This is one of the absolute most incredible lines, but what makes it is Matt Smith’s delivery. There is calm rage there, anger beyond comprehension. The darkness hiding in the Doctor’s broken heart. It’s why, no matter how the series is being written, Matt Smith will always have my respect because he knows.
Sometimes I can’t tell if The Doctor is a Holmes or a Moriarty.
the reality of that last comment scares me
Both. The Doctor is both. He is a genius. An absolute genius. He fights for good. He saves the day, he makes sure things are all right, and he tries so hard. But he’s commited mass geniocide. Multiple times. He both saves and kills. Matt Smith utterly understands the Doctor.
