This reminds me of the Cherokee quote about two wolves inside each of us. One is filled with evil based on sins, the other is all that is good based on noble traits. The one that gains control is the one we feed. The beasts are inside every one of us. Feed the one that you wish to be and starve the other. Association with others, without identifying which beast they are feeding can lead you along the same path. This particular young woman has willingly been led down the wrong path and gorged the evil within her, she is now dominated. It is by no means a completed battle, she can always starve this wolf and feed the other, but only if she realizes what she has done and determines to change. It is difficult, but not impossible.
