More to the point, what good does making them nearly impossible to acquire serve?
Better to hid, so no one can destry them, and V can manipulate the Death Eaters enough to get any of them to collect it. The farther apart they are, the better his chances of never dying, and isnt that the point of doing that?
From my post 176
I would think that DD's hand turned black when he put on the ring (horcrux) because the ring started to control him and Snape had to kill the hand and destroy the ring to get it to stop. I would not want to be the one to drink from Hufflepuff's cup or put on the locket.
