After a long brawl, Frederick finally won! He showed Covey that he should respect slaves more and that he shouldn't just whip them to whip them. After that day, Covey never disrespected or laid a hand on Frederick Douglass ever again.
After Frederick defeated Covey, he saw what vowing to not act like a slave and standing up for yourself can get you, and he continued to use that motto for the rest of his life. He knew that one day when he was free, he would show the world that slavery is horrible and freedom is way better and should be offered to every human, white or black.
