Final answer:
Without explicit context of Huck's actions, a specific answer on what he does to feel better after a 'horrible thing' cannot be provided. Generally, characters may reflect, create excuses, or take solace in nature to alleviate feelings of guilt and seek redemption.
Step-by-step explanation:
The question seems to center on a character's remorse and subsequent actions to assuage guilt. The referenced texts suggest these characters are experiencing self-reproach and looking for ways to reconcile their actions either through justification, rationalization, or by taking solace in nature or improved conditions.
However, there's no direct mention of Huck and his specific actions to make himself feel better after a horrible deed. To provide a response, the context of the action Huck took and the exact content of the book needs to be referenced. Without that, any direct response to what Huck does specifically would be speculative.
However, the excerpts provided from other works can be used to explore common themes in literature where characters seek redemption or console themselves after committing deeds they perceive as negative. For example, self-reproach is a common reaction, where a character may internally debate their actions or create excuses to diminish the feeling of guilt.
Nature is often used in literature as a setting for reflection and solace, offering a respite from the societal pressures that may have influenced the character's regretted actions. Characters like Huck and others might find solace in the beauty of the natural world, as it provides them with a peaceful environment for contemplation and resolution.
