Here's a simple question: Do you think anyone can be pure evil?
Pure evil, I'm not sure. If someone were that way it would land them nothing but trouble while being left alone or incarcerated or executed.
Evil is the opposition of will onto others. If the action knowingly causes any kind of grief, then the action is evil.
It needn't be addressed as evil, so regardless of what one believes, even for those who think evil doesn't exist, even they can label what real actions would be evil if such a concept exists.
Life is the temporary state of being. Misconduct is the offspring of misery and poor choice. The greater awareness knows what we do is in proportion with what we deliver, and that poor behaviors is an inadequate way to progress in both temporary, and eternal states of being.
Edit: In order to do more wrong, one would have to maintain periods of decency. Perhaps all that is required is an agenda.
When asked "what does Evil mean" I simply replied the dictionary has the answer to that.
Though I needn't mention it, the words synonymous with the word Evil, are all real too.
