IS JOHN BROWN A MARTYR OR A MURDERER???

I think that John Brown is a murderer because he killed five men because they had different opinions than him. John Brown was so worried and upset about there being slaves that he took it to far and decided the only way to fix this problem is by killing people. Frederick Douglass had once warned John Brown that attacking a federal building was a mistake and would get him killed, but John Brown would do anything to try and stop slavery.  John Brown had once said “I John Brown am now quite certain that the crimes of this guilty land will never be purged away but with blood.” The statement John Brown is saying means this problem will never be solved unless there is war.
