An "evil" act does not make a person evil necessarily. We all do bad shit sometimes. My point was it's a grey area that can't be defined with 9 alignments outside of the structure of a game, but knowingly allowing your actions to cause harm to others is an evil act.

That being said, the idea of good and evil is entirely the result of fiction. I don't believe there's a black and white "good and evil" in reality. Human actions and motivations can't be defined so broadly IMO.
