The purpose of the war was to make human's realize that they needed to stop fighting. It was not our purpose to tell them exactly.
[He pauses. That is something takes him a moment] As an overall goal, yes it was worth. Death was certain for some whether we did anything or not. We could have sat by and let them fight each other. But isn't it better for several to die as opposed to all? Even my own death will serve in this purpose of ending the fighting.
For those who lost someone, no, I do not think the fact that there was a purpose will be of much comfort to them. There were more deaths than were needed.
