This was an excellent beginning to something I feel has a lot of potential. First of all, I love you already because you stray from the usual, boring descriptions that so many (myself included) lay down, about what the people are like in the first paragraph. This defines a character by actions, and gives them depth by adding in the hint of regret the assassin (?) has for her past actions. Great stuff, keep it up!
Now I realize that there is no righteous path, it’s just people trying to do their best in a world where it is far too easy to do your worst. — Castiel
