Luna Lovegood. Even though others treat her poorly because she doesn't fit the "norm" she holds no anger towards them and is still a great person. She also seems to have an understanding of death, but doesn't fear it. She sees the beauty in things that others fear.
may sound weird... next to ginny mcGonagall... don't know I just kind of think she's a really strong woman and would have done a way better job than dumbledore who was just ready to decide over the live of a child and play chess with them...
Not a fan of HP
