 Clay's father (who was not deeply religious) never forgave Clay for his part in his mother's death and emotionally shunned his son, ultimately telling him that he's "not even worth it" upon an initial refrain from slapping him.This deeply affected Clay, causing him to seek out his father's abuse as a means to gain any sort of emotional response and validation.The two formed a casual hatred towards each other and blaming each other for the death of Clay's mother.
