In the 2005 reboot of Doctor Who, during season 1 episode 13 The Parting of the Ways, both the Ninth Doctor and humankind are saved from the Dalek fleet by the Bad Wolf entity, who turns out to be...
...Rose Tyler possessed by the Time Vortex.
This effectively made her a Goddess who could divide atoms themselves - although still not as powerful or dangerous as a Time Lord possessed by the Vortex would be.
On first seeing this entity, the Emperor of the Daleks exclaims fearfully:
This is the Abomination!
...before a Dalek unsuccessfully attempts to exterminate it.
However, "The Abomination" isn't listed anywhere as an alternate name for the Bad Wolf entity.
Why did the Emperor refer to the Bad Wolf entity as "the Abomination", and what does it mean?
