Difference between victimless crimes and one that affects allot of people.
You agree with the underage gambling law, but wouldnt you agree that cheating on a test which is breaking a rule/law, obviously one shouldnt cheat. You didnt give a reason to why you were against underage gambling except saying it left a bad taste in your mouth. And here you are saying cheating never felt right. I am assuming you think cheating is okay, correct me if Im wrong, because why would you cheat if you dont think it is okay.
At least in underage gambling you know the risks you take, and either way you deserve what you had coming because you ultimately took the risk(s). Cheating makes you an undeserving person, taking the grade rank someone else should have got. The person supposed to be in the top 10? Yeah he is 11 now thanks to you, and thats a difference maker. This is an example.
Im with ppwiz on this, your morals are fucked if underage gambling that has no effect on you leaves a bad taste in your mouth and you cheat regardless that it doesnt feel right to you. Not sure why you would ask this except you are looking for a reason to make yourself feel better when you cheat.
In fact this somehow feels like underage gambling, where a hs student takes the risk to cheat and getaway, possibly being held back a grade or punished. But ultimately in the end, if you succeed, it is not over. It would cause a chain effect, you take up one of the few positions in a company, where someone else would have gotten it if your grades werent as good. Sort of like cutting in line.
