Do you know what the definition of a hero is? Someone who gets other people killed.
Not by my definition.
The first and craziest lemming is no hero. A double agent sure as hell isn't. In fact any scumbag who betrays trust is not.
I don't like Terry Pratchett's definition either, that a hero is someone who fears his friends more than his enemies.
We have to call people, who brave their fears to stand up for principles, something.
While we are at it, defending means standing up to those that agress against you or people one cares about. That's with violence or without.
I'll buy this liberty thing, but I'm going to do it and keep my own definitions of hero and defending.
