But the biggest change in him was that he didn't care about blood purity anymore. Muggleborn, halfblood, pureblood, it all felt the same to him. Why? Because he saw all the muggleborns that he used to consider beneath him, fight. He saw them fight while he ran like a coward. He saw them fight for their world. For a better life. He saw her fight. Fight more then she ever had. He saw her contain her screams as his crazy aunt tormented her while he was in the same room and didn't do anything to stop it. Her screams still keep ringing in his head every single night when he tried to sleep.
