There's not enough information given just from the title to really know who Henry Magee Worstman is. He might be the protagonist, and his name might give some hints about his personality. For example, 'Worstman' could suggest that he has some negative traits that are central to the story. Or perhaps it's a satirical name, and the story is about subverting our expectations of someone with such a name. But again, this is pure conjecture without delving into the novel itself.
I'm not sure as there isn't a widely known novel with such a character name. It could be a very niche or self - published work. Maybe it's a character created by an emerging author and not much information is available without further research into that specific literary piece.
Since I haven't read a novel specifically named 'Henry Magee Worstman in the World', it's difficult to say exactly who he is. He could be an anti - hero, a complex character with many flaws. In many novels, characters like this are used to explore different aspects of human nature, like greed, envy or self - destruction. But without reading the actual book, this is all speculation.
