Does feeling envy make someone an asshole in your eyes? Do you believe that people who feel envy can choose to not feel it? If they can't choose not to feel it, are they doomed to be an asshole (by your definition) for the rest of their lives, barring some change outside of their control?

To me, simply feeling envy (or any negative emotion) doesn't really say anything about the person. Actively stoking negative emotions or acting on them moves the needle in the direction of asshole, though.
