In one episode (the second to last episode in the fourth season - Journey's End), The Doctor (main character, very important) is accidentally cloned with only one difference between himself and the clone: the clone is half Time Lord, half human. Being half human, Clone Doctor does not have the same firm moral standing against genocide (only in this particular case, which is the Daleks trying to destroy 27 different worlds and become the only remaining species in the universe - so it's one genocide over 27). However, because Clone Doctor commits genocide by destroying the Daleks, he is forced to live in a parellel universe for the rest of his half-human life.
Even in a weird, british sci-fi television series, genocide is both present and still considered the "ultimate evil". It's interesting to me that a fictional series would present such a serious topic as genocide on such a level that all viewers are aware that it's happening, and that even though it is being used for the "greater good", it is still the worst thing imaginable. So why openly discuss something when it is only sad and makes the viewer sad? I think because it needs to be discussed and understood in order to prevent it (although I'm sure I will never in this lifetime see an alternative to genocide when it happens so frequently and so little attentino is paid to it).
