Do you agree that plagiarism is wrong?

Absolutely wrong...even if you're not caught. Plagiarism is a form of stealing. You are stealing possible royalties and income from the author of whatever it was you stole.

And hearken, a copyright is assumed on all images and text even if a copyright symbol is not indicated. But it is not plagiarism if you cite your source when you copy something into your own work.

At my university, if a student is caught stealing text or images from someone else and uses it in their own work, that student is expelled.
