"Life isn't black and white with "good/bad"." Really? You can't think of an act in history that society might agree was evil? And I'm not sure why everything has to have a "measure". Someone who approaches the world we live in (and their own life) in such absolute, reductionist terms is living, in my opinion, a very ufortunate life.
