Is John Brown a Martyr or Murderer?

I believe John Brown is a Martyr because he was an abolitionist,  sided with the North, and killed because of his beliefs. He believed slavery was wrong and that union should be free of slaves. On the night of October 16th, 1859, John Brown and his sons led an uprising. His goal was to collect all of the rifles from the arsenal and kill anyone standing in his way. He believed he was god’s chosen one and for that reason he must kill for his cause. The next morning, the US Marines arrived. John was captured and sentenced to death. He died December 2nd, 1859. On his execution date, the North flew flags at half mast and church bells tolled. John Brown was remembered as a martyr in the North and a murderer in the South.
