How do the master's treatment of the slaves, as depicted in chapter 1, affect Douglass?

In chapter 1, Frederick Douglass elaborates on the actions of his cruel master, Captain Anthony, and vividly describes the horrific beatings his master would often give his Aunt Hester. Douglass recalls waking up at dawn numerous mornings to sound of his aunt's heart-rending shrieks. Douglass goes on to mention that Captain Anthony would often tie her up to a joist and whip her until he was exhausted. Douglass recalls the gory, horrific spectacle and mentions that the harder his aunt screamed, the harder Captain Anthony would beat her. Douglass writes that he experienced an "awful force" the first time he witnessed Captain Anthony's cruelty and cannot commit to paper his feelings during the terrible spectacle. Douglass then describes the particularly terrifying episode when he witnessed Captain Anthony tie up Aunt Hester for disobeying his order and mercilessly whip her until she was covered in blood. The episode was so traumatic that Douglass hid in a closet and feared that he would also be whipped. Overall, Douglass is both traumatized and terrified of his master after witnessing him brutally whip Aunt Hester on several occasions. The memories of witnessing the brutality continue to haunt Douglass as an adult, and he struggles to elaborate on his feelings of terror and shock.
