Quote from tomorrow when the war began (movie)?

Ellie: Well I’m different to all of you. I have blood on my hands. I can’t tell if what I did was right or wrong. I’d like to think it was to save my friends, or as part of some noble crusade to save my country. Really, it just comes down to the fact that I valued my life over theirs, doesn’t it? How many people is it okay to kill in order to keep me alive? Mmh? At what point do we lose our souls, if we haven’t already? In the end I think we just have to trust our instincts. After all, it is all we have left, isn’t it?
