For the most part, I see "evil", as expressed in people, as an absence of empathy. I see "goodness", as expressed in people, as being the humanity that is inherent in all people, and the divinity that is inherent in all beings. A lot of decisions that are made by people, that others would call "evil" or "bad", I see as being a result of disordered thinking caused a lot of the time by the "layers" that Amos mentioned.
