How can something be “wrong” if you aren’t harming anyone?

Cheating on tests isn’t “wrong.” Essentially you are just fabricating a lie and lying to a teacher/school that only cares about you as a commodity to be shipped off as a worker to be exploited by capitalists isn’t amoral.

If you harm another working class person you should feel guilty. But morality doesn’t apply to the class war. You cannot do anything “wrong” to the ruling class or their institutions. They have been doing wrong to you your whole life anything you do against them is justified self defense and nothing you or I can do would ever reach a fair punishment for their crimes.
