Pain to Remember-III

In the past Elise, who had grown up feeling herself close to Church could never believe angels could kill humans. Angels are holy beings and they were born to protect humans, yet now she learned that Angels could also harm people, "Have you ever seen and Angel who killed someone before?"

Ian brought a blanket on his side to drape it over her leg, while answering to her question, "I have seen it. You have heard from the chick about Death Angels, remember?" she nodded her head. 

"I remember Hallow told me that they don't have mind like other Angels. Is that why they could kill humans?" because they don't feel emotion, they wouldn't feel guilty to kill people, is that what it was?
