The Hero is joined by allies. Sometimes, friendly animals in a story showing that wisdom comes from nature. This guiding figure is more than an actual character. This is a representation of an energy or spirit. Jungian psychology talks of this.
Corrupt characters seem to imagine there is more power in the way they are using it.
Pure selfishness, without any struggle with conscience, gives the illusion of greater power. Just because someone avoids struggling with conscience, or the concern for other people, or fairness, or ethics, does not mean these issues go away. The denied elements always return to present their demands. Only shared power is stable and safe. If we give ourselves over to only one side, only to power and control, the entire beauty of what a human being can become will not develop.
