Final answer:
Lafayette's statement about Charlie's 'badness inside him' implies a hereditary aspect to Charlie's negative traits, as supported by the theme of hereditary evil and influence from one's lineage as described in the text excerpts.
Step-by-step explanation:
When Lafayette says about Charlie, 'Say he got his badness inside him', it suggests that Charlie has an inherent tendency towards negative behavior or qualities. This points to the theme of hereditary evil, implying that Charlie's undesirable traits may have been passed down through his lineage. The texts provided describe characters who struggle with internal vices and sins that are portrayed as being part of their bloodline or heredity. These characters battle the influence of their ancestors' actions and societal conditions on their own lives, despite not desiring or choosing such a burden. The mention of 'actual slime and want of their hourly life' and 'the evil of an entire race flowed in his veins' provides evidence that their actions and condition may not be entirely within their control but rather a product of their inherited circumstances.
