And in keeping with the World War Two theme...if people (the allies) didn't take lives maybe Germany might have taken the whole of Europe and the UK and then what? I wonder what that alternate reality wold have looked like.
An alternative reality... perhaps it is hard for us to stop and do what really corresponds to us as citizens, as perhaps those Christians or non-believers of God that we say we are on a daily basis. But we continue to bet that when we have passion for what we do, principles, and ethics, even with the mistakes as human beings that we are, we manage to do our work with that objectivity of which you speak.
