"He knew himself a villain—but he deem'd
The rest no better than the thing he seem'd;
And scorn'd the best as hypocrites who hid
Those deeds the bolder spirit plainly did.
He knew himself detested, but he knew
The hearts that loath'd him, crouch'd and dreaded too.
Lone, wild, and strange, he stood alike exempt
From all affection and from all contempt"
-from The Corsair, by Lord Byron, Canto I, Section XII)
One of the most critical lessons to learn for literature students is that it's all been done before (yes, even that last phrase, in a Barenaked Ladies song, but I digress). Almost without exception, any character in any work fits an established type. This applies to real life as well as fiction, and Johnny Manziel is an easy one: he's a Byronic hero. If I'm already losing you and your thoughts drift more toward science than Romantic poets, check out Jacqueline's explanation of Manziel using Coulomb's Law here. Check it out either way, it's great, and I'll still be here when you return.
