Hermione didn't regret killing Draco. Not for a single second. But, she couldn't deny that there was still a hint of sadness buried deep within her when she allowed her mind to wander to thoughts of him. He lived a wasted life. Perhaps, to a certain extent, they all did. There had been many opportunities for the wizard to turn away from his anger and his need for revenge. The only person he had to blame for his fate was himself. Still, there were quiet moments when she would remember a look or a touch that seemed genuine. Almost like the person he truly was deep inside all of that hatred and fury was trying to break out of his internal prison. It was heartbreaking. Maybe they could've been something real in another life.
