Based on this document, do you think John Brown was a "misguided fanatic"? Why or why not?

There's no document provided, I'll answer to the best of my knowledge

The abolitionist John Brown attempted to garner attention and do his part to abolish slavery by murdering three individuals who supported slavery, and later tried to host an armed uprising where he would lead slaves to raid a federal army in Harper's Ferry. The attack was unsuccessful, and he was later executed. His actions were radical, and in my opinion very misguided and would only lead to more violence.

That is my take on it, though I recommend you get your own opinion because that is a very opinionated topic.
