Revised Research Question

Does the plagiarism of a work follow Johnathon Lethem`s proposal where it helps a plagiarized work, or harm the author who was plagiarized, and by extension is plagiarism a moral or immoral act? Do all authors plagiarize work from others, and if so does that mean that all authors who have plagiarized should be punished for their 'cheating', or should authors applaud others when they borrow ideas and build upon them to extend the original idea or make a new one?
