What do you think Sir John Rowell means when he says, "man is the worst"? Explain your reasoning

This question is about "The Hand".

He meant that the human being is more dangerous than wild animals like hippopotamus, tiger and gorilla.

Explanation:

"The Hand" is the horror story about the mysterious death of Sir John Rowell and the disembodied hand that appears several times in the story. However, before being murdered, Sir John Rowell talks to the narrator about his adventures and his passion for hunting. He claims that he has hunted several wild and dangerous animals such as the hippopotamus, the gorilla and the tiger, but that he was not afraid, as there are more dangerous animals, which he also likes to hunt, such as man. That's because man is rational and knows how to fight back. Wild animals, on the other hand, lack these skills.
