A Typical Point

J.K. Rowling's Harry Potter series seems like it's without a fault, but sometimes some things come up which can be seen as totally to be things to take the plot further. For instance, two horcruxes were kept so safely which were the ring and the locket, but the others were just about thrown around. The cup in Gringotts was definitely an easy one, as also were the diadem. I mean, come on, can it be that there would be no curse on that diadem, a piece of Voldermort's soul. How can that be possible? Also in the locket's safety, Dumbledore elaborates that Voldermort might have wanted to keep a way back inside the cave. But why would he? Even if he does go there and even wades into the lake, full of the dead, even then they can't kill him, because he has his horcruxes. And he could use fire. These things could have been better in the books, especially as Rowling expanded the book so much as to continue it over seven books. After that there is no scope for lightness in the book from such a powerful character.
