Princess Mononoke has a variety of complex characters. San, for example, has intense emotions that are never hidden away from other people. She does not even try to hide her intense hatred for humans. I think that is because she was raised in the forest among the wolves. When she grew up, she was probably taught not to hide away her emotions because cutting off a part of herself would endanger her life. There is a good and evil going on inside of San. There is good and evil going on inside all of us, but San is more in tune with every aspect of
herself, and she is able to freely act upon what she feels without second-guessing herself. San grew up in the forest, it is and will always be her home and the only place she feels comfortable. She loves the forest and every animal and plant in it. She respects the life and death of every creature, except the humans. The good in her is heavily over-showered by the blinding hatred she feels for the humans. Her hate is not something that could ever fully disappear. Her hatred runs deep in her veins and she is not afraid to show it to
those she does not like. The evil inside her can not be scrubbed away by Ashitaka's
love and kindness. Perhaps, in time, she would be able to trust the humans.
Lady Eboshi is a completely different story. She is a woman of the city, of modern advances, and of tough opposition. Lady Eboshi cannot afford to be seen as weak in front of her enemies. She hides away her emotions and embraces her life with
statue-like grace. One cannot tell whether or not she is feeling vindictive, elated, or concerned. She keeps up a tough front so her enemies would think twice about messing with her. She took the
women out of prostitution and put them to good, honest work, she had the men do hard labor, and she gave the lepers care and jobs. All that good is also over-shadowed by her hatred for
San, the wolf tribe, and any part of nature that gets in the way of her city's improvement. Ashitaka told her a few time that she has a demon inside her. I believe that demon was greed and hatred. He had to keep telling her about her demon because she could not recognize it inside her. She is not in-tune with every aspect of herself, so she would have never been able to see how the evil inside her was taking over the good.
