What makes a hero?
Interesting question. One I asked My Father several times as I was growing up. He always answered the same way...
"A hero is someone who did something that was necessary, that nobody else wanted to do, even if he did not have to do it."
Personally, the media has cheapened the use of the word "Hero" by over-using it and applying it to media darlings.
To quote Chris Rock: "Hillary Clinton's a hero? She's not a hero! AQUAMAN'S a hero!"
But, anyway, I've seen acts that were heroic, and many of them were never recognised by anyone who had been there.
In game turns, a Paladin is one of the most heroic classes out there. He beleives in something greater than himself, and is willing to die for that belief, for that cause, and those ideals.
One thing, regarding heroism, is to remember point of view. To Americans, Benidict Arnold was a traitor for giving up the fort to the British. To the British, he was a hero who knew his duty, while the rest of the American heroes were nothing but traitors. So someone who is a bad guy to the PC's, might be a hero to everyone else...
