In "The Adventures of Sherlock Holmes," Arthur Conan Doyle explores the theme of consequences associated with violence and deceit. The quote suggests that those who engage in violent acts or scheming ultimately face the repercussions of their actions. It emphasizes a moral lesson: the harm one intends for others can backfire, affecting the perpetrator instead.

This notion serves as a cautionary reminder that integrity and justice prevail over wrongdoing. Characters in the stories demonstrate that scheming against others can lead to one's downfall, illustrating the idea that negative intentions often return to haunt the instigator, reinforcing the concept of accountability in human actions.
