Clint Eastwood famously starred in the classic spaghetti western, The Good, The Bad and The Ugly, and though it may seem like a perfectly useful way to categorise people, things are, unfortunately, not that simple.
Throughout my time growing up I was told that there was the good guys, and there was the bad guys. It was that simple. Black and white, with no overlap. In World War Two the Nazis were the bad guys, in Disney films it was obvious who was meant to be the figure of hate, in football Manchester United were the enemy.
As you grow up you learn to realise that this way of thinking about the world is not only far too simplistic, it is also inherently flawed.
