.There are good angels and there are bad. A fallen angel is an angel that is considered one who has lost God's grace. These girls were never to bad, just good enough to make it into heaven and be released of the torchure they indured. That was until they began to hate the person who killed them and in turn, were put right back into a place of suffering. Until they can learn to be free of all this pain and forgive, it all will never end.
