Though you may try to go in a certain direction fate pushes you into the opposite direction. In the quote it says, “We had thought to slay another, we shall slay ourselves” Even though you meant to hurt another person you will only end up hurting yourself. It is you not them who will have to live the guilt of slaying someone which in some ways worst than being slayed. You have to deal with the pain, they will not. Also it’s hard for a totally new hero to really pave the way for rest of the world’s heroes since as a society we have really decided what makes a hero. That is the expectation and that is the reality. So if a new hero does come along and is truly a new breed of hero then society will most likely brand him/her a villain and that hero exploring a new labyrinth will never be a true hero in the eyes of society.
