Doctor Who: 10 Times The Doctor Being There Made It Worse

5. Dalek

There’s a lot of similarities between the first Dalek story of the classic series, and the first of the new series. The Doctor’s curiosity and/or need to help out leads him to follow a distress signal to the location of Skaro’s finest, and by being there he causes it to go on a massive killing spree as revenge for being imprisoned.

Before he turned up, that Dalek had no intention of breaking free and was doomed to be tortured into talking, after which it would just become another piece in the museum of Henry Van Statten collecting dust. But once it saw its arch-rival, every bit of the hate and determination to exterminate came bubbling right back up to the surface, and now it had the perfect excuse to break free. It was just sheer luck that it didn’t anticipate that by feeding off Rose’s DNA that it would become more human and start questioning itself to the point of suicide.

At the end of the story, we have Van Statten’s new assistant declare to her boss that the events have led to “200 personnel dead, and all because of [him]”. Not say, because of the Doctor following that signal.
