"They hate because they fear, and they fear because they feel that the deepest feelings of there lives ae being assaulted and outraged."(p.390, Max)
Even when pleading guilty Bigger had no chance of making it. The hate that the white people had for bigger was so strong that it didn't even matter why he did what he did. In the eyes of the white people Bigger was just another black criminal that needed to be dealt with. And to have one of their white girls killed by a black man there was no way that he would stay alive. So in reality hate decided the outcome for Bigger's life before he even went to trial, the day Bigger killed Mary he too died with her.
Hate and fear run hand in hand, most hate comes from fear. Bigger hated so many things but it wasn't the fact that he just didn't like them. Bigger hated out of fear, and he used hate as a way to vent the fear he had for something. Bigger feared the white people because they had power over him, richer than him, and for those reasons Bigger hated white people with a passion. Vice versa the white people were scared of black people, why because they didn't want them to have any power in society they didn't want them to have equal opportunities it scared them stiff, so out of fear they discriminated and the hated.
