Why do Villain origin stories so often revolve around a girl?
If you watch many films & TV shows, you'll notice that there are many, many times when see a man becoming evil (I am talking about male Villains specifically here). However, how the man becomes the Villain almost always seems to revolve around a girl who he loved. Maybe it's through his true love being murdered, maybe it's a fear of his true love dying or maybe his true love betraying him. Whatever the case is, A heroes turn to evil often seems to be through a girl.
Below is a list of men who turned evil as a result of girl.
Anakin Skywalker - Star Wars
Slade Wilson - Arrow
Harvey Dent - The Dark Knight
Adam Monroe - Heroes
Cyrus (the Joker Rising)
Davis Bloom - Smallville (though technically it wasn't entirely to do with a girl, but in a way it was still centered around a girl that helped him to be evil)
So yeah... You get the picture! There are a lot of Villains who became evil through a girl in one way or another. Has anyone else noticed this?
Does anyone else thing it gets overused? And is starting to get a bit cliche?
