Righteousness (as far and wide as the clouds in the sky)

Righteousness, originally uploaded by crassus08.

I went to check on the translation dictionary and righteousness was the best word to explain “义“. Though i think that a better explanation would be that 关羽（云长）was the best example of being loyal to his sworn brother even if it means sacrificing his life.

Isn't it also living a purposeful life? Life is short, like 关羽 had, he died in his prime but his name was preserved forever in the latter generations. Its been almost 2000 years since and everywhere he is still revered and idolised. Who better an example than him?
