The difference between a hero and a villain is clear, both are men with ambition but who use the sword for different purposes. Although there is an overlap of black and white, self-righteousness, and morality, ultimately it is very clear to tell who the villain in your story is and who the heroes are, but what about friends and foes?
What is the difference between a friend and a foe?
At first you may think A friend is someone who is friendly to me, a foe is someone who is hostile to me. but let me ask you this, if the person who was to take your life, was calling you darling as they did it, would you consider that person a friend?
