In the quote from "The Count of Monte Cristo," the author Alexandre Dumas highlights the presence of danger in the world, symbolized by tigers and crocodiles. These creatures are powerful and fearsome, but Dumas warns that the greatest threats often come from people rather than nature. The metaphorical use of two-legged tigers and crocodiles suggests that individuals can embody these dangerous traits, making them more perilous than animals.

By emphasizing this idea, Dumas encourages readers to recognize the potential for malice and treachery in humanity. He prompts a reflection on the nature of danger, suggesting that those who walk among us can possess a savagery that surpasses that of wild animals. The message serves as a warning to remain vigilant against deceit and betrayal from others in society.
