To some point, I feel for him on that front. However he's the perfect example of what the greybeards said, the biggest downfall of the Dragonborn is their arrogance when they let their power outstrip their wisdom. Miraak was the first, both of the Dragon Blood and as an example of what the arrogance of such power can wrought. Even Tiber Septim himself was a victim to this when he dropped his guard and got his throat slit.
Arrogance seems like a common trait in the Dragonborn. This might explain why the Greybeards are extremely careful on what they teach the Dragonborn as far as new shouts goes. Miraak confirms this when he tells you: "I know things the Greybeards will never teach you."

"Dov wahlaan fah rel.
We were made to dominate. The will to power is in our blood. You feel it in yourself, do you not?" This quote was directly taken by Paarthurnax himself.
Why do you think Hermaeus Mora stalks down new Dragonborns with promise of knowledge? Because the Dragonborns are easy prey for him. He's an equivalent of a child predator luring children into his van with promise of candy and ice cream. Almost all of my Dragonborns falls prey to this Prince. because they crave knowledge to further advancements their Dragonborn powers that the Greybeards otherwise wouldn't teach them.
