The guilt is eating me alive because I'm thinking of copying someone else's answer on a quiz today.
That's not good. Do you trust the person to have the right answers?
You can't really trust anyone in this world.
You shouldn't copy off of someone else's work. You won't learn how to do it correctly and they might have the wrong answers.
Maybe. We will see how it goes and maybe I will get a good grade.
But it won't be your good grade, it will belong to the other person who you copied from. You also won't know the topic or subject well because you copied it from another person's work. You are just hurting yourself.
