“I want you to listen to me very carefully, Harry. You are not a bad person. You’re a very good person, who bad things have happened to. Besides, the world isn’t split into good people and Death Eaters. We have all got both light and dark inside us. What matters is the power we choose to act on. That’s who we really are.
My take on this Quote from the world of Harry Potter, said by the character of Sirius Black means that nothing is black or white but they are shades of grey. This means to me that, there’s so much grey to every story: nothing is black and white and due to this, you don’t know why someone acts the way they do because there are so many reasons they act like this and we don’t know what these reasons are or what they are for.
