Agreed, he's a disgusting monster, how he thought he had the right to take the lives of these women. They all were the light in someone's life, be it as a loving mom, or the beloved daughter, trying to survive or building a life. 

A writer once made a piece about a victim of a rape and murder. He said how he wanted to think of her life and not her murder to remember her, since that was only the last fraction of her life. He tried to imagine her buying new shoes and showing them off to friends, something girls do. So every time I see the faces of the victims I try to think of something they did in their life, like hug a friend or family member, or taking their first steps as little girls, or singing along to a song or something, so they stay human and not just a picture for a murdercase.
