|It's the villain who gives the hero his hero status|
In trying to make sense of the conflicts in the world around us we come to see them as outward manifestations of this inner conflict. The individual on the left is trying to live according to their conscience, and thus will see the individual on the right as a representation of their own rebellious feelings of hostility to that conscience, a rebelliousness they are trying to tame. And the individual on the right identifies with the rebellious tendencies in themselves and identifies those on the left with the oppressiveness of their own conscience, which tells them that they should be more concerned about the welfare of the powerless, the planet, the animals, etc.
