You can use words, but when does it end, and what makes you think you are going to end up better off?

Violence ends when non-violent reforms are able to succeed. The real value of violence is that it makes the non-violent option palatable to the political center.

The doctor was against violence as a principle but he famously uses tons of violence (I guess in the form of trickery) but as a last resort.

House: “fear me, I’ve killed hundreds of time lords”

The Doctor: “fear me, I’ve killed all of them”

The problem here is that the war already started but just one side is really fighting it.

I would be in favour of not starting it too, but it’s too late now.
