harry as a horcrux i firm stand behind the idea that he isnt one. why would voldemort try to kill him in the first book then, why would quarrel try to kill him why would voldemort in the book two send the basalisk against him. if harry was a hocrux voldemort would try not to kill him its just that simple. we know that voldemort did infact use the killing curse on harry in the first book cause it is told directly to us that the spell rebounded on him. rowling herself said that. so harry as a horcrux, No.

here is a thought for another horcrux idea though hogwarts itself. what if the school was a horcrux, its got all of the possiblities to be one, Voldemort loves it, it got strong links to power, history and all the great wizards. also NO one in the right mind would destroy the castle thereby destroying him. hogwarts for all intense purposes has been immortal and will probably remain so because of all the magic oen the castle, how would voldemort have put the magic in there, maybe in the visit for become a teacher at the school, He and cumbledore both knew he wasnt going to get the job, maybe thats why he went for an excuse to be at the school so he could turn it into a horcrux.

on dumbledore, he is dead and i think his murder was planned by himself, also have a feelin that snape is good, or will turn good in the end. wormtongue also has a life debt with harry, wonder how thats going to play out.
