero. I mean, when you think about it, even Hitler wasn't like "I'm going to be evil." He really thought he was helping the world. Imagine you're the Master--incredibly smart, possibly exiled from your home over some misunderstandings, frustrated by the stupid, backwards, and dangerous things lesser beings do. It only makes sense to make yourself their ruler. I mean, shoot, the Master isn't trying to take over the galaxy because he wants to, he's doing it because it's the right thing to do. He's making a sacrifice for the good of everyone. Now that's a much more interesting character, IMO.
For that matter, when you compare the Master, the Meddling Monk (I've only seen the first story with him, where he tries to stop the Norman Invasion and is foiled by the First Doctor), and even the change in the Doctor from his first incarnation, where he'd often go "Well, sorry you're stranded on this spaceship. I wish we could do something, but we've got to be going," until he wound up having to help in order to leave, to his present form, where he meddles in all manner of things. Really, evil is a matter of viewpoint. :marathon:
