This is an interesting part of American History, the one who is now synonymous with the word "Traitor" and has entered our daily lexicon. Benedict Arnold.
Going to school right down the road from where he lived as a child and where his mother is buried (visited the grave once, it is quite a cool graveyard) I've always pondered whether or not the backlash towards him is justified.
I believe it is not justified. After all, we were not yet a full country, just colonies in a state of rebellion with a loose sense of unity. What was there other than a rebellion to be a traitor to? He was mad that credit was being taken from him, even though they were his actions and that he was being passed over for promotions, who instead went to people who had taken credit for his actions.
So I believe that the backlash that Benedict Arnold has gotten over the years is not justified, we can not change what his name and reaction to him has become, but we can change our perspective towards it.
