So after reading http://www.fimfiction.net/blog/297594/on-heroes-violence, I wanted to ask around on here as well to hear other thoughts on this. (You don't have to read the blog; just linked as a reference to what I've read. I do agree with a lot in it).
What is the nature of a hero?
Can a hero use violence to save the day (including killing the 'villain')?
Could there be a difference between a hero and a good person?
I would like to hear some thoughts on this and possibly have a respectful discussion on the subject.
