No, some people will always cheat. Not everyone chooses to cheat. Moreover, cheating is a moral choice made by the individual who has cheated.
Not only is it a morally dubious choice, it means your grades and credentials are based on a lie. That paper, essay, assignment, exam, grade, qualification or degree are base on a foundation that is a lie. By cheating you are passing someone else's work off as your own, - claiming a grade you have bio right to, and passing yourself off as knowing or having mastered material or done work which you clearly haven't. Actually, I confess myself surprised at the lack of concern expressed by some on the thread about the consequences - not merely academic - of such an action.
If ambition and self-preservation are considered sufficient justification for cheating, what is to say such moral ambiguity will not follow this individual into the work place? Professionally, how can the work of such a person be trusted if the very foundation it is built on - a degree, or a grade achieved by cheating - has come about through cheating which is a form of lie?
