"Story of the Door" Reaction

Through out the chapter, "Story of the Door", there were many memorable moments. One that stood out to me is when the man, Mr. Hyde, trampled calmly over the child's body and left her screaming on the ground. As Enfield is telling the story, he said "it wasnt like a man; it was like some damned Juggernaut". This moment makes me think that he man who walked over the girls body might have a mental condition because what he did is not normal. The article I read was about mental illness and what the man did reminds me of that article. A theme that might be potentially implied through this moment in the text is that not all people do what is expected.
