Is Charles Van Doren really at fault?

In the movie, Charlie says out loud "It just doesn't seem right," so he knows going along with the scheme is wrong. Not illegal, but wrong for so many reasons: He was faculty at an Ivy League school and his lies made the real scholarship he'd done look worthless and he brought shame to his family. Charlie also says something about trying to imagine what Kant would make of this, so there's no doubt he knows he's doing wrong. You own your words, so tell the truth and you can't go wrong. Charlie went way wrong and brought it all on himself, hurting academia as well as his family's reputation.

In my opinion I think he's at fault.Charles Van Doren is a GROWN MAN and knows right from wrong.It's simple to me.He knew what he was doing was wrong and he did it anyway.Just like the people behind the show knew they were wrong and continued doing it anyway.
