User blog:Sally5217/harry potter series is confusing

Dear Harry Potter Wikier,

Hi, i'm back. I was reading Harry Potter and the Deathly Hallows and a question come up to me.the question is :Who took the most effort for killing Voldomort?i mean if it wont for Dumbledore ,then Harry wouldn't know what to do.But if it wont for Harry then Voldomort would be still alive,in the book of course.But if it wont for Voldomort then Harry wouldn't be Voldomort worst enimy, and wouldn't kill Voldomort.so yeah it's confusing.
