Everyone is a monster, that is true. And I agree that anyone can _kill_ in the right circumstance (e.g. self defense, etc), but I strongly disagree that any disciplined moral character will easily become a murderer overnight.
However, the part you miss is the keyword discipline. To be discipline in morality means that you are aware you can be a monster and you actively choose not to be, even if it means what appears to be a negative outcome for you, relatively speaking.
Morality isn't free. It's not easy, and it requires diligent practice, aka it's a discipline.
By the time your in college, you should have enough discipline to not cheat. If you don't, you have a very untrained conscience.
