|“||It is important to fight and fight again, and keep fighting, for only then can evil be kept at bay, though never quite eradicated.||„|
|~ Albus Dumbledore to Harry Potter, about the fight against evil|
The concept of Good vs. Evil is one of the most important parts of traditional hero-related media, indeed without this concept many would argue the idea of a hero could not exist - by its current definition a hero is a character who is "good" or "moral" while a villain is often the opposite: Even in media where heroes and villains are often blurred, it is rare for a character who is completely without morals to be considered a hero and even rarer that such a character becomes successful (though exceptions do exist).
The concept of Good vs. Evil is ancient and complex - much like the concept of heroes themselves (though in ancient times a "hero" was not so much moral as someone with superior gifts from the rest of humanity - what Nietzche would later class an Ubermensche - in time people attributed heroism with more positive ideals such as chivalry, compassion and strong ethics).
