Eh...then I find this whole thing to be poor writing. It's established that Voldemort, like most would-be Dictators, is paranoid to a degree. I mean, he gets one prophecy from an idiot and look what he does. To say that he doesn't even have some sort of magical security that alerts him, "HEY YOU LOST A LIFE. FIVE MANS LEFT." is very out of character.Originally Posted by Chris 2.0
Voldemort does not seem like a person that is just relaxed and content with the world. He is very afraid of losing his power, even more so since he has lost it before.
About living Horocruxes, my guess is that people have their own souls, which no doubt has some risk. Harry very well might have been a failed attempt at a living Horocrux.
