"Sometimes fighting is unavoidable Erica. Killing, unfortunately, is often unavoidable as well. If you are forced to do it often, then for the sake of your own survival, you will find it less abhorrent." She sat up and looked directly at Erica, her great almond shaped eyes solemn and focused.
"That is something that you will not be able to stop. But what you can do, is make sure that you never become indifferent.

If done for the right reasons, it can make you a hero."
