Two part reading response: Beloved by Toni Morrison

Plot:
Beloved is a true story based on an Afro-Amarican woman. She was a slave at the 'Sweet Home'. After the death of the owner the house was taken by a man known as the 'school teacher', who treated slaves very badly, tortured them. After these treatmenttreatmentss, Sethe decided to run away and thought that it would be better if she killed her children than letting them be tortured and raped. She killed one of her daughters. Sethe locked herself and felt the blame inside her,but the return of Peter D made her feel better and she stated to feel like she had got over it.
My opinion: 
So, I think that Sethe acted like that because she thought it was the best way possible to escape slavery. She, as a mother couldn't bare the pain to see her children treated like animals, raped and so on
Maybe the slavery itself had made an impact on her and she was kind of afraid to see and handle more pains. 
Also the desire to see some quiet and free days with her family pushed her to run away, but she knew that they(the strong white people) would find and punish them until they die. So she decided to take their lives by her own. 
Her relationship with her daughter doesn't look like  those mother-daughter relationships. She develops a dangerous maternal  passion that results in the murder of one daughter, her own "best self".
