Which Harry Potter character would you be and why?

Hay this is for all you potter heads out there which Harry Potter character would you be and why? 

I would be Dumbeldor as I have made many mistakes in the past and I still regret them find it hard to forgive myself for all the bad I have done wrong. I may not be as wise as Dumbeldor but we both have our regrets his because of the death of his sister and the choices he had to make with Harry Potter and Voldermort and me just with the mistakes I have made in the past.
