10 Doctor Who Episodes Where Evil Won
9. Empire Of Death
In the opening scenes of Empire of Death, Sutekh destroys all life in the universe; past, present, and future. I think we can chalk that up to a pretty big win for the guy!
This was Sutekh's purpose, his mission – to destroy all life in the universe so he can reign supreme in his empire of dust, with nobody to challenge his supremacy. It's a striking moment, even if you know that ultimately, the Doctor and Ruby will save the day.
But still, full credit to Sutekh – he really put the work in here. He hitched his wagon to the TARDIS almost 50 years earlier from our perspective, but in terms of the Doctor's personal timeline, Sutekh had probably been raw-dogging TARDIS flights for centuries, possibly even millenia.
This enabled his army of Susan Triads to spread his gift of death to all of creation, and while the Doctor eventually reversed the death wave by, er, bringing death to death, Sutekh had a lot of time to bask in his victory.
