"I won't cheat." 

Dale Murphy  

If you cheat your way into winning something, you actually didn't win fair. It's better not to cheat because if you cheat and you knew it was wrong you're going to have guilt and that guilt can stick with you forever. For example if you are having an exam on one of your classes and it's really important, you end up cheating and you get a good grade, you'll start to have guilt because you knew it was wrong and you still did it. So you might as well not cheat at all because if you cheat you will have problems to deal with later and you don't want that.
