My reaction to the killing of Mary Dalton

I can understand why Bigger killed Mary. He did not have the intention to kill her but the intention to not take responsibility for killing her. When Mrs. Dalton walked into Mary's room, Bigger was panicking--his blood boiled, he did not want to be accused of raping a white woman. Then there is the planning part, he planned on how to hide the facts that he killed Mary by saying that a Communist did it. Jan is a Communist but he's still white; Bigger should reconsider blaming Jan.  Overall, I see a pattern in Bigger's actions from when he smothered Mary to when he came home to sleep it off. Bigger was thinking about how they will electrified him to death with an electric chair if he doesn't do everything he did to protect himself. The whole time, it was fear that made him do the killing, the planning, the burning and the beheading.
