I took a chunk out of the women's neck
What exactly did you take from that woman?
I took her life away
Murdering someone is completely wrong and an inexcusable crime. It's never okay to end someone's life when there is a nonviolent alternative possible. You should turn yourself in to the police for what you have done since taking the life of another person is illegal and requires punishment.
Maybe if I turn myself in to the police, she won't miss me that much.
I feel like you are in a place where you need help. Turn yourself in so that you can avoid doing damage to others.
