buy, use fully, and return → unethical
Evicence in Application
James bought an item and later returned it.
Conclusion in Application
The return was unethical.
Evaluate
Whenever we see this style of question with a Principle and Application, the application will conclude the right side of the Principle, but it will fail to fully establish the left side.
Were told that James bought a camera and then returned it after getting all the use from it he ever intended to get?
No. We know he bought it and returned it, but we're still missing that bold part.
Goal
Look for an answer indicating that James got all of the use from the camera that he intended.
