What kind of image can symbolize the following: pure evil and human's natural goodness inside him?

maybe a yin yang in the chest of a shadow with green leaves or something like hearts and stars or something happy on one side and fire on the other? I...think...I understood the question...

an image that is symbolic of pure evil: Hitler shouting at his horde.

an image that is symbolic of humans natural goodness: a baby.

Bruegel's Rebel Angels painting

added: what about just a portrait of a soldier and then the viewer is made to determine if it is an symbol of war or image of a hero??
