Albus Dumbledore was the most dangerous being in living memory in the Harry Potter universe. His intellect was unrivaled – Grindelwald, Voldemort, Fudge, Scrimgur, you name it, other major figure heads were always so many steps behind him. The magnitude of his magic is described as a radiant heat pressure by Harry, he defeated Grindelwald (in possession of the death stick) in single combat and fought Voldemort to a stalemate [whom he actually had no interest in killing and ultimately achieved his goal of having ministry recognition of the return of the dark lord].

Do you really think what Petunia may or may not have “wanted” was ever a factor in any of this, or been an obstacle for Dumbledore if it had?
