Final answer:
Victor intended to promote human happiness but ended committing a deed of mischief and malice, underscoring literature's theme of actions with noble intentions leading to negative consequences.
Step-by-step explanation:
Victor is wracked with guilt; though he intended to further the cause of human happiness, he has ended in committing "a deed of mischief and malice." This indicates that the consequences of Victor's actions contradict his original noble intentions. The theme of unintended consequences and the pursuit of human happiness are common in literature, reflecting the complexity of human actions and the moral considerations that come with them. Whether it is a character attempting to overcome the limitations of his abilities, or walking a path fraught with moral ambiguity, literature often explores the concept that actions in pursuit of good can sometimes lead to evil, as seen in the examples provided.
