2. Give an example from your own life, the news, movies/t.v. or simply create a fictional example, which illustrates a person acting "in conformity with duty but not [acting] from duty." Hint: First you will need to give an example of a Killing is wrong. (Example) I didn't kill that guy who cut me off on the freeway because I would go to jail, not duty, then explain how the subject is acting in conformity with that duty but not because killing is wrong.
