Thinking on it more than usual, I think I must be of the view that you are exactly what you are in that moment.
Having said that, I think that is because I dont believe in "good" and "evil" people like that. I think you are the sum of your actions, nothing more, nothing less. Does that make sense?
So people can do good or bad things, but they themselves are not different from those acts....

I think what I mean with the war comments is that the notions of 'good' and 'bad' is subjective
