I'm planning to let my classmates fail an assignment because of me.
Why do you want to let your classmates fail?
I don't like them and want to take revenge on them.
It's wrong to make your classmates fail due to your inept actions. It's horribly childish of you.
No fuck you. I don't care about turning in my homework. They're going to fail for being stupid anyway.
If you care about your future, then doing homework is essential to success. Your classmates are going to be upset with you and remember this transgression. If you don't care about homework then ask the teacher to be excluded from the work assignment at least.
